6BR Load development

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?

You gotta love the 6MMBR because it's sooo accurate with several different powders. I'm getting 2910 fps with the 105gr A-Max's/N-550/CCI-450's and Lapua Brass. BTW, It's shooting in the low .2's for 5 shots @ 100 yds. I've been handloading for 25+ yrs and have never seen such a cartridge...
