My Rem 700P (1-12twist) struggles holding 1 inch 5 shot groups with 165 Sierras. 168 Bregers and Sierras are worse. ( Both with 4064) I've jammed and jumped with little luck. 150 Sierras shoot 3/4 inch groups (all at 100 yards) but are horizontally strung but tight. Today I shot 125 Sierras with 43 gr of 3031 and even though they have a huge jump to reach the lands they shot 3/4 also, but with the horizontal string. I loaded these mainly because I had them never thinking they would shoot as well as they did.
I have to be doing something wrong but I can not figure it out. This is all off a bench with rests....neck sized RP brass...CCI primers....weighed powder.
Why the stringing and why horrible results with 165/168 bullets?
