First build need help with barrel

Postby Mdhart79 » Tue Aug 30, 2016 1:36 pm

Hello, I am new to this forum and the 450. Have plans on building a hunting gun for lower Michigan. I have a savage model 10 in 308 as a donor and ready to order my barrel. Planning on ordering from mcgowen just need help with length and twist. I plan on shooting factory ammo no hand loads. It seems like a lot of talk of 16" or 20" and 1:16 or 1:24. My question is has any one gone with a 18" and if so what loss is there to the 20" and I see mcgowen offers a 1:18 twist. With some saying 1:16 is to fast would 1:18 be better or should I stick with 1:24. Thanks.

What bullet weight are you planning to use? Factory ammo shoots best with a 1 in 24 twist. Check out he reading on Tromix and Bartz barrels. :D :D :D :D :P

look up Precision Rifle here in Michigan, they post here too. they had some McGowen barrels on GB awhile back, but were longer, (24-26") but they might have something shorter on hand in stock.

My bolt gun is a 16t, 200gr Barnes the lightest I've shot in it, handled them fine.

That barrel should do well.

Please keep the forum informed about your progress, both positive and negative and about lessons learned from oopsies.
