GM drop in barrel

[twotoescharlie]

got a 58 cal. for my renegade the first of this week. shoots great. using a .575 ball that I already had a mold for. the balls are a drop fit without a patch. used 70-90 grains of 2f and 3f black, patches were .010-.019 lubed with moose snot. getting 1-1 1/2 inch groups at 50 yards which is good enough for almost 70 year old eyes with open sights.
Problem- shooting 4-5 inches to the right. F/S moved 1/32 to right, rear sight adjusted to left almost as far as it will go. (have less than 1/32 left to adjust.) any and all suggestions appreciated.

it appears that this barrel will shoot almost anything that is loaded in it, just cannot get the group centered. believe it has the 1 in 70 twist.

Assuming you're not doing anything wrong, it just sounds like it's not straight...I'd send it back immediately and have them straighten or replace it...had to do that once with a TC RB barrel...it happens occasionally.
