This is an updated smokeless powder burn rate chart. Top left is fast burning-bottom right is slow burning. I've never loaded 7wsm but most other wsm's prefer something in the burn rate from the 4350's to retumbo.

CFE223 was designed as a fast burning powder for 223/5.56 sized cartridges. It's a great powder, though pretty temp sensitive, for cartridges of that size with few exceptions. Usually for bottlenecked cases the bigger the case the slower the powder used, but other factors such as case design and bore size affect that (hence RL7 is a great powder in 45/70, even though it is a fast burning powder in a big, straight walled cartridge; IMR7828 works really well in 243Win and H4831 works great in 25-06 because they are overbored).

The 4350 range of powders (IMR4350, H4350, A4350, RL17, Staball 6.5, etc) are a medium-slow burn rate, and work great across most big game cartridges. The burn rate table will show you many more powders in this range, but realize that this chart is not to show equivalent substitutes, as a) burn charts from different sources differ slightly, and b) you must use load data for the SPECIFIC powder that you are using; ie don't try to infer load data from the chart, just use it to help in selecting a powder for your cartridge.

As has been mentioned, use published load data from reputable sources. Hodgdon, Barnes, Nosler, and Alliant have good online databases, and good printed manuals from Lyman, Hornady, and others are available as well.

Very good advice given above. Cannot stress enough following published load data.

You should be able to find load data at powder manufacturers sites. I know Hodgdon has data available for their powders.

I haven't been in here much over Christmas, but thanks to all the responses. These have all been extremely helpful

64grs of h4831 with 162's in mine

A good read on the 7wsm
