Im not so sure it the knurling the SMLs dont like, i think it was the sharp base to side transition mostly or slight boat tails. Very few BTs will shoot at higher SML speeds. The Bloodlines appear to be more rounded in that area. The Lehighs also do come out a slightly larger loaded OD in my sabots from the kurling but not bad. If the NULA doesnt like the 275s i should have no problems using them in the 54cal and buy some Bloodline 250s to try instead.

I would really like to try some of the Lehigh 40-200s with a similar base as the Bloodlines since Knight doesn't sell them
