Has anyone tried IMR 4350 yet? That is what Bad-Bull use in their guns. Or could you use H 1000? Just looking to see what can be used and can not? A friend of mine asked me and I did not know so I thought that I would ask here. We are not using either powder just asking about it.

Per IMR website;
4350 is number one choice for the short magnum cartridges.
I read that as being way to slow of a burn rate for a ML.

Cuda, I've wondered the same thing, but even at Bad Bull's
recommended minimum load, I wouldn't load up a 10MLII
even close to that!
It may work with a duplex load. I'm sorta glad there is none of
it in my stock-pile of powders. ;D
Don't know about IMR4350, but of the powders tried, RL17 reigns
king for my short magnum as well as three others. Can't say
enough good about it.

I believe I tried it one time and it was way too slow!

Bad bull uses the IMR 4350 thier guns. Are thier barrels stronger than ours?

I doubt they are any stronger as far as steel but they may be stronger with the platform since it has locking lugs on the bolt. I think the plug is smaller in diameter, 9/16 maybe, like a SMI plug which would leave more steel in the area where the barrel threads are. Plus there is no barrel nut.
I believe their plug is shorter also, better ignition possibly and they use long barrels to burn that big dose of powder. I think Al tried 4350 in his Rem and the velocity was pretty poor.
Swinglock, Richards and BB all shoot about the same velocity with the 275BE, Bad Bull does it at lower pressure, "read somewhere it is approx. 50kpsi" but probably the most recoil with the long powder column.

4350 , way to slow and also is hard to ignite. Book tell you to use mag. primers in a cased load to get it to go bang!!

While not IMR 4350, I have shot a bunch of H-4350 out of my .40. Duplexed with 4759, it gave excellent accuracy, but was a little slow based on my charge weight (2,850 or so with 87-90 gr total charge).

Why use all that expensive powder and also mess with a duplex when you can get the same thing from 4198 (65 gr) and less of it. I use IRM 4350 in my 300 win mag, great powder but needs perfect conditions to ignite, it is much harder to meet all these conditions in a muzzel loader. You are also shooting a .40 a fairly rare ml cal and a 40 builds pressure much easier than a 50 or even a 45.

I guess because I can. Like most here, I experiment. If you can read b/t the lines, I stated it was slow for a .40 cal...... As far as the duplex comment:  |

I tried H-4350 in a duplex in my 40. Was quite pleased with the results but feared temp sensitivity. I think ewc or possibly Chuck41 started the VV-110/Varget duplex load for the 40 which I use now(12/63 2880'/sec). Concerning "getting the same " results from a single powder vs duplex, you might notice that relatively few duplex shooters have gone back to single powders; and it isn't because we just enjoy having 2 powders and doing twice as much measuring. I do agree that H-4198 is a really great single powder load in the 45 and have one set up with 62g H-4198/200SST.
