View Full Version : BR-5 usage/test loads

07-27-2016, 05:46 AM
Anyone currently using BR-5 ? It is supposed to mimic Unique data. I have been doing some testing & it seems to be off quite a bit. Kinda weaker so to speak ,IMHO. I have been playing around with various loads in .38 spl. . Anyone else testing ,or have loads worked up & if so for what gun? Just curious.- CASTER

Some test results for anyone lurking. I am pushing 150 LSWC with 5.5gr. Of Br-5. Still working on bumping it up. Fair accuracy the way they are.

Glad to see someone working with this powder. I suspect it'll be a good one.

As far as being "weaker" than Unique, you've discovered its a little slower than Unique. I think the surplus powder sellers err on the side safety and usually tell you to use data from a slightly faster powder and work up. A powder's speed will change a little depending on the cartridge, boolit, over-all length etc... So to keep people out of over-pressure results on their first try, they want you to have a plenty safe starting point, which is to data from a faster powder.

I find powders a little slower than Unique to be great in top speed loads for 38 Special, 32 SWL and get 45 Colts going as fast as I need. They also get about 80-90% of the top velocities in 357 magnum, but are very economical compared to case full loadings of H110, and are more fun to shoot. And that powder speed will really shine in the 380, 9, 40 and 45 ACP.

Ill bet you'll find your favorite 38 loads are toward the upper end.

Please post some results as you get them. Interested to hear how BR-5 works out for you.

I used 5 gr in my 1911 45ACP with a 230 gr TC boolit @ 845 fps, found it to be a tad more accurate than the same 5 gr Unique load. Will try it soon in my CZ52 and Tokarov 7.62x25

How is the actual burn of it? I HATE UNIQUE! It never seems to burn completely and get powder all over me while shooting it. Seems to clean up a little if you run a max charge but I do not like that at all.

It is a ball powder so it burns very good. Just got back from the range shot 50 230 rn with 5.0 gr shot good then shot 50 with 6.1 gr with 230 tc shotbgreat all INA big hole at 25 yds. It is cleamn also.

Went to the range with three loads of BR5 in my SCCY 9mm all with 125 gr Lee cast PC'ed and sized to .358 OACL 1.020
First load was a little hot but safe 5.5 gr BR5 accuracy fair
second load was better 5.0 gr BR5 accuracy all in a 3" sq. @ 18 yds
third load lots better 4.5 gr BR5 accuracy was in a 2" sq. at the same 18 yds
Ran 200 rds through it with flawless feed and eject.
Remember this isn't a range pistol it is a CCW 15 oz 10 rd double stack.

Was the 845 fps actual chronographed velocity?

I have been eying that powder at Bartletts and need something in that speed range.

It should do well in my 550 also

Yes it isn't the same volume so don't use the same measure you would with unique.

Been researching this powder and figure I can pull the trigger on it if someone wants to split an order in CA or Reno Nevada area.

357 Mag, us d Unique data roughly reduced 10%. 6.7gr with Magna 158 bevel base LSWC, CCI 550 (mag primer). Clocked 1050 +/-15 FPS from a 5 inch Smith & Wesson N frame. Not pressure signs. Accuracy not noted. Just throwing them over the chrono. To establish a base line

Just picked up two more jugs from gibrass.com on my way through Owensboro. Data on jug for 9mm and I’ve been using it with plated bullets to this point. 5.6gr under a Berry’s 124gr rn. I know...they’re not boolits but, it is what it is at this time....They shoot well and cycle all of my 80% firearms perfectly. From the B26 to the B34 and even the “Longslide”. They all are 100% flawless with this load.
I have been shooting 5.5gr under my 45ACP 200gr LRNHP Mihec boolit and it functions my B21 well. No hiccups at all either.
No chrono data at this point, but, maybe this summer....
Next on the agenda is 40S&W in the same firearm platform.
