3 inch target at 100 yds 10+ winds with new CZ 453 American 22lr and weaver t-24 i just picked up. using eley sport ammo. 10 shots fired. Not bad for a brand new gun.Hopefully will get better after 1000 or so rounds.

NICE!  How did you keep the dime from flying off the target when struck?

I think all 3 shots were fired at one time.

3 round burst 

^^^ first shot went thru the dime and flared out the back to grab onto the cardboard. cardboard is the thin dense type like the old cardboard that the range used to use.

5 shots at 100 yards w/ el cheapo DIY Shoot - N - See target.

50 yds at kokohead  bipod only.  Savage mk II with eley sport 22lr ammo. windy day out. weaver T-24

Raining and had to stop

100 yards

223 Savage Axis

Dang picture needs to be rotated it's sideways

Using my 22LR Rim Measuring Tool I figure I would do some test shots.

Federal Auto Match 22LR
Gun: CZ455 & 50 Yards 10-15mph winds.
Waited on each shot for the wind to die down.
I will do some more testing this weekend with a more scientific approach

I am surprised that the Federal Auto Match is between .039" to .044" with the Majority in the .040" to .043" range. Best grouping is .042"

Lapua Match ranges from .038" to .046" best grouping is with .042"

Not to be a buzz kill but unless you are in an indoor range with no wind and clamped down in a vise  it's impossible to due any comparison with accurate results for something like this.  I mean you can tell differences in  between good and bad ammo. or ammo you're gun likes outdoors with some wind,but subtle differences in rim diameters takes specifics that just can't be done in that situation. I'm assuming you are talking about the grouping sizes in the picture you put up ?

Considering that .22LR headspaces off the rim, and that .22s can have as much as .055" of rim space (especially if the bolt face hasn't been de-burred), and that facing a .22's bolt to bring the rim space down is a time-tested way of improving accuracy on semi-auto .22s, it is certainly plausible that selecting rounds with the same rim size will allow the bullets to enter the throat more predictably, giving you substantially better accuracy.

Beg to differ.  Even out doors in the wind, you'll be able to tell what ammo your .22 likes the best.  That CZ ought to be putting them near in one hole at 50 yards with the ammo it likes.

I have been playing with this for a few weeks out at koko head.  I have done random ammo tests and grouped rim size test. And my results have been pretty consistant.

I understand the wind to be a factor. But just gotta wait till it settles.

I did say you will be able to tell the difference in what ammo your .22 will like if you read it. I said for checking other small differences you need a controlled environment and a gun vise. Exact repeatable shots can't be done with wind of any kind period. We can just agree to disagree I suppose.
Also 1 group of 5 could just be luck. Most like to see results just like any ammo test 3-5 groups of 5.

 

Back to just posting targets preferably.

Damn good shooting Knocker, and everybody else for that matter. 

Reviving thread.

5 shots at 50 yards. .17HMR Savage FVSS. Bought used from Eugene.

Best group I ever shot.  Flyer was the last shot ( of course )

Now posted on outdoor mini-fridge. 

Nice shootin' Tex
