CZ 457 MTR ammo?

[Chubbyduck]

I’m looking to see what ammo others are running for 100 yards in there 457 MTR I’ve been using SK RED,SK Orange,Federal gold std,CCI MM so far none of these have given me any consistent results.im using accu-tac bipod with a barrier on table,bags or ears on rear,Athlon 6X24X50 have action torqued at 20in/lb .AT 50 yards its getting consistent 1/2 groups down to one ragged hole with 5 shots ,at 100 she really opens up 1 1/2 to 2 inches and greater at times.

Try Lapua center x

Try some better (more expensive) match ammo.
CCI MM (minimag?) isn't known to be particularly accurate. SK red should be ok though, however different batch can vary a lot.

Do you notice the groups have vertical stringing in them? If so then chances are it's the ES/SD/inconsistent speed of the ammo.
That being said, 1.5" at 100 yards isn't bad at all, to get less than that you need to be using batch tested, high quality ammo.
Eley Match/Tenex, or Lapau Center X/LR/SLR is what I'd try, however you can still find that the rifle is picky between certain batches.

Hear a lot of 457s run decent with Eley Team

Using Sellier&Bellot 22LR club ammo and CZ455 I used to keep 30 mm groups at 100 m on a calm day.
Since it's a factory "plinking" ammo I consider this decent.
If you want better results you must find suitable match ammo

ELEY Team ran incredible in mine.

If you are still running the CZ barrel, I have found the best performance is R50 spd 331 or 332 and Center-X spd 329 and 330. The last target in my match is a 1.5 inch 10 ring and a .8 inch X ring and I have held that target at 150-14X and 150-12x with each of those 2 suggestions. Another guy at my local range went to the Lapua test center and came back with the best ammo was Center-X at 329.

We will give ELEY Team a try,From what I’ve seen most people are saying there 457 does NOT like ELEY but then again every barrel is different.I will also get test boxes of Lapua,Eley,RSW
Thanks

Sk Match or Lapua CenterX will usually produce MOA or better in all 5 of my 457's. Eley products have never run consistantly for me.
