"UNSCIENTIFIC" TESTING v1: The .257 cal MHP

MHP stands for Modified Hollow Point.

Some years back, a guy south of me and myself started making x's in the HP mouth and cavity of the 25 cal Crow Magnums and we started calling them MCM's (Modified Crow Magnums).  We would then go out for Jack Rabbit hunts in San Diego and would have a blast testing these pellets.  The MCM's were pretty devastating on the HUGE Diego Jacks.  And we would always post about the MCM's and the results we were getting.

Today, I don't even shoot the CM's as I've found better HP's in the Predators and HP's that i cast myself for my mid and big bore airguns.  For my 308 and 45 HP's, i had not really experimented with a Modified version of one of my cast HP's simply cause the mouths on the bullets are so big that it's really not needed.  WELL, I should have experimented with the anyways as airguns cause of their lower FPS, usually need all the help they can get.  And if you shoot HP's, why not help the bullet start to expand.

Well, now that I've converted my Talond/Condor over to 257 caliber, I've found a jewel of a bullet in the LYMAN 257420 mold.  I recently had one side of it converted to HP and the other side was left as an original Flat Point.

After casting and sizing up a bunch of bullets with the newly modified mold, i decided to try and make a batch of the HP's into MHP's by using the old Razor Blade technique of cutting a x or + into the nose of the HP and then test its effectiveness against a regular HP and the FN bullets. 
So now it would be 3 versions of only 1 bullet.


In this video clip, I'm testing the 3 bullets versions into various mediums.  In the video, you will also note the vapor coming from the muzzle blast as it was cold and just about raining out.  The vapor is pretty cool to see on video and shows just HOW MUCH AIR WE ARE PUSHING in airguns.  I call the video "UNSCIENTIFIC" simply cause i used and ancient technique to judge how effective the bullet versions are on target.  I simply use the old, EYES, BRAIN, EARS and video technique to judge effectiveness of the bullets.......lol!  Nothing scientific about it....lol!

Rubber Mulch bullet trap (for airguns)

Was at work and the boss asked me to trash some left over stuff from our equipment.  He said that whatever i wanted from the pile, i could take.  Well, 1 gallon of cutting oil was first on the list (especially for free).  The other thing i quickly spotted was a brand new 12x12x6" junction box (electricians).  I quickly though, "hmmmmm, bullet trap using rubber mulch that i've been hearing so much about as of lately"...lol!  So HOME the junction box came.

Well, today i had time to get over to Home Depot and i quickly found the mulch of course in the garden section.  I had my choice of Red or Brown mulch.  Oh My, that 1 too many choices more than what i was expecting.  I was expecting only BLACK since i know its made from shredded tires.  Too my surprise, there was no black but only red or brown.  No probs either way.  Brown it was.  I also picked up some Jig Saw blades to cut a section out of the junction box.

Needless to say, there really isn't more to really talk about when it comes to the actual project itself.  The idea is pretty straight forward. So here it is in a nutshell. 

The pics are self narrated:












The nice thing that i noticed right off the bat is that its much cleaner than using wood backers or plumbers putty.  Wood splinters quickly and gets messy pretty quick when using it in your home.  You also blow through it pretty quickly and it gives feedback when hit.  So wood is not quite when shot.  Plumbers putty is awesome but you can soon blow right through it after shooting in the same area.  Plus you get a lot of it laying around the garage after you've shot a few hundred rounds through it.  Its pretty hard to also clean out plumbers putty and reuse it.  Plumbers putty is quiet though when shot.

I'm really liking the rubber mulch target trap.

"RISE" of the TalonDor 257

I know.....the title is all dramatic huh?  LOL!  As the title states, I have brought my old talon/condor back to life and even gave it a well deserved caliber swap.

Back Story (short version):  I purchased a Air Force Talon in 22 back in 2005.  As most Talons go, it came with a 18" .22 cal LW barrel.  While being a fun gun, I found it difficult to reach "WAY OUT THERE".  Because I hunt in the desert, I needed a gun with more oomph!  So I bought a 24" LW 22 cal barrel along with a Condor tank.  Along with the longer barrel and Condor tank, I performed some tuning that I learned over on the TAG.  The gun was pushing 22 cal Eun Jins at over 1075 FPS in 22.  To make a long story even shorter, I then purchased a 25 cal barrel and breech and top hat combo for even more power.  The gun was a thumper to say the least.  But after all these mods and a LOT of hunting, I was never truly satisfied with the all out accuracy of the gun.  Even after the gun was de-tuned.  After some years of ownership of the TalonDor 25 and the introduction of the Rapid25, I retired the TalonDor in about 2008 or so.  Here is a old pic of the TalonDor in one of its many earlier guises:

