I have a question about barrel twist in 6mm br. I 'm wanting to buy a 6mmbr cal. rifle. I own 2 TC encore rifles in 25-06 and muzzle loader. The logical thing to me is to purchase a barrel from TC's custom shop in 6mmBr cal. They only come in 1:10 barrel twist. Iwill be shooting bullet weights only in the 80 - 90 gr range ( i have a 223 for lighter bullets). I don't plan to use it for nothing but target and varmit shooting and to introduce a small child to deer hunting -(90 gr.) Would the 1:10 rifling work for this configuration or should i look into other manufac.s of encore barrels? TC's custom shop is much cheaper than some of the others with the same features. Thanks
