Not the cartridges you asked about but close ,
3246 fps with 98.0 gr of RL33 was a hot load and blew the 220 gr ELD-X bullet into pieces, vaporized 3 water jugs and most of the bullet, 90.2 gr of jacket and lead fragments were in the 4th jug,
best accuracy was with 96.5 gr of RL33 for a 3 shot ave at 3172 fps with no pressure signs, (pressure signs appeared with the 97.5 gr & 98.0 gr loads) SD was excellent and is a clear indication of a good node to start playing with, after shooting the 212's and now the 220's it sure looks like the ELD -X bullets thrive on peak velocity for best accuracy, at least in the 300 LRH case , due to the extreme bullet expansion (blow up) with the 212's and 220's, I won't be loading the 200 gr ELD-X in the 300 LRH and relegate those to my 300 Win Mag and 300 WSM rifles for testing
