alot of the .17hmr ammo shoots extremely well, alot of people are under the conclusion that it is all manufactured in one plant according to a member on this website. I believe it just because of how consistent it shoots(I was able to achieve very similar groups from 3 different 17gr bullets. when i shot 20 gr i did have to re-sight a very small amount).

i would say expect 1 m.o.a. or 1" @ 100 yds if you do your part and there are no flukes. some shoot better, some shoot worse. still should be a ton of fun either way. Goodluck
