Just got done trimming 250 Herter field load hulls (Cheddite) back to 2 9/16 for my old LC SMITH 16 ga Field grade. they were 2.71" to start and 2.5625" trimmed. I figure I'll roll crimp them or do some experimenting on using a Tyvek patch or overshot card to plug the hole in the middle without shortening the overall length of the loaded hull. MB
Try the Hartin crimp with an overshot card.
