I chose these two loads out of the 5 that I had pressure tested a few months ago.
First load was 40 grs of Steel under a BW 18(BP 18) wad and then the slug. All this was crammed in a 3” Fiocchi hull and fold crimp. Now for those of you that know me, knows I’m very particular and detailed about my finished crimps, since crimps play a large part in slug accuracy and is often overlooked. The crimps on these were rather domed and that bothered me. I figured the accuracy wouldn’t be great and I was right.
With 40 grs of Steel, pressure was really low, but the recoil was STOUT. Believe me. Shots were all over the place. I think if I tamed it down to maybe 35 grs, those groups will tighten up because I’ll have more room to crimp. My crimps where very inconsistent with this load. Maybe I’ll replace the flex seal with a x12x seal and pressure test those. It should be within SAAMI specs.
38 grs of Blue Dot produces better accuracy. Still need to play around with this a bit. Don’t really care for groups this loose at 50 yards, but it’s a start.
