30 BR 125 TNT and 135 bergers 1:10

[Ogre6br]

Hi
Has anyone tried the 125 TNT and/or 135 Berger out of a 30 BR??

I have a 1:10 twist,26 inch- unchambered) barrel I would like to make into a 30 BR and am wondering what velocities people are getting.

thanks

later

A 10 twist is WAY too much for those light bullets. If that's all you have, maybe you could sell it or trade it for a more appropriate twist barrel. You could probably get 2850 to 2900 with the 135's. Others get 3000 with 118's, so it's a relative thing.

With 135 FB Bergers, I am getting 2880 fps, but that's in a 14 twist bbl and they shoot xlnt. You will have to run 150 gr. bullets and heavier in the 10 twist bbl.
Good luck,
Gary.
