OAL

So I am finally going to get to the load workups for our project Mosin because we need to get it on TV. We hit the airwaves in January.

I got the case for the OAL gauge from 0933, slid in the 174 SMK and by the time the round hit lands, the bullet was so far out, the boat tail is sitting so far out of the case, it is grabbing air.

What am I doing wrong?

Sounds like you have a long throat or one that's tapered...

It means the barrel is shot out. As a barrel ages the rifling get eroded farther and farther down the barrel and the bullet then has to jump farther and farther. Its time for a new barrel.

Another remedy would be to have the chamber set back an inch. This will buy you some more life out of the barrel.

I thought it was a built rifle, with a new barrel. I bet it has a tapered throat. Or it could just have a long jump. Either way you'll be ok with SMK. They are not very jump sensitive. Seat them so you have about a 1/4" of bullet in the case then just tune the powder charge. After you tune the charge you can play with seating depth some.
