Max OAL on .357 with RN bullets?

[23 Blast]

Had a question regarding maximum OAL.

Was reloading a batch of .357 Magnum ammo using 158 grain, copper plated bullets (no cannelure groove)

According to the reloading handbook I have (Lee's 2nd Edition) - the max OAL for the cartridge is 1.590". When I've loaded with these round-nosed bullets, and seated them to where the case mouth is right at the point where the straight sides of the bullet curve toward the nose, the OAL measures 1.64". I've dropped the finished rounds into the chambers of my Blackhawk cylinder, and they fit fine (the bullet noses don't protrude past the front of the cylinder).

The diagram showing measurements of the cartridge in the handbook depicts a flat-nosed bullet. So, am I OK with a slightly longer OAL? I don't much like the idea of mashing the bullet further in, I don't think it will crimp properly.

You'll be fine with a longer COAL as long as they function in your gun.

That is the only criteria that counts with a revolver. Use just enough crimp that the bullets don't move forward during recoil.

Yep, the max OAL will be what fits your gun. However, if you run at max, watch for creep so you may want a crimp.
