The Roster article on p.40 says that improved modified and full or tighter and shot size 4 or larger exacerbates choke problems with any hard shot. So if I read the article correctly, he advises against shooting steel or any hard shot through full chokes.
I think that directly affects Parker shooters now, because I have often seen advise in this forum to use high antimony hard shot in full chokes for maximum pattern effectiveness. Roster also cautions about using buffered shot loads as they can cause gun damage, and i know people here have talked about using buffered loads.
Also, interestingly , p. 38 " steel and other hard, nontoxic shot types are fully contained in plastic wads specifically designed to protect against the shot coming in contact with the barrel throughout its length. "
All very interesting , to me at least, and I like learning about it. I'm not an expert in designing shotguns shells or a consultant to the shotshell industry, like Roster is. I always wish I knew more and could do extensive testing and development like Roster. I read some of the things he is writing about in a private shotshell industry letter a couple years ago, and I am very glad to see this finally in public print. He doesn't specifically address vintage guns in this SS article and I hope he will at some time deal with these issues like he has privately partially mentioned in the past. I think its fair to say that this issue is mixed and provokes strong feelings from some. Roster talks about "rumor and misinformed hearsay" p.38, and maybe investigation can continue. I recommend the article to those who are curious about these details.
