Dasher shooter, talk me out of a BR

[Agreen_3822]

Been thru two barrels with a 20lb Dasher for a prs rig. Second barrel isn’t toast but my brass is wore out and cracking in front of the case head. Bought a new round(600) of br brass and I’m having a hard time justifying the money for hydroforming or using my inventory of primers/powder to form cases. I’ve made the decision to purchase a reamer this go around and the dies aren’t a concern.

There is a run your loads slow and consistent wave going across the prs mainly with a group of very good shooters who promote watching trace/impacts and light recoil. My current setup(dasher) I’m running 109 hybrids at 2930. That’s where my node was after switching from 105’s which was around 2955.
I also have a 6gt 109’s at 2950 and 6creed fast as you want them in the stable if I need the speed. So maybe I am just jumping on the band wagon or looking for something to run in the 28xx’s and try to watch trace better.
Anyone have any real world results with bullet trace when dropping 100fps into the low 2800’s? What about wind at 900-1200 yards? Also concerned about the loss of target moving energy that guys running 223’s always complain about.

Go with XC. Feed/ eject more reliably than the BR, just as easy to tune, no fireforming and a touch flatter then the Dasher.

My buddy Jon Pynch shoots both a dasher and 6br. Rifles weight about 25 pounds after all the weights are in them. I just built a prs gun with a 6 BRA. I know he runs the dasher in low 2900-2890.

Do a bra you could run similar speed as the dasher and do a match fireforming

I shot my original 6BR at 1000 yds. My load was 105 vld's @2780 with single digit es. I was at a serious disadvantage against my buddies with 6.5 creed and 6.5x47L. Wind calls were harder for me and slight changes showed on target more than it did for them. We had zero problem seeing vapor trails and splash with all three guns. Needless to say that barrel was rechambered to XC right after and I'd never go back to standard BR unless shooting close inside 600. Just no reason to start in a hole and make things harder on yourself. Can run the bolt much faster with XC too.

Thanks for the response, but I feel like the Xc is a tiny niche between the gt(tiny niche itself) and the 6cm that’s going the other way from the dasher.

XC gives a little room to chase the lands if you're into that. Creed almost does not give that opportunity. Really only difference

You can shoot a match fireforming the dasher. Itll be just like a 6br. Id go with a longer case thats magazine friendly and run it in that same node your bullet likes (29xx). Brass will last forever not pushing it, itll feed correctly, you can bump it up if you ever need to and brass is easy. 243, 6xc, 6cm, 6creedmoor are all a better choice for prs than a br based case.

I have no knowledge about magazine fed LR rifles. I’m a BR guy. Chamber a 1-8 twist Krueger in 6Dasher with a.155 FB. And I personally like a .166 NK. Shoot VT’s 103 seated .010 in and you should be in the ballpark. The velocity range of 3005 to 3060 is a good place to start. As always start low and work up using a chronograph.

go BRA

no hydroforming or jamming needed

and you’ll be able to get within 50fps of a dasher

You can buy new Dasher brass. No fireforming.

This: https://www.petersoncartridge.com/match-grade-brass/brass-rifle-casings/6mm-dasher/. Sell the other brass and don’t waste your components fireforming.

Everything above mentioned shoots, just do what works for you, i shoot a bra but would shoot a dasher or xc also. They all work and in all honesty they all shoot without having to push velocities.

i have had good luck with Alpha brass in 6 Dasher as well

NO!
DON'T DO IT!

There, i tried....

I will probably never shoot another dasher again for PMS. Why bother. 6BR does the job with no funny business. Caliber selection in PMS is almost pointless. You already have 3 guns that shoot 6mm at basically the same speed. It's really all about circus stages and positional disco. Build a 223 for practice instead.

 

[Agreen_3822]

Thanks for all of the replies. I guess I should have stated in my initial post that I’m not interested in anything faster than the dasher, that’s what the gt or creed are for. I was really just interested in first hand experience going from dasher(or equivalent speed cartridge) to br, and what happened down range say beyond 500 out to about 1200.

I don’t mean to sound negative here - but if you aren’t winning with either a 6 creed, 6gt, or 6 dasher available to you already... a 6bra or 6br isn’t going to change your results.

i’ve qualified/shot the PRS finale three years in a row with varying flavors of equipment and unfortunately have not sky rocketed to winning either, so don’t take my advice the wrong way.

if you want to build buy a new gun, by all means do it, it’s fun. if you’re serious about improving your match finishes, throw every gun away but one (dasher is just fine) and don’t waste a minute noodling around with the other calibers.

you can do 300 positional dry fires in an hour ( 10 shots - 2 minutes on the clock then 2 minutes off), less than it takes you to charge and seat live rounds for another caliber.

it sucks to hear someone say the gun isn’t the issue, but if you’re on this site and already own multiple 6’s that shoot well at distance then another gun isn’t going to change your results unless you are questioning the current guns and it affects you mentally.

speaking of which, i probably should go do some positional practice

I’m not looking for the magic cartridge that will propel me to the top. Unless you know what it is, In that case I’ll build two of’em.

The creed will be a gun to shoot factory ammo when I don’t have time to load, or a range where I need the speed. The gt is a ppr production gun I compete with in the regional series. The current dasher rifle is what I intend to shoot in open for the two day matches. May not be for everyone but it’s what I’m going to try. I was at the finale also, first time for a east coast guy to see wind like that.

This thread wasn’t started looking to find a caliber to make me better or some secret sauce, again just looking for personal experiences between the two cartridges. Trying to weigh the pros/cons of them head to head.

All things considered, that wasn’t even bad for the wind in OK

Here is some food for thought on the original topic. A dasher with 105’s going 3000fps is within .1 of a BRA shooting 109’s at 2850 all the way out to 1000 in 10mph full value. What bullet you use might actually matter more than the velocity. There is a reason so many prs guys are coughing up for a-tips.

My personal experience had been I can see all impacts (or misses)~ 400 yards and out with my 21lb 6creed. so there aren’t that many shots I think the creed is hurting me in, I also can’t always tell which way a plate is rocking beyond about 900 though with the 21lb BRA unless it’s way on the side for a big twist. For the bulk of most matches with 90-95% of the shots between 400-800yd I honestly don’t think the gun really matters as long as you’re shooting a 6.

I built a BRA after thinking the recoil diff between creed and dasher didn’t matter enough. If it’s a field-style match i’ll shoot the creed, if it’s more barricade-ey I’ll shoot the BRA. Having a good or bad mental match makes more of a difference for me than the gun either way... I probably should just build a dasher or gt and use the same gun everywhere.
