So, I'm playing with my PC Cast .311 160gr Lee Molds
I had success making this a plinking round for shooting steel on my 300 BLK.
Powder coated and gas checked, these come our pretty big, like .313-.316 depending on the amount of "shake" before "bake".
Although I have LOTS of bullets left, I thought I'd play and work up some loads for the Mosin. My goal would be 4MOA at 100 yards so I could use them to shoot 12" steel gong at 100 yards offhand.
I have a Mosin PU Sniper with a pristine bore. And I have a long established Load for it with Sierra Soft Point hunting bullets and Varget.
I know it would shoot different with my M44 offhand but I figure for now, I'll do some playing around with load development to see how the scoped Mosin would fare with these. If I can get them grouping as well as say Tulamo, I'd be set.
Doing a bunch of reading, I built up 5 each of
7gr W231
10gr Unique
27.0-29.0 IMR4895 (1 each .5gr apart)
W231 was about 2" groups @ 50 yards subsonic at 1050fps avg
Unique was also about 2" groups @ 50 Yards at 1350fps avg
Across the 5 loads of IM4895, the groups were about 2.5" with the last 2 3/4" apart. The 29gr was 1610fps and the velocity started to stabilize there so I think I'll load some more up around the 29gr range to try to see how they group.
For Grins, I shot 3 of my Sierra bullet reloads and the 3 bullets were touching.
