RCBS will replace your parts for free. Have dealt with them many times. They never ask any questions, they just ask for your name and address and send out the part.
Ran some of these thru my 18" PA 10 the other day with RE 15 and TAC. 43.6 gr of RE 15 produced just over 1" at 100 yds. 42 gr of TAC did well too. Still need to fine tune the loads this weekend.
