How about a 6BRA vs 6 Dasher shootout?

[SHall]

I started experimenting with the 6BRAI (6BRA as Alex Wheeler and others call it) in 2015. I intended to run it exclusively in 2016 at 600 yards. I found out I had stage 3 colon cancer in early 2016. I am cancer free now, THANK GOD! But it put a damper on my shoooting for sure! Several other great gunsmiths and shooters have picked up where I left off. Gunsmith, Alex Wheeler has done ALOT with the round. To me I think the round surely proved it is here to stay last year! It has 2 pending IBS 600 HG Records by Bart Sauter. An amazing 0.282 inch five shot group AND a perfect 50 score. Mike Wilson shot 2 pending IBS 1000 yard LG records last year with it! Another amazing 1.068 inch group AND a perfect 50 score! This means it will have the SMALLEST 5 SHOT GROUPS EVER SHOT IN ANY 600 AND 1000 YARD COMPETITIONS!!! Tom Mousel and Mike Wilson probably test and tune more at 1000 yards more than anyone else on the planet. They are both sold on and using the Ackley Improved now! I am not sure what they are, but Tom has some pending 6 or 10 target agg. records set in IBS 1000 yard competition in 2018. Last I heard Mike Wilson was nipping on the heals of an IBS 1000 Yard Score Agg. record with it this past season. That means the round can agg. over a full year of Long Range competition also! As we talked about earlier, the 6BRAI is definitely easier to form vs the Dasher. And over a years time, it has (pending) broken some very long standing Long Range records! Is it more accurate than the Dasher? You be the judge. But as for me: I now have 2 6BRAI reamers. I sold my record setting Dasher reamer. Rechambered all my good Dasher barrels to the AI. And only have the 6BRAI chambered in new barrels now!
Again, please no smart a- - or snide comments. Thank you, Samuel Hall

It takes both, don't let anyone kid ya.... jim

Maybe it’s just me; but I’ve had good shooters beat me using their equipment, switch equipment with me and still beat me. I’m willing to give credit to you archers.

When I started experimenting with 40 degree shoulder 6BR back in 2015 it was not to find something more accurate than the Dasher, it was to find something that was EASIER THAN THE DASHER. I had turned, prepped, and blown out hundreds of Dasher brass years ago. It was all at the end of its life now. I had always noticed with a max load in the Dasher it still did not fill the case, there was always more space in the case. PPC shooters wanted a full case! So why were we blowing the case out and strething it so much? I had heard the 40 degree shoulder makes for a “perfect boiler room” to burn the powder more effieciently and completely. I think of it like a car engine’s combusion chamber. Think of a street car vs a NASCAR piston chamber, change the piston’s head angles qnd you get a more effiecient combustion chamber and more HP out of the same displacement. I don’t know all the correct engine terms here, but I hope you get the point. In 2015, I had shot BR long range many years and I did not want to spend so much time making Dasher brass again, so I took a 6BRDX finish reamer I had and ran it in a standard 6BR barrel I had to just enough to make a 40 degree shoulder to experiment with. I quickly found the brass was easy to make and kept the long standard BR neck. Maybe it was a fast barrel, but I chrongraphed Berger 105 Hybrids up to 3050fps with only very mild pressure signs, not enough to ruin the brass after many firings. But I found accuracy was between 2920-2970fps, faster than that and groups definitely started opening up. The barrel as a BR would start showing pressure after 2900fps. I then rechambered another std 6BR barrel the same way to confirm my findings. It had been a good shooting 6BR barrel. This barrel started off shooting better with the 40 degree shoulder than it had with standard BR chambering. I found it easier to tune than any st BR or Dasher I had ever had. The first time out I shot two or three groups in row in the 0.8 inch range at 500 yards WITH different powder charges! I had never had a Dasher or standard BR shoot that good. This was enough info. for me to now to have a reamer made.
I found the 6BRAI (I call it) easier to tune and much easier to make good cases. It kept the long BR neck. Fire forming rounds were very accurate and brass could be fully expanded after one firing. With Dasher brass I like to FF twice at a low powder charge or I would lose primer pockets early. The AI reamer I had made was a .272 no turn and was made to have a “crush fit” of 4 thou. (0.004) for std. 6BR cases just like P.O. Ackley use to recommend. The FF round head spaces on the neck shoulder junction, so no need for false shoulders or necking way down to get a lot of tension so you can set the round in the rifling hard tO FF the Dasher.
With all this said. Do I think the 6BRAI is more accurate than the DASHER? Probably not. Like said before, accuacy has more to do with a great barrel matched with great bullets, ALSO, a great shooter shooting in good conditions. The question to me is: WHICH ONE IS EASIER TO MAKE AND TUNE? To me that easily goes to the 6BRAI. Unless you are very experienced with the Dasher, you will be able to make very good 6BRAI fire formed rounds much faster and easier than you vrs the DASHER, this should lead to better accuracy for the less experienced shooters.
Note: I have just about quit posting on here for people picking my posts apart. I don’t pick other peoples posts apart! I don’t claim to know it all, I am still learning, this is all my opinion based on my findings, please be respectful!

Very interesting learning how it started. Thanks for sharing.

On another post, where a gentleman asked for help in deciding which cartridge to go with a Dasher, BRA or BRX. I made the controversial statement, “Anything but a Dasher!”. It wasn’t my intention to upset the Dasher Shooters or to turn things into a BRA vs Dasher thing. In hindsight I should have said something along the lines of “In my opinion I would personally go with BRA, BRX and Dasher in that order.” That would have minimized the polarization and divisiveness.

However Mr Hall’s findings are exactly what I have witnessed. The brass is much easier to make and it’s been very easy to tune. On the other hand MY experience with a Dasher was just the opposite. That can be possiblely credited to several things, perhaps my lack of experience with the cartridge, incorrect reamer, perhaps bullets (but I used More than just my bullets), powder choices....but for ME life got better when I sat the Dasher aside and started shooting the Grinch and then migrated to the BRA.

Baart, I see you mentioned the BRX. What is your experience with it.

Jeff,

Personally none. I was going to try the BRX but felt no need to after shooting the BRA and Grinch. I have several friends that shoot it very well. I only mentioned the BRX because it was one of the cartridges the gentleman was asking to us to pick from in a previous thread.

Bunch of us here in Colorado been shooting LR steel matches mag feeding our 6BR's and Dashers for a few years.

We shoot this match together. http://sportingriflematch.com/

We've had the 6BR's VS Dashers "shootout" at the SRM match. I and couple of my buddies chambered 6BRA's. So this year we'll have some Dasher vs 6BRA fun!

But just as I don't remember who out shot who 6BR vs Dasher, won't remember very long the Dasher vs 6BRA outcome. I will though remember the time spent with my shooting buddies!
