So, the first two outings with my first 6BR and load development using Varget and 105gn AMax, Lapua Scenar 105gn and Sierra Matchking 107s reveal best groups asa follows:-
AMax: 27gn & 28gn Varget loads give groups which at worst are cloverleafed at 2749fps and 2788fps respectively. Either load is first class and I may try 0.2 gn increments between 27 and 28gns.
The next AMax "good load" is 31 gn which isn't quite so good.
Lapua Scenar 105: by far the best varget loading was 29gn giving 2909fps one ragged hole group.Nothing between 27gn and 31 gn came close.
Sierra MK 107: 28gn of Varget is the mutts nuts, almost one hole,me to blame) @ 2787fps, 29gn @ 2878fps and the slight prospect of re-shooting 31gn which nearly gave a group acceptable in this company @ 3051 fps.
So, I've got excellent loads for 100 yd shooting but they're all on the slow side. Trouble is, ballistically they're a bit flimsy on paper for 600 yd shooting soshould I stick with them or should I keep 100yd and 600yd loads separate?
