I have not been able to get 5 shot groups consistently under 2 inches at 100 yards in any LR or AR caliber I have, including the Spectre. Semi pistols, no problem, ARs or LRs, big problem. Also, I have shot cast in every type of action you can imagine with outstanding results but for the life of me I cannot get cast to shoot as well as I want them to in any AR or LR platform. And I've done all the tricks normally associated with shooting cast bullets. I have shot cast bullets in stainless barrels for 5 decades and I have never had a problem or seen that there is any difference in SS or CroMo when it comes to shooting cast. Accuracy reductions expected of course with the 0.002" oversize bore and chamber neck. So an intentional 9.3x39 build you could shoot handloads with 9.3mm commercially available bullets and also fire 9x39 cheapo Wolf imports through as well. Heck, some of the 9x39 builds might already use 0.366" barrel blanks spec.-ed for 9.3mm rather then the correct 0.364" Russian spec. Such a dedicated magazine would also be the cats meow for wildcat 8.88x39 ("triple eight by thirty nine") as well since it is a 9x39 simple neck down same body same headspace to use US standard 35-cal bullets and barrel blanks which offers a wide range of loading possiblities from very fast supers using light weight projectiles to subs that are just as heavy as the 9x39 offerings plus plenty of cast lead bullet mold options.Įdited to add: Although to my knowledge no one has intentionally built one yet, a 9.3x39 wildcat is also an extremely logical choice to make use of readily available bullets and barrel blanks. I am hoping that C-products will eventually come out with a dedicated purpose built 9x39 magazine for AR-15s in that chambering. I have not seen it but quite a few people have asked for it. And you are right, there is not much data but a guy there does have a spread sheet that he will send you if you email him. If you can get a seat stem made or modified to fit your bullet better than my seat stems do (CH-4D dies) then you might not have to go through the BS of seating the bullets with the case held upside down.Īll my data is on the 458 SOCOM Forums under the Spectre. bullets since my Spectre is a kicks and giggles 8.5 inch SBR anyway. It works great like that but is a royal PITA to do, so I backed down to 250 gr. I shot some 300s but the only way I could get bullets to seat without deforming badly at the tip was to barely seat the bullet, then put the seat die in a hand press and seat the bullets while the cases are being held upside down so the powder was not being crushed between the base of the bullet and the bottom of the case. Neither expands but shoot great and are very accurate. In my Spectre I have settled on two bullets, the 250 gr. The Barnes 160 TTSX shoots well but needs 1800 fps to expand, and if it won't expand past about 75 yards in the GRRR it won't expand much past the muzzle in the Spectre. I have not used it in the Spectre per se but I see no reason it would not work just fine. 338 Spectre, and the only bullet I can get to expand at any distance, i.e. 338 barrels on hand but that was a year or more ago. Check with him because at one time he did have some. He made the barrels for Marty originally and still can make them but you need to supply the blank, barrel extension, and bolt most likely. Paladin Machine Shop Service can make you a barrel. ![]()
