A while ago I picked up some Rio CSB-1. Does anyone have any 10mm load data for CSB-1?
Thanks!
The consensus based on my google-foo seems to be to use Universal data for this powder. Many folks report their jugs are marked as such. A cursory cross reference of their load data for 12 ga. seems to support that notion.
There is load data for 10mm on Hodgdon's site for Universal. But, the loads are on the light side. About what Underwood loads 40S&W velocity wise. So, hot 40, but pretty weak 10mm. Probably fine for a plinking powder.
This could help you so to work up a load from the 40S&W loadings...It is said to be the same a Universal (one of the Clays Shotgun powders there are 3 different ones) The Hodgdon Powders are Clays, International Clays and Universal Clays.
BE CAREFUL as this is fast burning powder and pressures can spike. Also there is a CSP-1P(density 510) CSB-1(density 520)

Thank you gentlemen.
I found some at my local gun shop today. It's been a few months and was wondering how the test loads went?
I have been working with CSB-1 for the past 6 months and I have worked up loads for the following calibers 9mm, 38 spl, 357 mag, 40 S&W, 10mm, 41 mag, 44mag and 45 colt. I have found that it developes pressure very quickly in regards to increasing the powder charge and has some large shot to shot variations in velocity. It is most useful in medium and target velocity loads.
The 10mm loads I worked up all used CCI LP and twice fired Starline cases with a strong taper crimp. All bullets were Precision Delta FMJ. 5" RIA 7' from the muzzle
180FMJ over 5.0 = 890 FPS
180FMJ over 5.5 = 972 FPS
180FMJ over 6.0 = 1044 FPS
165FMJ over 6.0 = 1013 FPS
Loads 2&3 were the most uniform loads but for some reason did not shoot as well as #4 in my pistol.
One thing I have noticed is that the wide variations occur prior to achieving what is probably the most uniform loads and at lowere velocities. But what is puzzling is that most of these loads are very accurate through my various revolvers and pistols. Some were as high as 75 FPS difference.
I would not try to develope magnum loads with this powder. I only use it for target loads. Don't believe that you can use Universal or any other available canister powder for your loading data. I loaded up the same grain loads that I used in CSB-1 with Universal powder and the velocities were no where near close. I would bet the presures are quite different too.
I contacted Maxim last summer after I recieved this powder and was told it was not supposed to be released in the US. They also told me that after they had completed their testing they were going to release it in the US in 2015 in canister form.
Proceed with caution it is not a magnum powder.
Thanks for the report elmo123, I have seen where others using this powder as well.
Could you post a picture of the CSB-1 powder here for us? About 8.0 or 10.0 grains in a scale pan, zoomed in at the closest focusing distance. It would be appreciated! :D
I don't have a digital camera but it is a grey flake powder and it meters good.
Don't have 10mm data yet. I'm loading 45acp - 6gr - 200gr swc coated falcon, should be 960fps.
Will chrono it when I can. Very accurate.

Elmo123, I understand many people have phones today that take great pictures. I use a EOS digital camera for the pull downs on the forum here documenting what is found inside the commercial ammo. I posted the picture above, that was on the RIO website showing several of their powders. I wish all powder makers showed samples like that, I like the powders that have identifiers in them like Blue Dot and others.
I am a dinosaur when it comes to technology my cell phone is a flip up and the pictures are terrible. The powder looks just like the photos you posted.
