Commercial #1 ( csb-1 ) reviews and feedback

[Saxmann10]

I have some commercial #1 powder from American reloading
Says to use universal data looking to load 380, 9mm, 38spl , 357mag and 45acp I’ve had good luck with cast target loads for 9mm and 45acp does anyone have any feed back on 380,38spl and 357mag

When I loaded the CSB-1 I picked up, I felt that it was a bit faster than Universal and was closer to International. As with all of these non canister powders, it's best to always back down 10% and work up or down as pressure signs allow. I was able to develop a 40 cal 160 gr RNL load for a 1911/2011 pistol that went 4.9-5.7 gr. 4.9got me an average of 970 fps and the 5.7 load got me 1073 fps. These were 10 shot averages.

The only other bullet/gun combo I had with csb-1 was a 110 gr LSWC in a Glock 34 (Before anyone gets worried, I replaced the factory barrel with a Lone Wolf traditionally cut barrel). My powder charge was 4.3 up to 4.9 gr. 4.3 was 1190 fps and 4.9 was 1285 fps.

I still have at least one can of CSB-1 and a can of CSB-1M (which is supposed to be similar to Titegroup weight wise).
