Re: bad round grouping
Is it fouling bad in 4-5 rounds? Does it "feel" rough pushing a patch through? I've seen an ammo change cut groups in half, but 4-5 inches should be beatable with almost anything. You keep coming back to the scope, if it was working on something else its possible its got some stress in alignment from mounting. Any pattern to the grouping? Does adjusting the scope move the group, does it hold zero group to group? Depending on make it could be just shipping to have it checked out. Cheaper than ammo these days.
