Barrel Chop Screwed Up Accuracy

[kevlar88]

Any update on your CZ’s accuracy? I’m curious. Years ago, I ordered a .17 Hornet 527 from CZ and asked them to cut and thread the barrel. They could never get it to shoot well after the chop either.

I was finally able to pick up some cfe223 locally to try a different powder. Unfortunately life is currently getting in the way and will probably not get to shoot again for another 3 weeks or so.

The gunsmith wouldn’t take ownership of it. Ended up taking forms advice and going through everything and checking it. Last thing I got to was re-torquing the barrel. I bought a barrel vise and action wrench and cranked it down. It was pretty loose turns out. I went to 120ft/lbs and now it shoots like it was before. Never using that smith again.

Did you ever get this figured out? We didn't get a conclusion to your post.

Awesome! Glad you found your issue. Sucks that your issues came from the gunsmith.

CFE still wouldn't make the barrel shoot, it's FUBAR. New barrel incoming.

Do you still have the barrel? I'd be interested in playing with if you're getting rid of it. Please let me know.

I do not. I sent it off to my machinist as part of another experiment to see if he can match the chamber and action threads without sending in my action. I'll have some answers, to if that works or not, in the next month or so.
