Just checked on Barnes website to view their load data, turns out most of the manufacturer's use faster powders.....they list at Barnes RL 7, AA 2230, IMR 4198, Benchmark, & X-Terminator.
I'll stick with what they have, my Hornady manual isn't up to date on the 338fed so i'll have to go off what i find and work my way up slowly.
Can anyone explain to me why for this round the factories are loading it with faster burn rate powder's, when other 308 based bullets use med to slow for heavier bullets? Like the 243, 7mm-08 & 308 will use med to slow.. Is it because the neck of the case mouth is wider so there wouldn't as much pressure on the brass??? Still doesn't make much sense to me but i'm sure the engineer's that write the data know what their doing. Just need a perspective to understand it better. Or how the barrel channel is wider so the slower powders can't burn as effectivly. So the faster powders would maximize the use of space to burn before the space is to great to fully ignite?.......lol, i could go over it in my head and visualize but their just educated guess's
