FULL VIEWS OF THE COMPLETE GUN
PURPOSE OF THE RIFLE: Well by now, if I have to explain that then, you aren't paying too much attention....lol! Just joking. The gun is built to not only hunt small to medium game such as Jack Rabbits, Coyotes and Prairie Dogs, it's also built to mostly shoot extremely long air gun ranges at various targets. It might even take the occasional HOG (plans this summer...possibly). This gun will be able to shoot pretty far.
BALLISTICS: Using the Lyman 258-130 (BC of .305) bullets in particular, this gun and scope combo should be capable of making 500 yard shots. At 870 FPS and a ZERO of 75 yards, the bullet drops some 560" or 46.6 FEET or 15 yards or 107 MOA in which I have a total of 120 MOA. So 500 yards+ is DEFINITELY doable in this gun. Plus, that's using the crosshairs as the aiming point. If I use just about all the MOA or clicks in the scope PLUS the MRAD hash marks, im good for another 100 yards EASY. Increasing the FPS will only make the gun shoot flatter and provide me with even MORE range. Hell, you just might see a video of this gun vs my TIKKA T3 in 6.5x55 Swede which is a long range machine in its own right. More info to come on the SWFA scope and its full potential as well as the ballistics program and projectiles of choice. The Ballistics program I use for my cast bullets is by GSEVEN. It's accurate!
ACCURACY: While my standards so far are lenient, I currently expect about 1" @ 100 yards as a minimum standard. But that is NOT all I want. For now, and until I learn the gun/caliber more, my standards will become more strict as too what I expect from it. So far and with only a handful of bullets down the bore, my groups are decent and acceptable to my standards so far. I don't have a multitude of groups thus far with this gun but the groups I do have give me some insight into what the future (mods) of this gun will hold. What I love about this gun so far is that the bullets hit just were I aim time after time and that in itself is so reassuring. Here is what I have so far but these groups were repeated 3 times during the range session. HOLE FOR HOLE, SHOT FOR SHOT.
Here is a video of the INTRO to the Corsair as well as its 1st range session:
INITIAL THOUGHTS: To say that I'm impressed with how this gun turned out is an understatement. I'm ecstatic and I still have more changes to make to her. And I can't wait for that day when all the upgrades are done. I love this gun so far. From muzzle brake all the way back to the butt pad. Its beautiful, light, it's not really loud due to the long barrel, it handles and points very well and shooting it offhand is so far a dream. It's OAL is pretty long but it doesn't really feel like it. I'm getting used to that long barrel and muzzle brake.
Stay TUNED!
Looks great, thanks for sharing!
ReplyDeleteIts my pleasure Jim. And thank you for tuning in sir
DeleteI'm presently gearing up to convert my yet to be purchased AirForce Condor to 7mm. By, "Gearing Up" I mean, waiting for my tax return to arrive.
ReplyDeleteI've always suspected that the 7mm caliber would make an excellent candidate as a long range air rifle projectile. Your post just confirmed my suspicions.
I've been a long time bullet caster so casting my own projectiles or even making my own bullet molds isn't a problem.
I don't want to come across as a self-appointed know-it-all because I certainly don't know it all when it comes to long range air rifles. My comment is in regard to your projectiles of choice.
A while back I discovered that I could shoot 223 caliber store bought jacketed varmint bullets out of my modified 22 caliber break barrel air rifle by swaging them down to bore diameter. I had to build a special swaging die that would allow me to extract my swaged bullet once I had squished it down to size; and it took a while to figure out the optimum length of the swage that would leave just the right length of driving band at the tail end of my bullets.
I ruined alot of perfectly good bullets before settling on a driving band of a little less than 1/16".
I mention this because I fully intend to try this same process with 7mm jacketed varmint bullets once I get my converted 7mm Condor up and running. I found that the store bought varmint bullets are just a little more consistent in terms of shape and weight so by swaging them down to the dimension of my bore, it creates a self-centering bullet with very low friction as it moves down the bore; while at the same time having an adequate gas seal at the tail end that equates to decent terminal down range ballistics; for a break barrel 22.
The great thing about this process is that you can do it with store-bought hollow pointed, spitzer boat tailed bullets for an even better ballistic coefficient than you could hope to get with cast bullets.
I've never mentioned any of this on any of the forums I belong to because even though I absolutely love this type of long range air gunning innovation, I hate having to deal with the nay-sayer, self-appointed experts and internet trolls that seem to find great pleasure in crapping on other peoples dreams and ambitions.
Best of luck to you on your future long range air gunning endeavors.
If you get a hankering to try swaging some of the higher BC 7mm jacketed store bought bullets, remember you heard it here first.

Tim,
ReplyDeleteThat's pretty dog on interesting man. I hope you post up videos and pics cause that would be just about the most interesting thing I've seen.
I wish you tons of success and thanks for tuning in.
Hi T I have built some usft long rangers extreme bigbores .30 -35 cal and just built a 7mm with a 30" tj barrel and I have the latest mold for the 95 grn bullet . This was supposed to be a working barrel on a working qb78 . When we checked checked the bore and was actual never cut and machined on the tight end so we cut it and crowned and cut the leed . Then tried to push a sized 284 round it was impossible with out a hammer .
ReplyDeleteAfter a day of r&d we made sizers from 283 to 280 . And got a useable fit , the gun now shoots 740 fps with 1800 psi regulated . Haven't shot paper yet but it seem promising . So I have a question or two the gun you show in the video your gun teathered is very quite for 3000 psi to push 30-35 pellets at 1750 -1800 the guns we build are very loud this 7mm is very sharp and loud . Next you say that you had a tighter barrel to bullet fit then we ended up with with284 -2788 lands and grooves . What kind of lube are you using ?. Thanks Linzie
