I was out the range yesterday doing some load work with some 165 using 44.0 grs of RL-15. Decided to try different primers so 1st 5 used CCI 200, 2nd 5 CCI 250, 3rd group of 5 FED 215 and 4th groupd of 5 REM 9 1/2 M.
1st ones shot were the ones primed with CCI 200, group was not the great, next up CCI 250 tightend up the group with oen flyer being me. then the FED 215 group was about the same as the CCI 250 then the REM 9/12 M, I had one flyer but the group did a vertical string on me. the avg velocity was 2,575 F.P.S which seems a bit slow to me. So does anyhow have a good load that they have chronographed that shoots real well. Thanks... The rifle is a rem 700 22 inch barrel.
