I have a savage 110 tactical in a B/C stock. It shot 44.0 Varget and 165sst consistently in a ragged hole. Then recently the groups blew out over 1in. Always 2 in a hole with one high and left. I did have a lot of copper buildup I cleaned and groups went back down. Then after 20shots out again. I cleaned again with sweets and fist group was .3in. Yesterday I shot fist group was a cloverleaf at .9in. I then had 4loads to try with SW Precision powder. All 4 were .75-.9. But all were 2 touching and one high to the left. Each group Look almost identical. I do know on at least one the groups it was the second shot that was off. Is this type of group telling me something I’m missing?
