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!!!
