I have a blast shooting my .22's, and predominantly use the local cheap bulk ammo: Remington "Golden Bullet". It seems there's a bit of powder charge variance in the bulk packs, some rounds sound almost squib-like, others have some extra oomph.
It's frustrating when you think you got everything zeroed in at 50 yards, and go to fire at a target and your shot is an inch or so high or low. Not quite the shooters fault because the report is clearly different from the majority of the group used for sighting the rifle.
So, I finally got a bright idea: I'll weigh the cartridges.
I grabbed a handful (14) out of the box I shot from today, and got out my Hornady magnetic scale and weighed them up. This is what I got:
50.0 gr - 1
50.2 gr - 1
50.3 gr - 2
50.5 gr - 4
50.9 gr - 1
51.3 gr - 2
51.6 gr - 1
52.4 gr - 1
I was anticipating some variation, but 2.4 grains out of a handful of 14? I think I'm going to pull a bunch more out and weigh them up, and take a handful of the same weight out to the range tomorrow.
We'll see how it works out.
