I’m tired of you guys and your BRA

[Chuckhunter]

Glad to see this old thread rejuvenated. It's been several years since the BRA splashed onto the scene so now might be a good time to ask. For those that have built and shot both cases, I would like an honest opinion as to which case in your opinions would agg. better at the end of an entire season. Not recommending any arguments, just curious, trying to get a handle on the general opinion. I have built and shot both and there are things I like and dislike about each. Once I get a general consensus, I'll give you my take, just in case you care at all.

Chuck, The Dasher has too much capacity for the nodes it shoots in, and too small to reach the next node. The Br Imp.is perfect fill for powder the same nodes as the Dasher shoots best in. The 6Br shoots good but it is hard to keep up with the conditions with it's lower velosity..... jim

Looks like I'll put 1 checkmark next to the Bra to start.

@johara1, So, what speed range are you saying the higher Dasher node is at? Is shooting the higher node in a Dasher a problem with capacity or brass withstanding the pressure?

I thought it was pretty small for three separate charges, I had to dig out my notes View attachment 1205856

There does not seem to be a correlation between the powder charges and the speeds ?

BL has the lowest charge but is listed with the fastest speed?
GR is the middle charge but is listed with the slowest speed?
Red is the highest charge but is listed with the middle speed?

The Dasher shoots ok at about 3030 but better at 3000 and below down to the 2920 node. The Br Imp shoot good at 3000 and down to the 2920 node. Now some will argue that you can run a Dasher at 3100 and I did but it will not shoot up there unless you think .2 and .3 is good.... If it doesn't repeat in the .1 or less 4 times in a row with low ES. it will never see a 1000 yds. If it does it will shoot in 4" or less for 10 shots, depending on the conditions..... jim

When I was shooting a Dasher my sweet spot was at 3030, I could go much higher but had the same result as Jim. The Bra I'm currently shooting shoots it's best at 3024 Avg. velocity which appears to be higher than most guys are shooting this case but it may just be my barrel. Once I get below 3000 the vertical starts to show up.

Thanks for pointing that out Jeff’


I’m not sure what to tell ya on that one ol buddy, I just read them off the review string function. (That’s the head scratching part)
Maybe I should read the instructions or just leave the chrono at home

SPJ I had similar results when doing a ladder with 103 VT's and H-4895
30.3- A.V.2946
30.4- A.V. 2936
33.5- A.V. 2947
Perhaps it's not uncommon when you're close or in a node.

Chuck, My best barrel the velocity is 2998 with a Barts 105, so we are close but the barrel maybe the difference ...... jim

Been trying to decide on a second 6mm barrel to spin up. Stuck between bra, dasher and gt. Have a creed now and is the reason I’m more so leaning towards the bra
