Gunsmithing 1-11" twist on a .300 Win Mag??

[buckey]

Anyone ever run a 1-11" twist on a .300 Win Mag??


I plan on using a 1-11" on a .300 Win Mag hunting rifle build -only going to use 180 and 200 grain ammo, nothing heavier. I know that the 1-10" is the standard but I'm gonna give the 1-11" a try.

I'm pretty sure all AI's are 11. I know my brothers is anyway and it shoots the 208Amax's really well

Should not be a problem with anything up to the 208. Lots of folks shooting the 208 out of the 308 with 11 twist and doing just fine. The added velocity of the win-mag will easily handle the weight of bullet you are looking at.

It will run 220's fine as well.
