THE GUN (TD257): For those not familiar already with this air gun, the TD 257 started life as a Airforce Talon .22 caliber airgun. I then bought a 24" .22 cal barrel then switched it shortly thereafter to a .25 cal pellet shooter. Now this is back when the .25 wasn't even popular or in the hands of the general public. After converting to a 24" barrel 25 caliber air gun, I soon bought a Condor valve from Air Force and thoroughly enjoyed the boost in power. Many years later, the gun sat on the garage shelves for many reasons. The main reason being the accuracy was not consistent enough for me. In comes Doug Noble over on the TAG forum and he custom machined my guns internal parts along with the installation of a TJ Enterprises 26-5/8" barrel in .257 caliber. Put all of the above info together and VOILA, I now have what I call the TD .257 (TalonDor .257). Talon frame with a custom "Condor" valve by Mr. Noble with a .257 barrel.
Now, on to the highest praises. With this kill, my absolute love for my air gun confirms why I think the 257 is such a accurate, devastating and fun round while using air power. This rifle has hit a coke can at 446 yards (over a quarter mile) and was what I believe the FIRST to do this. It has scrambled raw eggs sitting on golf tees at 175 yards. It has decimated small colonies of ground squirrels and jack rabbits. It has VIDEO posted half MOA groups at 160 yards. And with this kill, it has now taken 3 coyotes. The 257 continues to impress me after all these years and there is no other small bore air powered round quite like it!
THE AMMO, THE MAN: Now, for those of you that follow me and my AIRVENTURES, you know that with this gun I shoot a variety of self cast slugs. One being the very popular Lyman 257420 which is custom hollow pointed. Every now and again, I get to test new slugs. As of lately, I've had the pleasure of shooting some new to me, SWAGED slugs by Nick at Nielson Specialty Ammo or http://nielsenspecialtyammo.com/. Nick contacted me via one of my favorite air gun forums and offered to send me quantities of .357 and .257 custom swaged slugs. Being a sucker for new ammo, I could not and would not say no. Nick owns a trapping company out of CA and has always been a shooter of various powder burners and used to reload most ammunition he shot. He got into PCP's when he needed a solution for putting down animals he trapped. As he got further into Air guns, Nick noted a serious lack in accuracy with over the counter lead ammo for big bore airguns. He started out casting and then learned about the swagging process which he liked a lot. Diving right in, he purchased a Corbin hand press to learn the process. Shortly after he bought a hydraulic press and many dies, punches and related equipment. Nick spent over a year developing his craft and doing research and testing on various slug designs. I have recently been giving Nick feedback and evaluating his slugs. Which leads me to this kill. Nick recently sent me some 77.3 gr Rebated Boat Tail HP's that I found to have some serious potential and asked him to remake them at 79 gr instead. Being a swagged projectile, the maker quickly has the ability to make the projectiles heavier or lighter by simply adjusting a die. Longer per caliber makes it heavy and the reverse for a shorter bullet. Nick has some pretty exciting ideas for projectiles that show great promise and will be available for retail. I won't let all the cats out of the bag and save future info on his slugs for future post. Lets take a pictorial look at some of the slugs and targets from previous test sessions. These pics show how much time and detail goes into the testing sessions to find out what works. These are not all but just a few:
Later, I set up my new Caldwell chrony and began to test the same exact bullet for muzzle speed. I was amazed that the slug was traveling 910 fps with the chrony set up 6 feet from the muzzle for 145 FPE! BC is still untested as of yet because the slugs are in their infant state but, being a RBT projectile with a pretty slick ogive, they retained enough downrange fps/fpe to totally penetrate a large male coyotes chest 120 yards away and cause massive trauma! More info on these slugs to come!
Stay Tuned!
