Say to get back to that YouTube video search "blue collar outdoors" a couple of NY boys putting out video on pattern testing tss Turkey loads. The shell was not a 3 inch shell.
The only loads I run through my 28s are just the plain 2 3/4 inch 3/4 oz of 7.5, 8s or 9s nothing fancy As I stated, I gave away 2 cases of 1oz loads. Figured my guns were built to handle 3/4 oz and call me funny. But that's what I run through them. No steel or tss. Guns were not built to handle those loads. (AYA#1 and a FAIR 702 Jublee)
