Full power loads would be possible to near 100 yards with the left barrel reasonably on target. The right barrel would be at least 18" off target, high and left. 50 yards means an 8" composite group with this double rifle and full power loads. I know the shot placement well enough that I could compensate for crappy regulation with factory loads, but this is not optimal. I am worrying myself to death over whether I practice compensating for full power shortcomings or whether I worry about sufficient penetration of hand loads that will strike the bull every time. Given the left barrel would be ok wit h full power loads, I would need to adjust many years of front tigger then left trigger discipline to be opposite so I use the left bbl 1st?
