I'm wanting to work up a load for the 150 gr ttsx in a .300 win mag, but I noticed that the barnes website only lists data for H4350 and not IMR 4350. I only have IMR 4350. I noticed that every load I have ever seen shows the max and starting loads are between 1.5 and 0 grains different for the two powders with H4350 allowing slightly more powder.
Would it be safe to work up a load normally with IMR4350 using the numbers for h4350 and stopping 1.5 grains short of the max load listed for h4350 (73 grains)?
If anyone has a load for the .300 win with 150 ttsx's or tsx with IMR 4350, let me know.
