    Hi All

    Anyone shooting the above combo at all, what powder charges have you used, what have the results been like?

    308?

    im guessing the 140 might be a little on the fast side id say 150 possibly would be better

    I worked up a decent load with 178Amax and N140 with Lapua brass and CCI BR2 in my 20" Tikka Supervarmint. I settled on 42.8 N140 for an average of 2548fps. Shot pretty well - half MOA. I did carry on higher but groups started to open up.

    My load data of course, provided for reference only. As Spud says though with the heavier bullet N150 would probably give you a wee bit more speed. (If you need it.)

    I use 44.8grs of n150 behind the 168gr amaxs,2750fps and accuracy you dream of .n540 will be good too, I used it behind the 175gr smks

    Would have thought this would be a little too fast for this weight and you'll be running relatively low case fill, N550 maybe, not the 540 though...and we're all working on the assumption this is in a .308.
