Primers

[ArchAngelCD]

Neither of those guns should have any trouble at all firing any primer that is made. The CCIs ARE hard, but again, there is nothing weak about a K frame Smith and you should only have a misfire rarely due to a bad primer. Something has been altered in those guns. I used to shoot CCIs in my mod 10 all the time and had primers fail, but with a nice, big hammer nose shaped dent in the middle of it.

Just to add, I own an 1948 M&P and all the ammo it shoots is made with CCI500 primers, never a misfire. I'm mentioning the age of the revolver because it has one of the lightest and smoothest triggers I've ever shot and still no problems with CCI primers.

If you have put in new hammer springs and tightened the spring tension screws all the way, you should not be having any failures to fire with any brand of primers. You could have short tensioning screws so you might try putting fired primer cups under the tips of those screws.

I have this problem too in my 64 and 14. Both have new mainsprings and tension screws rung all the way down. Thank you for the great advice.

BTW, I use CCI500s in all my 38 reloads and they are seated underflush. I wish Wolff made extra power mainsprings for the revolvers like they do for auto pistols.

I don't know what I am doing right, but I have over 50 revolvers, and I don't have any that give me light strikes. I did a chrono/accuracy test awhile back and could not determine any difference in velocity or accuracy with a revolver regardless of what brand primer was used.

The one thing I don't do is put an aftermarket "light" mainspring in any revolver. I expect my trigger pull in double action to be in the 10-12 lb range, as long as it is smooth. I like to be able to trust my revolvers for reliability.
