What we are interested in is that all important "agging capability".
The truth is, there are a multitude of powders available that are in the burn window of a 6PPC; 322, Reloader-7, 2015, 748, N130, Norma 201, Tubal, etc. But, we tend to find the best agging capability with a very limited number, N133, along with 322, being the most suitable in the USA.
When a powder manufacturer puts load recommendations, they cover the entire senario from the fastes to the slowest. For instance, you can find loads for a 30-06 from IMR4064 all the way to H4831. Some manuals even list 3031 as a suitable powder with lighter bullets. Heck, that stuff is as fast as most 4198.
You can actually achieve about the same performance, velocity wise, from most of the powders listed, (from fast to slowest), but usually just a few will give that accuracy everybody wants in combination with acceptable velocity.
I might try it in my 30BR, although on paper, it appears to be a tad slow. It would probably run out of room in the case before it ever hit 2800 with a 112,
but if they all hit the X, what the heck.
Quite a few HBR Shooters use 322 in some of the more popular HBR chamberings. This new powder might be perfect for something like a 30x47.,
This might be a great powder for cases such as the 308 with 140 grn and lighter bullets out of 22 inch and shorter barrels........jackie
. I have ordered 2# of 8208 XBR but it might be a month or so before the order is recieved . So I'm trying to get some heads-up before hand
