Paul,

I'm trying to confirm if its IMR 4350 or H4350 at 40 grains and a 220 grain RN FMJ bullet you're using. I only see loads for this projectile with H4350 in the various reloading manuals and websites I've seen.

If it's IMR 4350 I was just curious where the load is actually published so I know where to look. Also, is there any real significant difference between shooting 40 grains of H4350 vice IMR 4350 besides what I would assume would be a slightly lightly lower pressure with the H4350?

I'd like to replicate the characteristics of the original .30-40 USGI round as accurately as possible while also keeping pressure down to as low as possible to give my limited brass stash a break.

Thanks again.

Stretch
