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.
