I'm loading bunny sneeze .380 rounds, 100 grain PFN from RMR, and I'm concerned about seating depth, not so much because of OAL itself but because of how little bullet bearing surface is inside the case once they are seated to the "prescribed" depth.
Here are the numbers:
OAL 0.980
.380 case 0.676
bullet exposed 0.304
So:
Bullet length 0.427
Bullet exposed 0.304
Bullet in case 0.123
These rounds pass the plunk test. I can clearly see the typical bullet bulge in the cases, and I can't press the bullets in by hand, so I'm not concerned about neck tension per se. The question I have is simply whether there is an issue with having so little of the bullet inside the case.
The rest of the load data: PMC cases, WSP primers, 2.9 grains W231 under the 100gr plated flat nose bullet.
