6Bra versus 6mm Dasher

[Stan Taylor]

You missed the point. The BR improved came with the great bullets. I believe that is a part of their success. Today's Dasher and BRI are on equal footing. With todays great bullets they will both shoot better.

Thanks for a very valid assessment.
P.S. it's nice to get everyone off the couch for an educational discussion.

Boy, I wouldn't tell him that. Matt

Matt, that is once, I had flukes also but they will not repeat..... jim

The Dasher has a higher velocity node that most fail to mention. It shoots extremely well at 3050+ FPS. The BRI is not capable of this velocity.

Yes sir, My 2010 dasher that still hold both 6 and 10 group aggs for williamsport (10 shot) were running Spencer's at 3055-65. And I believe Leo's 2011 dasher score aggs the same, upper node with Spencer's. That said, I've beaten my own personal bests 3 times now in heavy class, but with a BRA running vapor trails. And all three of those seasons I never shot a rifle that wasn't a legal light gun lol.

Stan, if they had made brass for the Dasher I would have never changed.... jim

Stan, if they had mad brass for the Dasher I would have never changed.... jim

I think that's important. And Stan, if you've been working with a dasher, stick with the dasher. Truly learn the case. You'll be farther ahead to learn the case than to switch. I think the br-improved and dashers are basically the same accuracy wise once cases are made. I just like the better barrel life I seem to experience with my br-improved

You actually reinforced my point. What Dashers did in the past is in the past. There are still plenty on the lines today. What matters to me is head to head performance and we currently have that using the same bullets in each. In the right hands both are great cartridges and both can win. It’s simply hard to deny the recent success of the 6BRA. I understand why people like to stay with a cartridge they are familiar with and have had success with. Just a personal preference thing I guess.

I thought the record was 1.066 by a dasher 5 shots but I seen it on the internet so it must not be true...

Mike Wilson’s record was shot with 6BR Ackley (6BR-AI, 6BRA). I was on the same relay that day. Mike had actually bought the reamer from me a few months earlier. I got schooled again by Mr Wilson that day as did a lot of us. Samuel Hall

His record was shot with HIS (not Alex's) version of the BRA and it is somewhat different. I know because I have one those barrels, brass and dies.
I am not discounting the 6BRA and its accomplishments because they are many for its relative short time in the game. I do have a couple of barrels, one Wheeler version and one Wilson version. Maybe I'll shoot a record one day too.

Tom, you’re contributions the the 1000yd benchrest community are exceptional. The ability to roll multiple guns in two classes competitively is to me amazing. When re-emerging to the sport in 2016 all of my retired equipment was geared towards heavy. The financial burden to completely change was not an option. I struggled with the Dasher my first year experimenting with many bullets. I then discovered Vapor Trail and everything changed.

 

[Stan Taylor]

Whether you decide on BRA or Dasher, 6BR 300wsm or any choice of cartridges it's all about barrels, an bullets to be competitive on game day.

Mike may correct me, but I think I am correct. The reamer the record was shot with was my 1st BR-AI reamer. I sold it to Mike. Mike, jokingly named it the 6BRAW. “W” for Wilson. I still have a barrel made with the original reamer I use for 600 yards. I tweeked another reamer like it with shorter freebore. My old BRAI reamer was .463 at the shoulder which needed custom dies. Either James O’Hare or Alex made a version where you could use shortened Dasher dies. Which was a great idea, simplifying things. It had a shoulder of .460. I was trying to sqeeze out more case capacity out of mine when I first made it, but in the end I have found it does not make a hill of beans difference. I have both versions now. Now its down to “barrels and bullets”!

He consistently shot well. I believe he would of won both aggs except for a bad relay. I saw all his targets and the clusters were incredible. I believe at least two times he had 9 shots under the record. Matt

I have had 3 different dasher barrels and now have two Bra Light guns, both have Borden BRM drop-port's and Hammerhead stocks. Built the Bra's because I had it in my mind that the Bra's may shoot better because the case formation requires a lot less working of the Brass in the Bra. After owning both my experience has been either case can win and saying one is better than the other is a Ford vs Chevy thing. I have shot well will both and well you know with both. My dasher shot extremely well at 3030 fps. and I feel it had a slight edge over my Bra which shoots well around 2960. Also, my experience only I seemed to get that dreaded flier with the Dasher more often than the Bra and when you have real good conditions, at least for me I am able to shoot slightly smaller with the Bra. Saying all of this, probably not this year but god willing, next year, I will remove the oldest bra barrel and replace it with a Dasher, then shoot one weekend with the Bra and one with the Dasher for a season, then re-evaluate. Oh and if conditions are real ugly, well lets just say it wouldn't be the first time Matt Kline, Jay Berger and the rest of the 300WSM gang spanked us 6MM guys.

Ya, good old American muscle ..... lol.... but you don't have to worry about a detached retina..... jim

I can make you some brass if you want to change back. Not a problem for me !!

Sam, that cut down Dasher reamer was a winner for every one the use it. Barrel quality is the difference ..... and bullets..... I will take a hummer in a Br Imp. over the faster Dasher in a heart beat..... jim

 

[Hoodoo]

I've said this before and I'll say it again. Some/most (not all) are missing the point to all of these posts. 6br-ai vs dasher posts drive me nuts.

If people would worry less about what they got beat with, and worry a little more about why they got beat, they're personal scores would go up way more than switching to a different cartridge would do.

Look at how much time guys like Bart, Mousel, Mike Wilson, Lonnie, Shawn, Sam Hall, etc put into tuning every week, shooting in different conditions, different bullets, primers, brass, powder etc. They know what shoots well/best because you can guarantee they have personally tried it. Not read it on the internet, but actually tried it for themselves.

You want to know what makes a BR-AI better than a Dasher? Do some personal leg work and decide for yourself.

What if those Dashers have so called hummer barrels also. I know that more record Dashers have come out of a gun shop in Duncan, Pa than just about any other in the country. They have won Aggs at Williamsport, IBS events and numerous other competitions in the country. At one point in time they were winning quite frequently. The BR improved has been around for over 30 years, so has the Dasher. The BRA is nothing new. I made the mistake of slowing down my loads this past season because under ideal conditions it shot well there ( 2900). It would shoot 3” groups shooting slow and steady. At the higher node of (3050+) shooting faster it would print 4.5~ frequently. I didn’t realize this until there were only 2 matches left. I did not have enough time to fix my mistakes. My guns, for what ever reason shoot consist under adverse conditions in the higher velocity node.

Are you slam dunking me for bringing this question to the floor.LOL

I think there are more records shot from more places all over the country than from Mark Kings but maybe at WP. I'm shooting a 2998 with a BR Imp. and it doesn't do bad... Here again it is barrel quality. I ran Dashers from 2920 to over 3100 and all the do is shoot bad up there but drop back to 3060 and the come together better and around 3000 the shoot great, that was those barrels, now none are the same speed size, I have two Lederers that are 30 feet apart in velocity. I could chamber the slow one in Dasher and the Impoved would look to be faster.
I set five records with a Dasher and I like them a lot but to make great cases is a real pain, so at my age I need easy and the Impoved is that. It takes years to learn the Dasher or the Improved You go through 10 or 20 barrel you will ... One more tid bit I could never get the Dasher to shoot with H4350, it always had vertical and now I can get the Br Imp to do it.... go figure .... jim