Present day:  After much pondering and taking a look at "WHATS" out there, my taste have turned to long range shooting with airguns.  I mean, I've always done long range shooting with airguns since i started in them but, I've always wanted something that was not only powerful but, something that was accurate and had looks.  I also wanted something that shoots BULLETS and not pellets.  I mean, if your gonna go long range, why not use the right tools.  And while pellets can travel far, they simply do NOT outperform bullets.  The Daystate Wolverine had come to mind but, it's a odd caliber with odd weighted bullets for the power plant.  So i got to seriously thinking about what caliber I would want.  I already had a 454 and a 457 and a 308.  It wasn't until RJ Porter post that it hit me.........hmmmmmmm..........257!  Why not?  I had already done the big and medium calibers so why not a small caliber.  And the idea was born.  But what gun could i do this in.  My Dragon Slayer was already in 454 and it's very successful in that caliber.  The Corsair can't be taken apart (yet) so it was out.  Both of these guns though make 250 FPE and are perfect candidates as a base.  But I did not want to change or mess with those platforms as they both perform.  And it wasn't until one day, i was in the garage cleaning up that the idea hit me.............THE TALONDOR!  WHY NOT!?

DYOTAT100:  In comes Doug Noble or DYOTAT100 as he is known on the TAG forum.  I had been following his work and post and had found out he lives right down the freeway from me.  I PM'd him about being interested in performing my "ideas" on my TalonDor.  He was more than game and more than up to the task.  GAME ON!!!!!!!!!!!

My Ideas:
The concept for this gun was simple.  I wanted a long range rig.  Something that could shoot accurately to OVER 75 yards!  The same gun could easily reach out to 200 yards also.  And do it accurately.  And using the Air Force platform would be a stretch (no pun intended).  The caliber would be 257 with a barrel that had a fast twist to keep the bullet stabilized while reaching out.  I also wanted a 1 piece bushing for rigidity while in the frame.  Doug also came up with the idea of a custom "tight" fitting frame end cap.  For even more rigidity, I contacted Adam Vigil here on the TAG about his WOKGUARD15.  I also ordered a DPMS AR15 pistol grip with beaver tail tang that I had to trim down to help support the bottle of the TalonDor.  I got rid of the old custom pistol grip.  I also decided to relocate the forearm closer to the Wokguard15 so everything in the vicinity would be fully supported and create LESS frame flex.  I also had Doug install a second bolt into the forearm for more rigidity.  The gun also already has a Tri-Rail.  A new hammer weight, hammer spring would also be added to the gun.  The hammer weight is of the Bore Riding design and made of brass.

Here are some pics of all the custom parts and the gun completely assembled:

BULLETS OF CHOICE:  LYMAN 65 GR FLAT POINT BULLET MOLD IN 257



OVERVIEW AND PERFORMANCE OF GUN ON ITS MAIDEN OUTING:
Needless to say, I am extremely happy with Doug's work.  His work is as nice in person as it is on the forums.  I learned a lot about the Air Force line of products through Doug.  Having a machinist or gunsmith run through these guns is pretty much NECESSARY.  But on to the positives.  I made a video of the gun while out on its maiden shooting session so I won't go into too much verbal detail.  But I will say that the gun is a performer and it lives up to my expectations.  My initial groups printed in the 5/8" CTC range at 60 yards.  I was also able to print a 1.050" CTC group at 110 lasered yards while shooting a small resettable popper target which is in the video.  The gun also performs best at power setting 5-8 and 3100 psi and makes 132 FPE at that setting.  The gun also has a bit of a kick and is pretty loud.  But that's ok, I don't mind loud especially when the gun performs.



HOLD SENSITIVE:
Yes, the gun is very hold sensitive.  Like most Air Force guns, she required a light hold.  A snug hold makes the gun groups horribly.  The gun also prefers PURE LEAD bullets over hard cast or bullets that are cast just a lil bit harder than pure lead (???????)

THE GUN FULLY ASSEMBLED


FUTURE MODS
All silver will become black (lol).  The Morgan Adjustable butt pad will soon be replaced with a WOKBUTT

Casting bullets for Air Guns

Being and avid shooter/gun nut has provided me with some of life's simplest pleasures.  One of those pleasures is casting bullets for my Air Guns.  Like reloading, bullet casting is very rewarding.  It's cheaper than buying bullets, it's fun, and it's educational.  And when you shoot tight groups with your bullets, the smiles don't stop.

