What IC choke for H13 #7

[Remturkey]

I currently have my 870 supermag set up with a IC .665 and h13 #6 3.5" shells. I want to try the h13 #7 and was wondering if I need a different diameter choke to get the best results. Thanks

I would shoot it and see my 1187 shoots 6 and 7 great with .665

I'm gonna try some of the #7s also out of my 1187 with IC .665 choke.  It should shoot great.  Guys are getting unreal patterns with the #7s.

.665 with my 870 and 7s I got 323 at 40

i think that .665 would be fine but you might be able to choke it down to .660 see an improvement, IMO 7's can be tighten down a bit more than 6's can

im very happy with that load and an ic. 665.

Thanks guys. Was gonna try the magnum blend but with the mixed reviews ill stick with the straight 7's.

That's a good decision
