Best Accuracy with Mossberg 500 12ga


I began slug hunting 3 years ago in Ohio. Long time rifle hunter in WV and got hooked on bigger Ohio deer. My question is: I purchased a Mossberg 500 12ga with a ported rifled barrel that chambers 2 3/4 and 3 in shells. I just put a scope on my gun and have shot 6 boxes of Horandy sabots 2 3/4 which I can only get groups at 50 yards in the 6 inch diameter range. I just picked up 4 boxes of your Lightfield 12ga 2 3/4 Hybred EXPs from Cabela’s. Will be heading to the range this weekend to sight in 2 1/2 high at 50 yds. I also ordered 3 boxes of the 12 ga 3 Hybred Elite. Do you know if one shoots any better through the Mossberg 500 cambered for the 2 3/4 and 3 in shells? Also can I expect the 3 in shells to shot the same as the 2 3/4 in shells? Thanks for the great website and information. I have learned more from your website about slugs than anywhere else.

That size groups are common with most brands of sabot that use a pistol or ML bullets in a 20 & 12 gauge bores.

Shoot in your Hybred Exp 2 3/4″ high at 50 yards (dead center above the aim point – no left or right – dead center above) and it will be zeroed at 100 yards. With that same sight setting the Hybred Elite 3″ mag. will be zeroed at 125 yards and -4 inches at 150 yards. This is Lightfields SameSite accuracy system. See the web site for more info.

Those figures represent true trajectory curves. How hard you hold onto your gun with your left hand can easily change them. The amount of upward movement that you allow the gun to move while under recoil will alter your zero in a heart beat. CONSISTENCY in your hold, shot to shot, is the name of accuracy game when it comes to slug guns.
