measure rim on 22 ammo

45dave · Post by **45dave** » Sat May 10, 2008 8:56 pm

Long ago I remember gage you could buy to measure the rim on 22 ammo to seek similar size rounds. I was wondering if anyone in here currently measures and sorts there ammo for rim thickness, over all length or some other key feature to help minimize flyers.

Thanks

just to "learn" without going out and buying some specific ( EXPENSIVE )
gizmo... just get some .223 spent brass at the range
and find a few that are NOT bent or "nicked" ...

and notice that your .22 rimfire ammo will go into the .223 neck
nice and neatly...

go get a basic caliper, like: http://www.harborfreight.com/cpi/ctaf/d ... mber=93293

and measure the .223 brass from base to neck...
THEN with your .22 ammo inserted, measure again...
voila!! the difference is your .22 RIM-SIZE

sorting ammo by rimsize can help you find some that behaves
better/worse in your specific pistol...

tie a rope around your waist when you do this...
you may be in danger of slipping into the "dark side"...
there are a LOT of very subtle aspects of ammo that can be
measured to identify "consistency"...
but I'm a LONG ways from being consistent enough for the
ammo to introduce variations in my shooting...

There was an article a couple years ago in ShootingTimes
about Eley ammo mfg... and they had taken it to an extreme
( one ex: tracking the humidity at the assembly-facility
where the .22 ammo was mfg'd )...

edit: found it:
http://www.ShootingTimes.com/ammunition ... index.html

Others can contribute their experience/perspective...
but sorta-generally speaking, .22 ammo prices reflect the
Quality-Control used in the mfg to produce consistent-ammo.
A bulk-box of $15 (and rising) Rem/Fed ammo is fun for plinking...
but some of the $15/box !! for Wolf/Eley "should" get you some
ammo that is very-consistent...

Some of the "well experienced" shooters will order multi-cases of
Eley ammo that was all run on the same "machine-ID / set-up"
and have enough to last a few years of practice/competition with
their prized target pistol(rifle)... and have the grip/stance/trigger/etc
refined to a level that the ammo needs to be as consistent as they are.

enough... you other guys chime-in here and pull me back!!!

I think the gauge is still out there if you look hard enough.

I remember articles a long time ago. If I recall correctly, the results were mixed.

If you are shooting a rifle sport where the last .001" counts, a rim gauge might help. For the rest of us, the time spent with a rim gauge would be better spent in practice.

I think you're a bad influence on "Bear"...
You should be following his example and go chase a cat or car...

Now you got one of his favorite sports, chasing cats and the only car he chases is ours, we never leave home without him. He is our American Express dog. Hope he never catches the neighbors cat or I will have to do a burial detail. A few years ago we were up North and he got hold of about a 10 pound coon, that coon lasted 2 shakes and never moved again.

I'm glad to know that someone in your household is getting some exercise.

I have the "lo-tech" variety described by toy! It's a bargain and it works!

Stoney Point made this one!
