Extra full vs super full

[Longshanks]

Bought a Carlsons 24" chrome lined barrel for REM 870 and have both SF .665 and XF .687. Have a bunch of Hevi 13 3/2/6's and 3/2/7's. Thinking TSS through the XF .687 and Hevi 13 through the SF .665.

I've got a buddy that shoots 3 1/2 inch Hevi 6's out of a .665 IC with good results.  I would say give those Hevi 6's and especially those 7's a chance.  3 1/2 Hevi 7's is all I shoot in my 835 and they are devasting.

Thanks, I'm hoping the Hevi 6's and 7's will work. Have a bunch of that and TSS seems to be going up by the minute. Saw it was $79.99 + tax at Bass Pro the other day for Fed 3" 9's. Have 6 left.  Gonna have to shoot what I have and make it work.

Have 4 box's of the Win LB 3" 6's. Not sure if I trust them anymore.

I have a Beretta AL390 with IC .665 and shoot Hevi 13 3", 2oz of #6.. great pattern and a 40 yard gun all day long.
