they are accurate and do create LESS crud ring than T7. Its going to really depend on your primer.
I think if you use the low temp winchester 777 primer, crud ring should be no issue at all. With the Winchester W209 "blue box" i got a crud ring and while it was soft enough to push through, i could get roughly 4 to 6 shots before i had to swab the bore clean.
