I tried the 6x47 and tossed it as well!
Been a few months now anyway I guess, and a couple years since it won everything. For what it’s worth, I ran the same same powder charge all year long, in 5 different Dasher barrels and 2 separate rifles with the only difference being seating depth/chasing the lands in 2016. There’s nothing wrong with a Dasher but if y’all wanna give up on it, that’s fine with me. Lol
Dasher and brx sound a lot cooler than bra so there’s that.
That was when everyone was handicapped with a dasher! No telling how scary you'd be with a BRX OR BRA!

Surprisingly, my 6.5x47 is one of my most accurate rifles!!!!!! And was very easy to dial in!
my 6BRX has been an awesome barrel and will defiantly be getting another very soon .. i had to up the load at approx 1100 or 1200 rounds as it lost 70fps (from 32.4gr to 32.9gr) but once i did that it was back in its sweet spot and shot 2 Aussie fly national records at 1500 rounds on barrel
i have had a go at 2 6BRA barrels, 1st barrel was a dud but the 2nd one has also been hard to tune (best so far has been 103 copperheads and benchmark 8208/ IMR8208 XBR but i pulled off barrel to get my re chambered 6BRX working)
about to put 6BRA back on and try 107gr serria MK as i just scored some more and they showed great potential when running barrel in (i couldn't get anymore at the time)
I've had 2 mates who struggled with the dasher, it was hard to tune (both of theirs had a small window) and when it was in tune they shot great but both went away from a dasher
i'm about to order a new 6BRX barrel, just hope its as good as my 1st barrel

A few years back I bought a Bat SB from Voldoc that he had made a kill on a prarie dog at 1412 yards with. It came with 2 BRX barrels. I was a confirmed Dasher fan. I thought I would try the BRX barrels and if I did not like the BRX I would have them punched out to Dasher. Guess what. I loved the BRX and shot it exclusively for a while. I have hit more 800 yard eggs with it than any rifle I have. I use the same load in the BRX as my Dasher. Never had a new, fresh BRX barrel but I think that may be my next project.
I also want to try a BRA.

This hard to tune stuff cracks me up. Nothing on a BR case head is "hard to tune". Sometimes you get a good barrel that likes the first thing you give it, thats not easy to tune, thats giving the barrel what it wants. Give the best barrel a powder/bullet it doesnt like and its hard to tune. I can send 10 barrels to one guy and all 10 will win matches without a mention of hard to tune another guy may get a bad barrel every time. Its knowing how to tune and figuring out what to do next by looking at the target. When I first got into competition all I did was tune, I burnt out barrels learning. I wish there was a good tuning reference I could point guys to but there is very little quality info. I would bet if a guy took 3 or 4 bullets and 3-4 powders as well as some different primers to the range and shot 3 shot groups with different combos he would not have many hard to tune barrels anymore. Every new dasher barrel I got would get that treatment and after that first day at the range I knew what powder/bullet/primer to start tuning with. The barrel I shot more 1s at 1k with ended up liking Varget, the only barrel I have ever owned that prefered Varget, if I forced H4895 or rl15 down it like usual it would have been one of those hard to tune or bad barrels.
If you get your 284/Shehane tuned right it will hang with any 6mm at mid-range Fclass. If the wind really gets up the 6mm's go bye bye....just for the record I have shot a 6br,6Dasher,6SLR and a 6BRA (still shoot this one on "good days") for mid-range Fclass.
I don't shoot F-class so I'm gonna trust you. In 600 benchrest 284/Shehane, as good as they do shoot, can be competitive but you're not gonna win with it. I have an absolute hammer HG barrel (60# total gun) that shoots almost as small as my dashers in testing. With sight in periods and 5 shot groups, the 284 will blow around just as much as the 6's at the end of the day. I know it doesn't sound right but I proved it to myself anyway. I could manage 2nds and 3rds with it but that was about it. Put a dasher barrel back on and won a lot.
Apples (Benchrest) to Oranges (F class), in my opinion.
That's why I qualified my statement...
Sorry, didn’t mean to sound negative, you did clarify, just think the games are different enough that ultimate agg grouping(precision) is less important in Fclass (accuracy) and ultimately important in Benchrest.
I have seen a lot of 600s at MR in Fclass with 284(and derivatives), so believe it is and can be competitive there.
Thanks for the dialogue.
BRX and don't look back, easy to tune, seems most are doing good at 32 gr to 32.5 gr of varget, I have won at least 8 300 yard varmint for score matches maybe 2nd once heres 300 yard sight in my scope for match 6 shots, best part I'm 71 and have cataracts both eyes, just think if some good shooting young guy could do, beat a bunch of young guys

Jeff,
I went with the 6BRX because my gunsmith was building Bob Crone's guns and had his reamer. I have done very well with the BRX. I shot 3 IBS 600yd benchrest with the BRX. I have resisted changing. All of my 6BRX's shoot best at 2975 f/s. That is where the 6BRA is running, you don't need more speed.
I would go with the one, that I could get a F/L die with out having one made. You can get a Dasher and BRX, I don't know about the BRA.
If I were to change, I would try the BRA, because the fire forming would be easier.

Look at the results from 2018 IBS 1000 yard Nationals. In my opinion, the Dasher kicked the BRA's ass even though there were more BRA's. If you couldn't get a Dasher to shoot, something was wrong, maybe reamer. I have my flame suit on. Matt
Hello to everyone,Let me start by saying thank you for all the great info you share with newbies like me. I'am new to competition shooting and building my first benchrest rifle currently with Dave Bruno. I have chosen the 6BRA .268 neck exclusively for 600 IBS at the bridgeville De range ( i live 30 miles from there in Maryland) Roy Hunter LR stock, nightforce competition 15-55x52, Bat MB action , Bix n andy trigger, Krieger 28" 7.5 twist .237 barrel with Ezell tuner. I understand most shoot H4895 around 30 to 31 grains. I fully intend on testing with that powder starting low of course but would like to test other powders as well for the exact reason you stated Mr. Wheeler to avoid forcing a powder on a barrel. I don't want to just take what I read as exactly what I will use, I want the barrel to tell me what it wants. I just don't know where to start with other powders. Any suggestions would help greatly. Thanks again, J.D. Baker
Big difference between a 6.5x47 and a 6x47. The 6.5 wants to shoot and seems to be easy to tune. I think the capacity is too much for a good 6. Seen lots of them at 1000 yards and none were very competitive. On the other hand, the 6.5 version set some records and is winning. Matt
