Thread: 17hmr

I bought a CZ 452 off a feller on here 2 years ago. Took it to the range and it shot like this.


Have not done anything with it since but I pulled it out and scrubbed the heck out of the bore last weekend and might go shoot it Saturday with all the ammo types I can get locally.



E: clearly this is appalling precision, my Q above is looking to see if 10xrd 1.5 moa is a normal and realistic expectation, or is it 10xrd 3moa, to know when I've got it "sorted"

Scope?? Had 22 that looked like that until i changed scope. Only reason i say that is theres no real pattern of spread, just drifting sideways

I had a very similar result with a 455 .17HMR with multiple ammos and different good scopes.
Turned out to be the suppressor, it wasn't striking but must've had some weird harmonics because as soon as I tried a group minus the suppressor, it shot perfectly acceptable.
