So far, I've only tried AA2230 with the 175 MTH. At first I thought it would be good as initial groups were fine at shorter distances. .5"-.6" which is not impressive, but workable. I was using 50yds on that day due to range limitations. Once I started shooting them at 100, they gave me fits. I intended to use them elk hunting, but decided to shoot six different loads in one session and pick the winner for elk season. The MTH wasn't even close... Velocity was great at 2889, which was not a max load but had shown the greatest potential early on. Started to feel a tiny bit of a stiff bolt at 2940. I too assume the BC is not quite as advertised, but even if quite a bit less it would still be impressive. I intend to play with them more and find some accuracy. Being limited to 2.82 to fit the mag can be a challenge though.
I may try to seat deeper and then try 8208 as it does well with lighter bullets.
