I'm considering the purchase of a CZ 457 MTR but as we all know those rifles are in short supply. A dealer that I have emailed has a 457 Varmint in stock that I could readily purchase. So my question is regarding the accuracy potential of the Varmint vs. the Varmint MTR. It appears to me that the major difference is the how the chamber is cut on the MTR. I'm hot a huge fan of the stock on the MTR but admittedly have never even seen the gun in person and for bench rest shooting the oversize pistol grip may be preferable. I'm also reading about difficult chambering in the MTR. Any thoughts appreciated.
