Then pinning the barrel will have a much smaller effect on overall accuracy.
You would probably be better served saving the money and trying out a bunch of different slugs to determine which one your particular gun likes.
It really is amazing how poorly some gun/slug combinations shoot, but the same gun and a different slug can be a real tack driver.

i agree.... i shoot a 870 wingmaster with a cantilever hastings (1:32 twist) and an aimpoint red dot up top. i can cover a 3 shot group with a 50 cent piece at 50 yards when shooting lightfields 3"hybred elites (orange box). groups still hold tight out to 125 yards or so.......on the other side shooting hornady sst's i couldnt hit the broad side of a bard @ 50yds!!!!
