1SOW Posted August 7, 2014 Share Posted August 7, 2014 (edited) Has anyone had experience loading CSB5 (shotgun powder made in Spain) out of straight wall pistol loads. Load data looks promising. Edited August 7, 2014 by 1SOW Link to comment Share on other sites More sharing options...
Smitty79 Posted August 8, 2014 Share Posted August 8, 2014 I have 8# on order. I will be loading 9mm and 45. I will post data when I get it. Link to comment Share on other sites More sharing options...

Smitty79 Posted August 8, 2014 Share Posted August 8, 2014 I wish I knew what gun, OAL and bullet this data came out of. I am guessing that this is FMJ shot through a 5 in 1911 with a 1.20 OAL. What do you think of this as a starting load and a work up: SNS 230gn Round Nose with no lube groove, Loaded to 1.225 OAL (could go longer with this bullet gun combo), Winchester LPP, R-P pick up brass. I will be shooting out of a SAR K2 45 (4.7 in barrel). I will start at 4.2gns and work up in .2gn increments to indications of bad pressure or 5.2gns. I only need 761 fps for 175 PF. If I get over 800 I will probably stop there too. Given the lack of history with this powder, I will probably take my laptop to the range and graph the velocity vs charge data.

1SOW Posted August 8, 2014 Author Share Posted August 8, 2014 (edited) That's a conservative starting load, so you should be fine. Going up .2 grs at a time is also what I'd do with the wide load range given. Sure would have been nice if it showed pressures, which means it MAY HAVE come out of an actual pistol instead of a test bbl with pressure readings...

acoop101 Posted September 25, 2014 Share Posted September 25, 2014 Where are you guys funding this powder? I'd be interested in giving it a try. Link to comment Share on other sites More sharing options...
1SOW Posted September 25, 2014 Author Share Posted September 25, 2014 (edited) http://americanreloading.com/en/32-smokeless-pistol-gunpowder And another site I haven't visited has been mentioned. The guy there, allowed me buy 4 lbs instead of the 8 lb minimum order shown on the site. Smitty has done some tests and I followed him. The powder granules are very small light colored discs, two laying flat will just fall into a 9mm flash hole. They are also extremely light weight so getting n320/7625 powder drop consistency didn't happen with my Lee Disk system. After that, 4.2, 4.3 grs fills the case to slightly below or just touching the base of a 124/125 HP/FP bullet seated a little deep and gets 133-ishPF. The above powder data is scanty and shows a wide load spread, but small changes made noticeable differences over my chrono. I saw no smoke, and it's moderately clean. Haven't tried heavier bullets I need to shoot it more before I'm sold on this powder. Don't get me wrong, it will run for 124/125 minor PF; but IMO it's not God's gift to 9mm reloaders. . P.S. I just revisited this site, and they have renamed and relabeled the powder jugs to "Commercial #5". A powder distributor friend had told me it's not legal for these guys to relable and sell the MaxaM powder not approved for import. I don't know anything about this aspect---just saying. He also told me it IS legal to buy it. Edited September 25, 2014 by 1SOW Link to comment Share on other sites More sharing options...
SethT Posted September 27, 2014 Share Posted September 27, 2014 Would love to try this stuff in .357 Mag cases, but I can't find load data for anything other than 9mm, 40 and 45. Link to comment Share on other sites More sharing options...
1SOW Posted September 27, 2014 Author Share Posted September 27, 2014 Well, there IS the old way to work up without load data. I'm not encouraging that; but if you do, I'd treat CSB-5 like a "hot Powder" in a very careful load work-up. I also would carefully use a chrono and look for "any" signs of overpressure in the cases. If the load increases show any abnormal or non-linear speed increases with small increases of powder---I'd call it a day. But that's just me.

Smitty79 Posted September 27, 2014 Share Posted September 27, 2014 When I did my first 9mm tests, I started so low the gun wouldn't cycle reliably. Link to comment Share on other sites More sharing options...
giova22 Posted October 20, 2014 Share Posted October 20, 2014 Hello I use csb5 for 9x21. Same oal than 9x19, pratically the same cartrige. 4.2 grs 123 cast RN bullet 29.3mm o.a.l. 1050fps fiocchi primers in Glock 17. Best regards Link to comment Share on other sites More sharing options...
jamesb74 Posted October 20, 2014 Share Posted October 20, 2014 I have a lot of this. Have only loaded for .45 so far. But it has met and surpassed expectations. Hi Tech reloading was the last place I saw any. I don't know if they still have some though. I want to load this for 9mm as well. Link to comment Share on other sites More sharing options...
1SOW Posted October 20, 2014 Author Share Posted October 20, 2014 I've shot a few hundred more rounds loading 4.25 avg. grs under 124 MG/Zero/PD JHPs and they've all shot and feel well. If VV n320 doesn't become available soon, I'll be buying more of the MaXam CSB-5 as an available alternative. Link to comment Share on other sites More sharing options...
IDescribe Posted October 20, 2014 Share Posted October 20, 2014 How is accuracy? Link to comment Share on other sites More sharing options...
Steve RA Posted October 20, 2014 Share Posted October 20, 2014 Seems from the info above to be slower than Clays. Wonder if #7 or #8 is available in U.S. anywhere ??? (Larger the # - 1 to 10 - the faster the powder) Link to comment Share on other sites More sharing options...
1SOW Posted October 21, 2014 Author Share Posted October 21, 2014 Steve, The "MaXam" "CSB" powders range from #10 = slowest (a guy in Spain says it's close to the same burn rate/speed as Unique), # 8, #6, and #5 that is the fastest of these--closest to vv n320., The MaXam chart shows some more below these that is said to also be slower. These are all designed as shotgun powders. There is another Spanish shotgun powder--can't remember the name offhand-- that tends to be slower yet. It's available here at one or maybe more sites. RIO shotgun shells use these powders. Link to comment Share on other sites More sharing options...
Steve RA Posted October 21, 2014 Share Posted October 21, 2014 Looking at the chart - pages 10 and 11 - it appears, looking at the loads, that the higher numbers require less powder for the same pressures. This makes me think they may be faster. https://www.maxam.net/media/Default%20Files/Outdoors/MAXAMComponents.pdf Link to comment Share on other sites More sharing options...
1SOW Posted October 21, 2014 Author Share Posted October 21, 2014 (edited) It's drawn screwy to me. Look at the "ARROW" pointing up. The bottom of the arrow says FAST. As you go up the arrow, the powders get slower. I corresponded with a reloader in Spain. He confirmed this. The powders that are made by the main company are about all they can get in Spain. He shoots a CZ Shadow 9mm for IPSC using a slower powder.he says is comparable to Unique. Edited October 21, 2014 by 1SOW Link to comment Share on other sites More sharing options...
