Any reports on Hevi Magnum Blend out of the 20??

[Longshanks]

What's the best choke for the heavyweight number 7?

Thanks for the updates on the mag blend shells. Found a good price on them and was wondering if they were worth a shot.  Looks like the numbers arent too different than the numbers i am turning with Hevi 6's. Think i will save my money.

Federal HW 7's

Beretta 390/ Good success with the Hevi 13 .573 choke and the Federal HW 7's.

170's in a 10in circle @ 40.

Rem 870's/ Good success with the old Hastings non-ported chokes in 12g and 20g.
