H4831 vs IMR 4831

[Nooch13]

so I'm working up a load with what I have on hand for my 300 win mag. That is H4831, brand new hornady 300wm brass, cci large rifle primers and Sierra 240gr BTHP. My Sierra manual only covers IMR 4831. I'm pretty sure the H4831 burns slower. Does anyone have data on it???

Haven't ran the 240. Have you looked the Hodgon load data below?

I saw that with the 230. Actually found the data in my other Sierra book...I'll post a link shortly

I really like h4831SC in my 300wm for up to about a 208 a max. Looking at the data, it looks like you will be hitting pressure with low velocities. I think Retumbo, h1000, RL26, or 7977 might be a better choice for 240s.

I wanted h1000 but couldn't find any. I'm totally new at this so I don't have stuff laying around yet! Lol
