Cz 457 Varmint MTR

I compete against 457 MTR's on the 50 yard IBS score targets with my 457 Varmint 20: barrel. Those suckers really shoot. I can stay with them in conditions but when the wind don't blow they are good for 248-250 and I peak out at 246.

Thank you for the information, usually people just say competive. Its nice to have a numerical definition of how competitive.

I am Dave.....I figured If the rims were consistant, The headspace would
be the same for each batch. I'm also thinking that an overly thick rim
could hinder ignition. I've yet to shoot them but I sorted 500 Wolf Extra
match and the spread was as much as .005". Oddly, the sort size was
pretty even with the edge going to the thicker side. I may chrono the
high against the low to see if things shake to that end.....Always something !!
Since you sort for rim thickness, do you shim the headspace? If changing headspace do you set it to match rim thickness? Example ammo is 0.0415-0.0425 shim headspace for 0.0425?
 
Ok guy's, I know it's been out a while but wanted some opinions on it before I make the purchase. Will it be good for local club shoots from 50 yards to 200 yards? Shooting usbr targets mainly. Optics will be a Sightron 45×45. Ammo will be lapua center x as long as it likes it. Front rest will be Caldwell Rock BR and edgewood rear bag fill with heavy sand. Thank you for your time.

Offhand shooting? No, those are not shot offhand, thank goodness! We are allowed to use club provided front bag or shoot off your own bipod. No back rest is allowed. You can use your hand to help study the butt stock, but it is not allowed to touch the bench.
 
most CZ's like pretty much anything SK. Mine like Pistol Match Special, Biathlon and Long Range Match. SK seems a lot less lot sensitive for me than Lapua or Eley
Isn’t Lapua and SK both manufactured by Lapua? I was told that SK is Lapua that didn’t test well enough to be branded Lapua.

Sounds like a winning combination to me. You will need to fix the trigger for max accuracy potential though. You can get a 8-10 oz trigger with just a spring change. Noting that this is an older thread so hopefully the OP is already there.
 
Did you ever chrono these? If so, I would love to know the results.
I did a 20 shot sample of each rim thickness on the Wolf ammo.
The thicker rims did not group as well with double digit SD's.
The thinnest rims shot the best with single digit SD's. I repeated
that test with the remaining "Remington target" ammo. Surprisingly
there was on difference, although both high an low rim thickness
both showed double digit SD's.......

I have a theory.....The thicker rims keeps the bullets short of the lands
and the thinner rims let the bullet get deeper into the bore. We are
talking in some cases, .000" to .007" difference.....I'll note that the thick
rims give my bolt a much harder close.
 
Is the MTR comfortable to shoot left handed. I can't find one to put my hands on so can't honestly tell from photos.

Thanks

I mispoke. What I should have said is Lapua tends to be more lot sensitive for me. For some reason almost any lot SKS PMS shoots sub MOA, also the Center X tends to shoot better than the Midas +
 
My 457 Likes both SK Match Rifle and Lapua center X. We shoot 100 yard and it does well. Hard to beat those with the high dollar anschutz and such.
 
I'd have no problem putting one in a chassis, and probably will
with the way I do things. Being in a v-block with solid mountings
for the screws, you really can't go wrong. Companies like Voodu
build on chassis with their rimfires.
