I have calculated the twist with 105grs. A-max to be 8", and with 70grs. TNT to be 12".

If I choose 8" will the TNT be to stable and loose some in the precision categori? I will use this mostly with 90-95grs. for deer hunting.

I have a 6 Rem 40X with a Hart 1 in 8 which shoots the 70 Nosler BT's amazingly well to a long way out there. I do not subscribe to the over stablized club... nor the little bit pregnant club either. Go with the 1 in 8 and see greater expansion due to the rotational effect on the deer bullets! Enjoy

I agree 100 % with 308Sako on this. One in 8 will allow you to stabilize any available 6 mm bullet available that I am aware of, even the 115 gr VLD Bergers, if they are available in Norway.

For target shooting I am a big fan of the Sierra 107 grain match kings. although I understand there is a 108 grain or so Target bullet from Finland. ( Lapua) would be interesting to try that, the Finns do good things with Rifles and bullets.
