I have just been given a keg of XMR4350 and know to use Accurate 4350 data, however I plan to use this in my 6mm-250 (new build) and can only find data for H4350. I do have Accurate 4350 in GRT and have built a cartridge and chamber in the cartridge designer of GRT and measured case volume of a sized case, but don't have fired case data yet.
So far GRT is telling me that Accurate 4350 is equal to or a tiny bit slower than H4350. I do have H4350 to use known loads for initial fire forming, but not having experience with XMR (accurate) 4350 vs H4350, I am hoping someone could confirm these results are typical or, have used it in the 6mm-250 cartridge.
Currently, GRT is telling me that roughly 38gr of AA4350 would be about max charge and just under 3000fps with a 108 Hornady.
Thoughts?
