Maxam CSB 1M Powder (Thoughts? Experiences?)

[tal3nt]

I just picked up a 1lb bottle the other day. I plan to use it on some 9x19 using Xtreme 115g HP bullets. Going to start with about 4.8gr beneath the bullet.

Has anyone else tried this stuff? Is it any good? Should my specs be okay? BTW, I've only been doing this for a short while now; still much to learn. Any tips would also be appreciated.

I've been told that data for Universal powder works good for CSB-1. My Glock 23 likes 3.9 gr. of CSB-1, Winchester brass, Federal small pistol primers, and pan-lubed Lyman 401638 (175 gr. lead - shot as cast, .403 dia.) bullets shot out of a 4" Lone Wolf barrel. This recipe yields 790 fps and leading is minimal.

I actually use CSB-1, as I got into reloading when there were almost no other pistol powders available (for a decent price). The data for universal is a good starting point when I do my loads. I find that CSB1 works well for 380, 9mm, 40, 45, and 38 special. It's a fast burning powder and relatively clean.

I would probably advise starting at the suggested lower end (4.5 gr for a hollow point) and work my way up. Actually, if you're using Xtreme's copper plated, you may want to consider that you should probably treat copper plated as a lead cast bullet, so you may even want to start even a little lower (the suggested is 4.0 for LRN)

I use Xtreme 115 RN and my pet load is 4.4 gr of CSB1

I took a chance and picked up 5lbs back in January after getting tired of checking online and in store (this was before I realized that the Hogue Pro Shop is only 30 minutes away) and I haven't had anything to complain about thus far. My only other experience with pistol powder was W-231. I've gone through around 2,500 or so rounds.

It meters pretty consistently through a Lee Pro Autodisk. I used to spot check every 20, but now I'm confident in the drop. I never found that a double charge could "sneak through" as ~9 grains of the powder is way more than can actually fit in a 9mm case. My digital scale is saying around 4.5 grains under a 115 grain RMR plated round nose. I don't have a chronograph so I'm not sure what the velocity is.

I don't find it to be very smokey/dirty. I actually noticed that my load was much less smokey when I had to borrow someone else's ammo during a Steel Shoot (not sure what his load is). I've been using the same load in my M&P 4.25" for IDPA, USPSA, Steel Challenge, and a Pro-Am Style shoot. No issues that I can think of that would stop me from using it or purchasing again.

I also noticed that it leaves residue when you're close to the target. Not sure if that makes a difference, but it looks neat.

All excellent info; thanks fellas

What's y'all's OAL on the cartridge for a 115gr jacketed RN??? (Xtreme bullets)

[pdoggeth]

I use the Hodgdon suggested OAL 1.1" . This is for regular round nose though. For the hollow point they suggest 1.125".

[David-K]

I'm typically at 1.15" when using a round nose. But also remember, your gun will often determine what the propper COAL should be. Example: I have a Ruger SR9 that couldn't hit the side of a barn when using 147gr Xtreme's with a COAL of 1.12. But, through my Hi Power, no problem. At 1.15, the Ruger starts to behave.

[tal3nt]

It's crazy how much a hundredths of inch can affect the cartridge. I'm running Glocks though, so my understanding is COAL isn't as picky out of Glocks? I'll crank out 50 @ 1.15 and see what happens. I'll also start with 4.4gr of powder.
