Of the bullets I have loaded the
least, the 250 FTX is it. There's more than enough data around here for them already. I have about 125 of them squirreled away though. Now for the 240gr XTP Mag, I burned through a box of 100 in 5-shot, 100yd recipes. To be honest, I've never felt that I "cracked the code" on a consistently good recipe from my 20" 1:24 AR. Once in a while, Id get three touching, only to settle for an overall 2" group. Even the occasional barely 1 MOA but then everyone gets an occasional truffle. I know how to milk every tenth of an MOA out of loads but the 240 has eluded consistent 1 MOA 5-shot groups at 100 yds, off of a BR setup with a 24x scope and concrete "Rock of Gibraltar" shooting benches. That having been said. If you happen upon a recipe that produces as good groups from the 240 XTP Mag as the 250 FTX, don't ever change it and please share it.
FWIW, I have had about the same luck with the 300gr XTP Mag. I'm into pressure signs just about the time they start tightening up. Not so with the 325gr (resized .458 FTX). A royal PITA to resize but they shot pretty well with AA1680. Got them on sale, so figured what the heck. Borrowed the step sizing dies. If I were into Bison hunting, they'd get the call. Off subject once again.
