Not yet, I've been shooting Hornady ELD-X & M's in the 140/ 147gr class along with Nosler 140gr PT's...
53 to 54gr of H1000,,, 2880 ft-per seconds...
My back up powder is H4831,,, 2770 ish ft-per seconds,,, i wish I could get my hands on some RL powder,,, but its very rare up here in the north... i did a short
Tap it cool with the 4350 since it goes from a ok charge to hot very fast. I've melted a few cases testing the 4831 and 4350...
Others will chime in on their loads I'm sure...
And yes,,, H4350 will work,,, your rifle & brass will let you know when you reach max if your trying to find the fastest load...
Again,,, keep and eye on your brass,,, watch your primers and the edges of the head melting deforming at pocket or pin extractor...
Cheers from the North
