There isn’t a lot of information on this cartridge and thank you to the few guys I reached out to for information
Listed is velocity collected with a Garmin Xero shooting both the 55gr Berger and 55gr Don Ussimeg with Varget.
24” Mueller 1-9”, fire formed brass, Federal 205m, .020 off jam.
It was interesting to me the the Berger was slower and basically a charge weight behind.
Only pressure observed was at 32.2 with slight cratering, primers still round.
Seating depth test next
