Insanely impressive! I get clover 5 shot groups with all 3 all day long but I am a fanatic with load work-up to the 1/10 of a grain and weight sorted fire-formed brass.
I use 168's, 190's and 215's and all of them are really impressive. I shoot the 168 at 500 on calm days, 190's on windy days and the 215's to 1000.. The BC of the 215 VLD's is close to .700 (.696).. very impressive. I used a Serengeti reamer on my build so the 215's are the max you can use in that chamber without shoving 3/4's of it down the case but you really do not need to go heavier. That bullets does anything I want it to do on top of a bit slower powder like 4831, VN160, or Reloader 22. H4350 for the lighter weights.
I also have a 28 inch barrel so that helps with the velocity and gives me leggs a 22" doesn't have.
