Who owns a CZ MTR,or an RAP?

[Harpoon1]

I use 10 rd ASC mags.The only mags I ever used and I’ve never had a problem with them in any of my Grendel rifles. But the only bullet I shoot are 123 grain Hornady ELDM and 120 or 123 grain SMK.Hand loads only.
Only problem I have had which I posted around a month ago was that the bolt would sometimes get stuck after a shot. Not to where I had to use a mallet. I had to hit it with the palm of my hand and work in a bit to get it to open.
It did it four times in the first hundred rounds.I cleaned the barrel and the bolt functioned well. But through the next hundred rounds I had the bolt get tight on me a few times after shots. Not stuck tight, but I had to work it a bit to get it to pull it back.

Roger that, thanks.

Guess I’ll have to give the ASC mags another chance. Run C Products and Elanders almost exclusively in the gas guns and saw little reason to change in the bolt guns, maybe that’s been my problem all along? That and lighter, shorter bullets.

I’ll let you know what happens. I sure would like to get to the bottom of this!
