OK I have went back thru all the shotgun slug post I could read and need some clarification on some things.
First I read only shoot sabots thru a rifled barrel. I have also read you can shoot regular slugs thru a rifled barrel.
Now the reason I ask is I have an 870 with a rifled barrel and have been trying multiple types of sabot slugs at the range. I have been getting a wide varity of results but have narrowed it down to two different slugs that seem to work in in this gun... The winchester super X 2 3/4 in with 1 oz sabot ( I accidently picked up a box of 3" mag also but I can't see much difference between them and 2 3/4 shells) These slugs are rated according to the box at 1400 fps .
The other slugs ar remington premier accu-tip 2 3/4" 385 gr sabots rated at 1800 fps.These are a little less consistant butgood enough for me. Now I bought this gun used at a pawn shop and I looked it over real good and the barrel didnt show any defects.
Now I have a co-worker how just purchased a brand new 870 combo and asked me to take him to the range and help him sight in. He shoots iron sights only and cant seem to see thru a scope for some reason but to each his own. Now when he shows up he has 8 boxes of shells and every box is non sabot remington or federal ( they were only $3 a box he says!) So we shoot every box thru that gun and these cheap rifled slugs actually group ALOT better than my $ 11-16 slugs! I was led to believe you cant shoot non-sabot slugs thru a rifled barrel because the slugs are rifled already?????? Whats the truth ?????
