Re: Why The Weight Variances In Wolf Match Extra?
i did alot of 22 ammo testing, different brands, etc. and have found that weighing helps group size, especially at 150+ yards, and backed up by shooting through a chrony for consistancy. it doesn't get rid of all the flyers, but greatly reduces them.
the rim thickness not only judges the amount of powder in the primer, but the overall length of the cartridge, as the thicker the rim, the shorter the overall length (acts as a shim) and the thinner the rim the longer the oal.
when reloading centerfire you know how variations affect group size and consistancy the same holds true for rimfires.
as manufacturing of the rimfire ammo has greatly improved over the years, rim thickness has been less of an issue, but can still lead to better accurracy when sorted none the less, and along with weighing, ensures that what you have in the magazine is the very best you can muster.
i will say though that the wolf ammo has the least amount of weight variance or range of low and high weights of all the ammo i've messed with including the really expensive stuff. i would have to believe that's why it is so good in so many rifles.
is it impossible to get every round to weigh the same?
IMHO probably not but it would be impractical, and expensive to accomplish.
the weight difference can be attributed to the a bunch of variables such as thickness of the casing walls, rims, bullet weight, powder charge, primer, etc., or even and most probably a combination of many of them.
don't forget no matter what the brand, they are still mass produced in bulk, which add to the charm and challenge of consistant rimfire shooting. but i have found that "weight lots" reduce the the amount of "drastic variances" and that in my opinion leads to better groups and accurracy.
