I was in Walmart today and noticed they had 2 containers of T7 2F powder on sale for $15.00. Now I've never used T7 before but I thought I would give it a try in my Knight 85 inline with #11 DN caps. Now my question is this; Will I get the crud ring with 11 caps? From what I think I read here it is caused by 209 primers is that correct? Is there anything special I should know? I only got 1just to give it a try.
