Uh oh!  I'm running into a problem with these cases that I hadn't anticipated, rim lock!  This is at an OAL of 3.023" with the Hornady 150gr FMJBT.  It's sometimes happening in my chargers and they're jamming up. Once it carried on through into the rifle and the top round was locked.  I'll experiment a bit more with them, let you know what's up.  Could that bevel on the rim of the Krag case help them self sort better?

Oh now I remember!  I had to do some tweeking on the chargers to get them to feed the 311284 loaded a bit long.  I've been un-tweeking, and they're working better.  I still need to be careful how I load them.  With Paul's you can peek in the back and see if they're in there right, each with the rim ahead of the one above it.  An old one I made that doesn't work as slick as Paul's, is loaded from the top, so I can see the rims go in right.  Some of my tweeking pulled some solder loose at the top of Paul's, where the shoulder of the top round is usually stopped with the cartridges just the right angle to keep the rims aligned.  I'll have to get that fixed.  Mine never did work as slick as the Parashooter design, so I use it for the initial loading in rapid fire.  I have a sheet of brass coming to make myself a few more of Para's design.  I tried some aluminum sheet, tabs didn't last long with printing plate, and some other sheets I had would break when bent tight.
