I have been having a lot of NO fires from my Armscor 357 158 GR FMJ
I have been shooting my Rhino 5 inch with Moon clips.
Today I took the time to do a double strikes.
Only 1 fired on second hit.
I examined the primers.
All hits were deep.
DA! Good idea. I will swap the moon clip cylinder into my Rhino 4 inch and see what happens. I will also run the course with speed loaders with my NON=moon clip cylinder.
Some times it just takes someone not totally involved to have a good idea.
I had bogus(squibs and no fire) 22lr and the 357 if I recall. Small batch of 9mm ordered by mistake has been ok. I wont be buying Armscore anything anymore.
I have shot their 45 acp in the past with good results. It's not anything I would compete with, but seems fine for plinking. You should contact armscor and complain, they might try to make it right.
