    Mod. 14-3 cylinder blow by

    Never mind, I just googled it and figured out what the "forcing cone" is. Thanks to all.

    Mod. 14-3 cylinder blow by

    Thanks for all of the information and ideas about what is going on with my K38. As a result, I guess I just won't worry about it any more. But, I am curious about one thing stated by epj above. What is the "forcing cone"?

    Mod. 14-3 cylinder blow by

    I read in several places that .38 specials, and perhaps other revolver ammo need a "tapered" crimp, not a roll crimp. The die set I am using is a roll crimp the more you crimp it, that is why I mentioned that I might lessen the crimp to decrease the roll, then shorten the COL slightly to...

    Mod. 14-3 cylinder blow by

    Me too. I wonder if somehow the cylinders have gotten out of perfect round somehow, causing a little loss of pressure when fired. The gun is well over 40 years old, and although it hasn't been shot much in the last 40 years, I can't remember how much I used to shoot it back then.

    Mod. 14-3 cylinder blow by

    With that in mind, perhaps my "role crimp" is too tight. In order to remove a bullet, it takes me 2 good raps with my removal hammer, so If I lessen the crimp and decrease the COL slightly to compensate, perhaps the case will expand more and seal it off. But, that doesn't explain why the...

    Mod. 14-3 cylinder blow by

    Mod. 14-3 cylinder blow by

    I started using hand loads, 125 gr. X-Treme plated flat nose with Titegroup. I started with 3.8 gr. and worked my way up to 4.8 gr., trying to get the fps up to the 900-1000 range. All of the powder weights had the same blow by/powder burns in the same place. I then bought a box of Sig Sauer...

    Mod. 14-3 cylinder blow by

    I have a pre 1980 Mod. 14-3, and am getting blow by (powder and burn marks) on each fired shell and in each hole of the cylinder toward the center part closest to the pin which it revolves around. Any ideas on what could be causing that?
