Subject: better 2nd range session

hi all,

took out my Bren Ten Standard out to the range on Saturday (00JAN22). had a much better shooting session...but i still had a few hitches here and there.

i shot 30 rounds of remanufactured ammo and 30 rounds of REM UMC yellow box. at the beginning of the shooting session, i had three malfunctions where the slide would not fully go into battery. rounds 5, 15, and 23. i had one magazine malfunction...and i think i caused it with my thumb. no more magazine malfunctions occured and the modifications i made with my mags seem to work. i will still buy an original mag from Erv.

after going through the remanufatured ammo (with is pretty good), i noticed that the barrel hood wasn't sticky and didn't get stuck about 1/4" out of battery. looks like the gun is breaking in. once i got into the UMC ammo, i had NO malfunctions!!! accuracy with the UMC load is amazing!!! i was only doing function checks but still taking aim at the target and group size was only 1.5" at 15 yards! one ragged hole! only my S&W 610 and SIG P210 have this kind of accuracy.

i do have a gripe with the rear sight though. they get loose. the became loose again and i had to tighten up the sights again. looks like i'll have to loctite them when i'm happy with the functioning of my Bren Ten and i settle on a load for it.

i alternated both mags to see if one was more reliable than the other. both seem to work fine now.


Mike,

Okay...don't panic!!! :))
gotta tell u, i was on the verge of crying! hehehe...

the lube i am using has teflon in it and should help functioning. i don't have the lube with me, but it was given to me by a fellow shooter who uses custom 1911s that r tight. the area that gave me the trouble was the rear of the barrel hood...there is a little extention with a bevel on it that mates with slides breachface. i suspect that this area needed to be broken in. the slide rails seem to be broken in and still remain tight.

Magazines....always a problem with a gun like this where we are struck with using aftermarket replacements for the originals. If you are goig to fire your Bren, tweaking the mags to get them right iof they are aftermarket may be a necessary evil. i'm pretty sure these mags r original, but were made for the .45/10mm Dual Master conversions. anyhoo, the mags seem to work well now, but i will still get the numbered original mags from ESF.

Ammo...here's another variable that may have to be tested. While I recommended not using hot loads in the Bren to prevent any frame/slide catastrophies, you may have to go to a "warmenr" load to get proper function. Perhaps to the 165 grain loads. The original Norma loads were loaded REAL hot so the one load I would avoid like the plague is the Winchester 175 grain Silvertip load. It is loaded to the same specs as the Norma load and probably should only be shot in Glocks :) ammo used is high quality...even the remanufactured loads. the UMC load is a peppy load...not quite full load, but close. if i had NORMA loads, i wouldn't shoot them... would go into the collections. i'll be loading up some of my own loads to break the Bren Ten in a bit more. another 150 rounds i think it will be settled in.

Keep us posted on how you do. You are almost making me want to take my Bren out and fire it...almost ;) hehe...GO AND SHOOT IT! i'm bad, ain't i? hehehe

P.S. If Triton gets the Bren in production we may have an answer to the magazine fiasco. I hope! good news from the SHOT Show! Triton seems to be getting closer to coming out with a resurrected Bren Ten! seems Fernando wants to make this happen.

Hi Jon,

I have to say I am NOT surprised the Remington-UMC ammo improved performance. I had problems with ammo in my Glock 21 and was ready to take it to a gunsmith until I loaded in some UMC. It ate it like there was no tomorrow! Found out my Glock 21 does NOT like CCI ammo of any type including the brass case variety. It DOES like fairy warm ammo though. Think I will probably end up getting an original mag from Erv too. Not only does it increase the collector value but it gives better reliability too. Best of both worlds :)

P.S. O have a box of the original Norma hollow point 10mm loads. STRICTLY for collector purposes :)