In the video below, I cast bullets from a recently purchased LEE 113 grain/.309" mold ($19.99).  I had been wanting a lighter bullet for my Corsair 308.  Something lighter than 150-170 grains so what better than the 113 grains.  By nature, when using pure lead, the bullets normally come out about 7-10 grains heavier than what the mold is advertised to produce.  Putting the bullet closer to 120 grains.  My ideal weight is 115-120 grains.  After casting and sizing, the finished bullets came in at about 119.5 grains which is well within what I wanted.

The other attractive quality about the bullet chosen was it's flat point nose profile.  The meplat on the nose and the weight of the bullet would provide plenty of smack for any small game or coyote i would shoot with it.  LEE Molds posted on their website that the BC is .199.  This is great for an airgun as most Diablo shaped (traditional design) pellets are around the .010-.0370 range.  So .199 BC is a drastic improvement by airgun standards.  Coupled with good speed, a BC of .199 would provide great long range velocity retention.

I've already managed to shoot some 75 yard groups as well as hit water filled bottles at 175 yards with much success.  My Corsair currently pushes the 119.5 gr bullets at 885 FPS.

Let's take a look at some pics of the finished bullets and LEE mold:





SO LET THE CASTING BEGIN:

REDO: Dragon Slayer 454

Been out in the garage working on the Corsair 308 and the Dragon Slayer 454.  Stopping a leak in the DS has been fun to say the least.  Hard to get parts.  A new LEROY RODUNER fill nipple here and a NEW O-RING there and some new parts here and she seems to be good so far.

 A while back, I had a buddy machine me another hammer weight set up so the gun would now become a separate cock and load gun.  I wanted the custom hammer to be heavier than the factory hammer.  The O.E.M. hammer weighs 1.9 oz and the custom one weighs 4 oz. including cocking handle.  I also opened up the air-tube hole a tad bit more to MAX....lol.  My buddy also made me a custom DELRIN Transfer Port and we got rid of the brass TP.  I also moved the Bi-pod more forward and filled the previous stud hole with WOOD BONDO and retouched it up.  I also scrounged up a stiffer smaller spring than the one my buddy sent me.  And began trimming it too length.  Yes, the mainspring is a DUAL setup.  I also polished the heck outta the hammer and that gave me a little more FPS also.

Already got some round ball for it and i also have some Mark Whyte 175 gr Truncated Cone bullets.  Jerry Boyenga at SUREFIRE Slugs is ALSO sending me some 220 gr Raptors.  So far, from a 3000 psi fill, 454 cal Hornady Round Balls are doing 898.6-909.6-875.6, Jerry's 220 gr Raptor slugs are doing right at 700 FPS for the 1st shot but will be just a tad faster on the second shot.  More chrony work to come (gun is kinda loud in a TOWN HOME community..lol).  The 175 gr Mark Whyte bullets.......NOT SURE YET!  Haven't chronied them yet.  But they are probably gonna do about 800 FPS or so.

Some Pics.

3 GUN Ground Squirrel Hunt

Finally got a break in the weather and wanted to take advantage of it.  I've been testing a new gun and this would be a perfect chance to carry it afield on a shoot.  More on that gun though at a later date.  The guns were:  Dave G.-RAVEN .177, a Logun Solo .20 and a Rapid .25.  I would spend the first half of my hunting day sighting-in.  The Raven produced 2 different .660" and .700" CTC groups using the JSB Heavies.  The Solo .20 produced two .5" plus CTC groups.  The Rapid came in making a .393" CTC 5-shot group.

Raven .177 cal:

Solo .20 cal:

Rapid .25 cal:

Sighting in my Rapid .25 cal:

After the sight-in, it was time to hunt.  My longest shot of the day came from the Rapid 25 and it was a 93 yard head shot.  Nothing more satisfying than making a connecting shot at that distance with an airgun.  I managed to make shots from about 40 yards out to 93 yrds and got roughly a dozen squirrels.

The 93 yard Rapid head shot:

Raven .177-40 yards head shot:

Raven .177-49 yard head shot:

Logun Solo .20-38 yard head shot:

Logun Solo .20-40 and 51 yard head shot:

Rapid .25-40 yard head shot:

Rapid .25-57 yard neck/spine shot:

Rapid .25-61 yard shoulder shot:

Rapid .25-65 and 75 yard head shot:

THE HUNTING ACTION:
