I pulled a bullet as suggested. It definitely appears to be RL50. It weighed out at 173.3. This is precisely within the charge weight range that was suggested to me by another member to match the factory speed of 2850fps. So that is good data.

I got some of the primed RUAG brass available through Barrett. Unfortunately it is shipped pretty loose and almost 1:3 necks were visibly not concentric or flat out dented.

Buy once cry once might be obvious to most, but I wanted to get something compatible with what I had laying around and got the Lee dies to work on my old Lee classic. Let’s say it’s doable, but not ideal. On the fresh brass I cut the decapping pin off the expanding unit to attempt to make everything more concentric without punching the primers. I bought a spare pin for decapping and sizing in one step in the future.
The Lee die resizes closely to the factory dimensions measured with a comparator. Though my fired brass visibly has a sharper shoulder angle taking on essentially a fire formed appearance. I’m thinking custom dies will be the way to go in the future.

Loaded up a couple of charge weights to try. The goal is ultimately to meet or slightly exceed the factory 500gr offerings, while maintaining accuracy, which has been really good in the factory loads (only tested to 500 meters so far).
The Lee seating die is also hard on the Hornady bullet, leaving an ogive ring mark, so that needs to be addressed too.

I’m going to get these shot, hopefully work up a load, then start stretching it’s legs a little bit further.
