Not a gun writer, but I burn a lot of Ramshot powder. No comparison between the two IME. Big Game is much faster burning than 4350(H or IMR). Big Game is more like RL-15 class powders. Ramshot Hunter would be closer in burn rate(but not exact, so no substituting!) to 4350/RL-19 than Big Game.

In my experience Big Gsme is more like 760 or 414 in burning rate, a little slower than R15 but not much. Of course powders will swap places in burning rate when used isn different applications. I have also found Big Game to be cleaner burning and less temperature-sensitive than 760/414.

JB,
I find Big Game to be a tad slower than RL-15 as well, which is why I use RL-15 data as a starting guide when flying in the blind with Big Game. Then watch the chronograph. It most definitely is cleaner burning than 760//414....which is why my remaining stock became plant food, now that I use Ramshot. It's a great family of powders.

Well... Big Game is little roundish globs and 4350 is "rat turd powder"
Big game is definitely faster than 4350. It has NOT been my best Ramshot powder. I like TAC and Hunter better.

Big Game is to my idea in between, say RL15 and 4350. That makes it pretty close to H414 of course. I would say it is a little slower than H414 IMO. I haven't tried it yet, but it should be a great powder in the .375 H&H. One of these days I am going to try Hunter in the 7x57, it should be a good powder in one of those, but it'll be hard to beat H414.

I,'ve got a couple jugs of Big Game that I never seem to use, looks almost like it should give a good load density in .257 Roberts. Mostly just seeing data for 87-85 grain bullets. Anybody use it or have any good loads for Big Game and 100 grain bullets?? Sierra, ballistic tips, and such..

So far I like Big Game a lot for the 7mm-08, and in the .30-06. At some point I'll try it in the .22-250 and .308.
I will add, if for some reason I wanted the bulkier stick powder, then I could see 4350 in loads like .30-40 Krag, .303 Brit, for original rifles at moderate pressure.

The difference between Ramshot "Big Game" and H4350 is
My new answer is:
4350 is available, Big Game is not.

So all of the hoopla over Big Game with the sky falling due to its lack of availability applies to less than 1% of shooters and can be handled with a couple of patches of Hoppes? What am I missing?

Not much, I am pretty much done with anything Ramshot except TAC since there is no point depending on something that they can't get imported into the country no matter how good it might be. Best stick with something obtainable. At least St. Marks isn't held hostage by NATO.

I'm substituting CFE 223 in my 9.3x62. So far great speed and accuracy.

Yeah, a factory fire sure is inconvenient.
I'm a Big Game, Hunter, and TAC fan. Got enough of all three to last until volume comes back.
Big Game is great for 7mm-08, Hunter owns .30-06, TAC for .223.
