38 special and the Uberti short rifle in .357?

[McCrower]

I recently ordered a brand new and pretty expensive Uberti 1873 short rifle in .38/357 and I really look forward to using  and reloading 38 special for this great gun.

But after reading some posts on forums here and there it seems like .38 doesn't work properly in this rifle. Is this really correct?  Do I have to modify my new rifle on arrival?

The ones we use at work shoot .38s just fine. The Marlin is a little finicky. The '92 is a lot finicky about AOL.

The '73 only has a problem if the ammo is too short (or too long, but that is not usually a problem and especially not with .38).
In the following picture, the stubby round on the left (90 grain bullet) is too short to feed in the '73 but the others feed fine.  It has to do with the ramp on the front of the brass carrier block.  Pettifogger has a nice tutorial online about how that works and how you can determine the needed length of your ammo, but I don't have that web address handy right now.  But most cowboy ammo works fine.

Abilene: Thank you very much!

You're welcome.  Found the article:

By measuring the length of the carrier from the rear to the point where the ramp starts will give you your minimum OAL.
