416 Rigby with 300 gr. Barnes X and IMR4350?
In my Barnes reloading manual it lists XMR4350 but not IMR4350 powder. Are these powder comparable in load data? I am going to load up some 300 gr. Barnes X bullets.

Thanks wave

RIP
XMR 4350 is Accurate Arms or AA4350 formerly???
Powder lots change???

All the 4350's are close enough to start off at 10% reduction from a max load given for any of them and watch it as you work up.

If you are starting from scratch, go with H4350 Extreme. There is no better powder, IMHO.
