Re-sizing a cartridge

#1 · July 2, 2014, 11:41 pm

I am using a 550B, which I have had for years and I just LOVE.
Stupid question (I figure I should ask BEFORE I try it)
Please no remarks about why I reload the .380

My older .380 shells are all loaded at about .950-.960". I am noticing in my Sig P232, I have TONS of gun jams when I run this long. However, when I run at .940", she runs like a champ.

I have about 200 rounds sized at .955" or so.

Can I just "resize" them by manually putting them in the third "stage" and gently easing the bullet in to .940"?

Or should I just "bite the bullet" and pull them and start over....?

That's what I do. I run them back thru stages 3 (seating) and 4(taper crimp)
if I find any that are to long. As long as I'm not running close to max load.

No safety issues are involved in seating the bullet a bit deeper.
