Thread: CZ 17 HMR varmint accuracy issues...HELP PLEASE!!!

I have the above rifle, it is shortened, suppressed, bedded and normally an absolute tack driver with hornady 17gr ammo, it does copper foul and the accuracy starts to drop off after 100 or so rounds.

I recently lent it to a mate with a rabbit problem, I also gave him a rod with patches and boretech eliminator, hoping he would occasionally clean it!

He called me recently and said the gun wouldn't shoot, I picked it up and gave it a really good clean, the best I could get it to shoot was about 2" at 50 yards!

I stripped it completely and thoroughly checked and cleaned everything again, I re shot it and even tried the 20gr ammo that it didn't like years ago when I tried all sorts of ammo to find out what it liked, no joy, it is still only shooting about 1.5" at 50 yards.

It has a vx3 4.5-14 on it and Burris z rings on a piccatinny rail, everything is solid.

The only thing I haven't done is shoot it without the suppressor.

HAS ANYBODY GOT ANY IDEAS WHY IT WONT SHOOT????

It was normally a 1/2MOA gun and I could shoot inside 30cal bullet holes at 100 yards when mates would sight guns in.
