I tried it in my Rem700 with Hornady 168gr match bullets and could get it to shoot ~3/4" @ 100yds with 46gr with regular CCI primers. I went up to 47gr and got stiff extractions so pulled my loads with 48gr without shooting them. I have a really tight chamber though so you may get different results.
I didn't have my chrony out that day but was still surprised by the accuracy. It's still not the best as I can shoot around 1/2" with H4895.
Still had copper fouling in my bore. Wasn't noticeably better or worse than when I shoot H4895 or Benchmark.
