Guys
Sorry guys, I thought this post was about CFE powder, My info posted below is for CFE powder only. FWIW, As used in reloading cartridges from caloric bomb tests, this is the burn rate of the CFE powder, Burning rate factor, The burning rate coefficient during combustion of powder. Fast IMR 4227----------------1.0140 Hodgdon H4227---------0.9700 Hodgdon Lil-Gun--------0.8550 VIHTAVUORI N120------0.8441 Accurate 1680-----------0.8050 Hodgdon CFE 223-------0.5330 Powder Heat of explosion, The energy content per unit mass of specified powder. Hot Accurate 1680-----------4180 Hodgdon H4227---------4040 IMR 4227----------------4040 Hodgdon Lil-Gun---------4090 IMR 4007 SSC-----------3936 Hodgdon CFE 223--------3920 IMR 8202 XBR------------3920 Ratio of specific heat, The ratio of consent pressure of specific heat, to constant volume of specific heat. Hot Hodgdon H4227------1.2320 Hodgdon Lil-Gun-----1.2320 Accurate 1680--------1.2340 Hodgdon CFE 223----1.2384 IMR 4227-------------1.2380 I have only shown the powder on each side of CFE powder, or powders that were mentioned, I have all the current US powders in the XL spread sheet, with the above info. HTH, Don

Don, we're talking about the new CFE BLK, not CFE 223, lest anyone confuse the two. C A R E F U L !!!

Looking over the data you had posted, Don, I became even more aware that there's still a lot of information concerning reloading that I know nothing about, and probably never will understand. I'm thankful for a lot of loading manuals and a sense of "keeping it safe," and am not at all sure if I could really use all the available data if I had it before me. More proof that a putz is a putz.
I think it might be a good idea to edit that previous post in some way or another. Jus' sayin' |

Hey Don, if that's the worst screw up you ever make, you're still doing really well and ahead of most.

Anybody know how close it is to 2200?

The chart I just looked at showed it listed as #69 and 1680 one step faster at #68. I couldn't find 2200 on the chart.

Cfe blk
Can not locate the info now, but read where it is right around H332 and Rl 10 in burn rate. Bill K

What is? 2200 or CFE BLK? I know where 2200 is in my stuff, I'd figure someone had some direct comparison by now. 2200 is a hell of a lot quicker than RL10 or H322 in the 6mm 223 case stuff I've tested it in.

Accurate Powder lists their 2200 the same burn rate as RL7 and Hodgdon lists RL7 #71 on their burn rate chart and CFE BLK #69 so it would appear 2200 is very similar to CFE BLK but a smidge slower.
