Checking ammo



Log in to see fewer ads
Will experiment some soon at a few targets.
And see what results are gotten.
Definitely can see some cartridges that are way out.
Used my crossbow bolt checker and a insert out of crossbow bolt. Allows bullet to rest on ogive.
Glued insert to frame of jig.
We’ll see if any positive results are obtained.
Also will shoot some of the longer and the shorter later on to see how poi is affected.
Likely will shoot at 50 yards.

I am allowing for some allowable tolerance. Some are .005” or more long and short though. Allowing for +- .002”
May change this though depending on results.

Need to see if my gun likes longer or shorter of the ones deemed way out of whack. Might be able to use whichever on squirrels.

Btw checked 2 different lots of cci.
One is better than the other as far as keepers based on my testing. Substantially better actually.

Wish I had a good modern crony.
Would be interesting to see if longer are faster on average and shorter slower.
Or maybe even vice Versa.
I know this much.
Every now and then my cz455 is noticeably harder to unbolt with some rounds fired? Like round has more pressure. Could this be one of the longer rounds getting more into riflings increasing pressure"??

Only one split case with this rifle lilja barrel setup out of around 700 rounds. It was a cci. Have shot some hornady thru it just not as much.

Have gotten just shy of 4 boxes of 50 (likes about 10 rounds) ammo that meets my set allowable tolerances. Took 6 boxes of 50 to get. Used 2 boxes of different lot number. It had more shorter rounds vs other lot I used.

May show some video with this project.
We’ll see. Need some light winds. And not be freezing cold. Trigger finger don’t like that at all.
