[QUOTE="DMCI, post: 32377, member: 1730"] This is what I am getting out of a 28" 1 in 9 Lilja 3 groove 7mm WSM: Win LRM Primer Berger 180 VLD Win Cases VV N165 Powder Grs. Velocity(SD) 61.0 2737 61.5 2757(6) 62.0 2780 Group size: .313"@100 yards 5 shots. 62.5 2800 63.5 2858(10) 64.0 2890(15) 75.3*F 29.75 in Hg 49.7 RH Looks like more investigation for accuracy only needs to be made for loads from 61.5 to 63.0 Initial indications are that rounds have very excellent consistency. On a second occasion, we visited the range with 180 Berger VLD and VV N165 but with F215M, a magnum match primer: 62.0 2834(9) 62.5 2866(8) 63.0 2895(7) 63.5 2916(6) Group size: .401 @ 100 yards 5 shots. 85.0*F 30.2 in Hg 25% Humidity Interesting in this case the best group was the heaviest load. Some minor primer extrusion around firing pin, nice bark, light to medium recoil even with Break and 15# gun. With WLRM primer, best group was 62.0 to 62.5. This is an excellent mid-range target load. I think for now the F215M load will be the one loaded for target shooting.
