What cartridge are you shooting?So I have cut it down from an occasional 3" 3 shot group to 2" 4 shot is the worst.
I had only tried 117 Hornady SSTs with IMR 4350 in it. So I also tried some Sierra 100 and 117 SBT with the 4350. They all shot a 2" 4 shot group. I then switched to Retumbo(which I have less than a pound of) and printed 3 shots tight and the flier made it a 4 shot 1" group.
Today I hope to check 4 Sierra 117's and another 4 Hornady 117 SSTs with Retumbo.
Yesterday the 1" 4 shot group was definitely the best this rifle has done.
Here is a 3" group before bedding.
A 2" after bedding.
And the best 4 switching to Retumbo.
