I just shot the first 10 rounds I loaded, and I am amazed. I think I may be running the bullets a little bit slower than I was with W 231, since I was just guess-timating my loads with it.
This stuff (Clays) is incredibly soft shooting and it appears substantially cleaner than 231. It almost felt like shooting a different gun. I am very excited. I feel like an Israelite who just came out of the wilderness after 40 years.
