Johnny, I don't have and have never used a Lee loading manual. I think I bought one a few years ago and decided some of it's loads were a bit more "risky" than I wanted to play and tossed it in the trash. If your experiences with it are different and you trust it,great.

None of us can dip any deeper than our experience. I'm surely not anti-4198. I've used it with great effect in 222 222 Rem Mag and the 223. And I've had some good cast bullet loads for it in my .458 American. It's a good powder but certainly too fast for many uses.

I got out all my reloading manuals, Speer, Lyman, Nosler and Sierra. NONE of them have any loads for 4198 in .308 or 30/06.

Here is a quote from my latest Speer Manual about 4198 and my experience with it certainly backs it up.

"A single-base cylindrical rifle powder for 223 Remington class cartridges. It is useful also in large diameter straight cases like the 444 Marlin, 45/70 etc. 4198 can be used for reduced loads in other cartridges where noted."

Sure it can be used in mid-sized cases, but with most of them you'll peak out on pressure way before you reach optimum velocity. But why use it when there are other powders better for the job...at least in the cartridges we are discussing?

Hunter, I guess you could say this is just my opinion...and apparently the opinion of the vast majority of loading manuals as well. To my knowledge I've never used 4198 in 308 or /06. I have used MOST of the other traditional powders in both cartridges and with virtually every bullet weight there is. None of which should ever be construed to imply that I know everything. I'll be the first to tell you I don't.

If you guys are having wonderful results with 4198 in .308s, I'm happy for you. It just would not be my advice.

Good hunting!
