I was really close to selling this gun but for now I’m keeping it. I did some more testing with it today and shot some pretty good groups.
All bullets are seated out touching the rifling (hard). (This made a HUGE difference in group size with my painted bullets)
Two 5 shot groups for each load, all CCI LP Primer, BE-86 powder
All groups are at 50 yards.
My bullet, RCBS 44-250K 421 are painted. Flat base
8.0 gr - 2.03” , 1.35” Average 1.69”
8.5 gr - 1.2”, 1.2 Average 1.2”
9.0 gr - .69“, 1.9” Average 1.28” This was a confusing two groups. The 2nd group, 1st shot was left, 2nd, 3rd and 4th were clustered in one big hole, 5th shot was right. I think it may be me inconsistently holding the gun. Being a break open action, everything is moving when I‘m unloading and loading. It’s a lot different than shooting a bolt or my heavy barreled AR-15…
A buddy gave me 3 different bullets to try, all unpainted, all gas checked. All loads are with 8.0 gr of BE-86
300gr - .875”, 1.52” Average 1.19”
250gr - .7”, 1.1” Average .9”
228gr = .81”, .77” Average .79”
I need to borrow his molds and get some gas checks. I’m really curious now to see if it’s the gas checks making his bullets more accurate, the lube or both. I’m thinking it’s the gas check.
I wasn’t noticing any leading with the unpainted bullets but I was only shooting one group and then shooting a group with painted bullets. I didn’t want any leading to be a factor in the test.
