[QUOTE="Ross1147, post: 1663106, member: 106919"] Just took it to the range today to fireform a few more cases and see how some Varmint Grenades shoot. The fire form loads are 105 grn Berger’s with 31.5 grns of IMR 4895 jammed .02 into the lands. I started the other day with 32 grns but think that was a little hot. I also split 2 shoulders out of 25 when forming. Today with 31.5 grns I had zero split in 30 cases. Average speed was 2852. ES was a little high at 29, but I wasn’t picky when throwing charges because they were just to form brass so It was 31.5 + or - .2 grns The Grenades were shot with already formed Dasher brass. Seated them all with zero jump and started at 34 grns IMR 4895 and stepped up .5 grns every 4 rounds. At 35.5 I was seeing slight ejector marks and at 36 it pierced a primer so I stopped. Best ES and vertical group was at 35 grns at 3443 FPS with an ES of 5. What I found interesting was how much .5 grns increased FPS in this thing? My bigger Rifles usually gets ~30-40 FPS give or take for .5 increase. This thing was getting 70 FPS per .5 grn increase. First picture is of a 15 round group with the fire forming Berger’s. Second picture is of the VGs. I threw one out to the right but still minute of squirrel, and a VG at 3400+ should leave some pink mist!
