I'm really wanting to do a short barreled 7saum. I'm not just sure what twist rate to go with, my plan is to shoot 162 - 175gr bullets. I've read a bunch of different threads on here, as well as, rokslide, accurate shooter, snipers hide and others. What I'm finding is that none of these really talk about short barrels. When I do a twist rate calculator, a 1-9 or 1-9.5 twist is the answer. I'm thinking a 1-8 will fit the bill.
Here's my thought process:
Thank you for your input!
Here's my thought process:
- 18" barrel, minus 2.5 for the shank, leaves 15.5'' to get the bullet spinning
- 1-9 twist: 1 and a little over 2/3rds of rotation in the barrel
- 1-8 twist: almost 2 full twists before leaving the barrel
- Tikka T3X action
- Mesa Altitude stock
- CarbonSix 18" Sendaro barrel
- New Bottom metal
