Very good explanation.
Thats about the way I "develop a load"
Load 3 of each charge starting a couple grains less than I know is too low.
and load .5gr or whatever until 2 over than I know is too much.
Fire and inspect each case as it comes out of the gun.
I learned a nasty lesson with that NEF build of .17 VR.
Just because one fires fine don't mean all three will.
I shot ten times with the same 10,0 gr, same case.
upped it to 10.1, just fine 3 times. upped it to 10.2
and blew the gun up. All with the very same case.
I used the same case to make sure there wasn't any
case difference to bite me.
That time I got mighty lucky as only a few small parts were broken
and just a few tiny spots of blood on trigger hand from
the plastic trigger guard coming apart.
Parts broken were: firing pin, extractor lever and trigger guard.
It's mighty handy having a bullet trap in my shop. Much closer than
the 13 miles to the range. OF course I live alone too.
