First post.
Always a first
Are starting up a custom build of a bolt action 6,5 Grendel with a friend.
Have ended up with what barrel to use, and the twist rate.
Bullets that I intend to use is 120-130gr.
Mostly the Lapua Scenar L in 120gr, Scenar 123gr.
The Hornady ELD 123gr and ELD 130gr.
Might be lighter Lapua bullets also, but this is not something that will be in the desicion.
Barrel length will be about 18-20", and a supressor will most likely.
Have made some diffrent calculations on the Berger Bullets Twist rate stability calculator with this bullets.
It seems that 1:7,5 gives good figures, better than the same in 1:8 twist.
But when I search the internet, the 1:8 and also 1:9 is more common.
Any thoughts on this forum?
