Dasher vs BRX which is more accurate?

[JOHN708]

Is one cartridge more inherently accurate than the other or are they about the same?

Hello John... I know people who have a Dasher and some who have a BRX, they BOTH shoot excellent! It is doubtful you will ever tell the difference. I currently have a straight 6mmBR that once the barrel goes, I will re-barrel it to a BRX. The ONLY reason I will do that is because I like the longer neck of the BRX.. It is strictly a personal opinion on which cartridge to opt for over the other.. Both will do everything you ask them to do!

BRX has a shorter neck than a Dasher.... The BRDX has a longer neck than a Dasher. Check the records that will tell you but the quality of the barrel is the final factor.... jim

 

[ShootDots]

You are correct Johara>>>I stand corrected>>>the other "item" that makes me want the BRX is the same shoulder angle as the regular BR... The "BR" family is probably the single most accurate "family" there is today... Keeping almost everything the same somehow seems appropriate to me.. But as I stated earlier>>>It is doubtful one is any MORE accurate than the other...

I don't know if you could get a rifle to shoot better than the two i have now but there is more to it than shooting small,both shoot in the mid zero's at 100 yds. A hummer barrel shoots in the wind, maybe not as small but it will shoot smaller at 1K. These two Brux barrels shoot like PPC's and they are Dashers but i wish they were hummers....... jim

Has anything changed? I'm in the same boat, between Dasher and BRX.

You'll find fanatic devotees of each.

I run a BRX, and I am very very happy with it. I chose the BRX because my smith had experience with it, and already had the right reamer and dies. If the situation had been reversed (dasher), I would have gone that way, and I'm sure I would have been equally happy with it.

IMO, It's much more important to find a good smith who knows his stuff, and to do your reloading homework, than it is to argue the merits of these two almost identical (in practice) cartridges.

Not enough neck on the BRX, you are at the mercy of the free bore. This makes the Dasher more flexible and the BRDX even better......... jim

I'll call BS on this...

How is this unassailable fact? How long does a neck need to be?

You may prefer the longer neck of the dasher as a matter of preference or opinion, but it's exactly that: preference or opinion.

I'm a member of Piedmont Gun Club in Rutherfordton NC and work the shooting line during matches and in my opinion i don't see much if any advantages between them . I also work with target crew pulling targets so i get to see results up close i pulled Rodney's record target and he was shooting a Dasher also there when Chad Jenkins set Light Gun record agg of 1.4 for four targets shooting a straight BR. Terry Brady as well as Sam Hall have set and broke records with a straight BR there, so i guess it's like ford or chevy just what ever gives you the confidence you need to compete. Advantage with straight BR is less work on brass and my opinion less place to screw up already expensive componets and have to buy more equipment, just my observation and opinion.

 

[JOHN708]

Good responses guys! What I was looking for is whether the shoulder angle, 30 vs 40 degrees makes a difference regarding accuracy. Apparently not so much. My gunsmith thinks the BRX is slightly more accurate. Maybe. I kinda think it's a toss up. While we're on the subject I'm not sure how much case neck length effects accuracy. An interesting experiment would be to take a BR, shoot 5 5 shot groups with your best load then repeat the process using the same cases with the necks trimmed back to 6 BRX neck length, along with the same cartridge OAL. If I currently had a 6 br I'd try it to see what happens.

[johara1]

I think you guys miss the point on the neck length. It limits the bullets you can use with your free bore length and that ain't BS. ...... jim

 

[JOHN708]

Correct. But many individuals tout the longer case neck as an aid to accuracy and I'm not sure it's valid. Some one show me the research on this.

Can you elaborate?

My BRX barrels were chambered with the 105 hybrid in mind. My bullets seat without having the bearing surface extend lower than the neck shoulder junction and I have plenty of room to play with seating depth with that bullet, even as the throat moves out...

I guess I can see some potential validity to your argument if one wanted to shoot bullets with vastly different lengths; that a longer neck might prove more versatile. However, I think that a hypothetical advantage at best.

Here is my load46.6 gr H4350 30''barrel with 105 berger hybrid 3085fps. To load this you must use a long drop tube with a slow pour. Good Shooting Larry

Larry:
Did you mean to write 36.6 gr H 4350? I sure hope so because I couldn't put that much of "anything" in my case...........hahahaa

 

[ridgeway]

I have taken the 6mmbr in the brx chamber out to as little as .150 neck and also the dasher .150 neck. from what I have found the all will shoot . my choice is the dasher just because you don't get the case flow.The reason I did it was to try slower burning powder . Varget, RL15 all burn where you get 90% of your velocity in10'' of the barrell H4350 burns where 90 % of the volocity in 17'' .I get the same speed with 1500 psi and spread the heat over 7'' more barrel by using H4350 .So far my test is proving my throat wear has ben reduced to almost nothing.Here is my load46.6 gr H4350 30''barrel with 105 berger hybrid 3085fps. To load this you must use a long drop tube with a slow pour. Good Shooting Larry

How are you calculating powder burn in X% in X" of your barrel?

 

[ridgeway]

Oh ok...that's simple enough.

 

[JOHN708]

H4350 usually isn't as accurate in the BRX as Varget, R-15 or H4895. If it works in your gun it will give you 3050-3150 fps with no problems.
