I have an Indian creek .555 in mine and I'm very happy with it. With Federal #9 tss it did 318 in the 10" at 40 yds. It also patterned well with longbeard xr #6 with 157 in the 10" at 40. I'd say you won't go wrong with the Indian Creek, a Jebs, or a Sumtoy but the IC is the only one I have experience with.
