New CZ 457 bolt super tight when closing

[Mysticprecision]

Thanks again for everyone's thoughts and ideas, this is such an amazing community!

I'm going to try some different brand ammo as everyone has suggested, and work my way through there. Even though I thought I scoured all the message boards, I'm finding more and more and more posts about the same thing now all of a sudden, grauhanen, thanks for the links!

When cycling the bolt without ammo it feels easy, but with ammo is when it's hard to close it. One thing I did notice was with the CCI SV, some felt easier to close than others, so it seems to line up with ammo consistency being the culprit.

Just wanted to make sure I wasn't causing damage, but if tight ammo is the case, should I stop using this ammo altogether?

Try and get some SK, Lapua or Eley ammo and give these a try. Maybe you already have a 'match' setup and can live happily ever after shooting quality match ammo. A few rds is all you need to figure out what is what

US branded stuff can have some heavy rims or wondering QC so I wouldn't suggest there is anything wrong with the rifle yet.

If it functions well on match stuff, then you have got a great set up and saved some hassle and addn costs trying to shrink headspace later

Enjoy
