what says you, good or not, safe to shoot magblends thru a lead only ultimag choke :funnyturkey:
The lead only stampings are for large steel shot, not fine hevi shot. Totally fine to shoot.
I used to use a comp n choke tube with hevi 6 and never noticed any problems with it. I have since switched only because I found something a bit better but it didn't seem to be an issue.
Have done it with a hastings imp modified for coyotes using hevi shot. Works like a champ, no issues whatsoever.
