My CZ 457mtr is amazing, 10 for 10 at 325 yards

[Jesse_L_B]

well I was out playing at some distance yesterday, shot my new mtr farther than I have ever shot a 22lr. I have a video showing 10 hits for 10 shots at 325 and even managed to sqeak out 3 hits at 400.

Cheers
Jesse.

Nice! What optic were you using? Have you shot the rifle at 50 yards and if so what size groups can you get?

 

[Jesse_L_B]

I am running a diamondback tactical 6-24×50. It sits on a 30moa area 419 rail. With my 50 yard zero I am 4 or 5 mil from bottom of my elevation. I am able to dial 15 and a bit mil. Strelok says 13.77 mil, which was very close, so i was able to dial for distance and i had to hold 3 mil right for wind. As for groups at 50 i am very close to the half inch challenge. Just haven't put five in a row under half inch,close but not close enough.

Thank you.

Could you could run that gun and ammo over a good chrono or Labradar and get a Standard Deviation number?

What would a random SD number reveal?

What would a random SD number reveal?

I'm curious what SD measurement with his gun and ammo of choice, achieve the ability to hit that size target at that distance, 10/10 times. In some ways I'm looking for excuses why I can't do it.

I understand.

SD will vary by lot number. It can even vary by individual rifles of the same model. With ammo that can have a relatively wide ES as mid-range .22LR match ammo usually does, a minumum of 30 rounds should be chronographed to get a statistically meaningful SD in a particular rifle. Smaller sample sizes yield figures for which the confidence level in their usefulness is too low.

Whenever .22LR is concerned, wind is a key factor affecting accuracy, especially at long ranges. A little luck helps, and often the lack of it can be frustrating.
