6 Competition Match Performance

[JigStick]

Having an extremely hard time deciding between the 6 Dasher, 6x47 Lapua, and 6 Competition Match. Dave Bruno is building the stick for me on a Stiller Tac30-AW action and McMillan A4 stock. Plan on using the rifle for PRS matches and shooting 0-1200yds (which I do weekly).

Feeding from a detachable magazine is critical for me, and I believe all 3 will do it. So its basically coming down tuning preference. To shoot 105-115g pills, which do you think will have the most inherent accuracy? Dave has told me that ALL of them can be super accurate, but that the 6 Dasher is going to be the easiest to "get dialed in"

What say you?

Try the Dasher first in a 1-7.5 twist barrel.. Then build a 6x47L if the Dasher has to much hang time for you as it goes down range.. It wouldn't be much but around 50-150fps if using H4350..

I personally would be worried about feeding issues with the Dasher. Based on a little experimentation I have been trying myself. I would choose the Competition Match myself. Interested to see what other responses you get. Good luck and have fun with whatever you choose.

I've have been shooting the 6mm Comp Match in PRS about 4 years.
Win .243 brass neck turned to .013
RL-26
Any 105 bullet
Feeds out of ACIS mags.
3200fps from a 24 inch barrel
The load is easy on brass
Vertical dispersion is 1/2 MOA @1000y

I helped R.O. the Accuracy International Long Range Classic at Core Shooting Solutions this past weekend. Joe Walls runs a 6 Dasher, it did as his own exact works "runs like butter"..... I would stay away from the 6x47 Lapua. I'm a 6 Comp lover, fixing to pull my barrel, finished 3rd at Volusia County Gun Club tac match 10 days ago with 4589 rounds down it, ALL with H1000.....Shoulda, coulda had 2nd but messed up the mover stage. Joe Walls pulls his barrels at 1800 rounds, Joe Hendricks pulls his at 3800-4000.....

Why would you stay away from the 6x47 Lapua? Apparently it feeds excellent from AW and AICS magazines, shoots faster than a 6 Dasher, and can give it a run for the money in the accuracy department if tuned good.

FWIW my buddy is having a hell of a time tuning his 6 CM at the moment. Has tried 3 different bullets, 20 different powder charges, and changes in seating depth....and it still doesn't shoot as good as his 243 did. Both barrels chambered by the same gunsmith.

He's got a problem somewhere else, it ain't the cartridge.

That's your opinion about the 6x47 giving the 6 Dasher a run for it's money in the accuracy department.... I have my opinion on just how accurate the 6 Competition Match is. I know how it runs thru mags. I also know it can be faster. For PRS and out to 1200 the 6 Creed would be nice or the 6SLR.

Sorry, came back to answer your question. I have never shot the 6x47 , but from talking to shooters and reading on here that they can tend to be finicky to get a good load for. My 6mm Competition Match barrels have shot break in f.f. groups at 200 yards you could cover with a dime.... 5 and 10 shot groups....

 

[JigStick]

Well I live about 30min from Joe, and he actually shot with us last weekend. and even he was kind of stumped at why my buddys 6CM wasn't grouping good. Anyways…its put a bad taste in my mouth regarding the caliber.

I definitely think the 6x47 would be the better choice, over the Dasher, if I was going to be using 115g projectiles. But if I were to use 105s….I would give the edge to the Dasher. This is like splitting hairs. Im going to flip a coin and run with the result.

 

[Dgd6mm]

You obviously know more about it then I do. The way you guys shot you wouldn't have a problem shooting any cartridge. That competition match sounds like it needs to be looked at, I have never heard of one that would not shoot.

I was the score keeper on the rack n tower. And in the two days I witnessed some very good shooting.

Have run the 6mm Crusader for 7 years now (6mm Rem. blown out). Longer neck, slightly larger case capacity, same slow powders as the 6mm Competition Match. Basically all of the same things that are being attributed to the supposedly super long barrel life. I have a real hard time believing the barrel life numbers being quoted for it. I've used the same bullets and powders (51 gr. H1000, 52gr. Retumbo with a 115 DTAC). I'm probably running at a slightly lower pressure due to larger case capacity, and the longer case neck should also help with barrel life. All of my barrels have died between 2100-2400 rounds. I consider them dead when I start getting vertical at distance. They could have still held a full IPSC at 1k, but I wouldn't want to try my luck on a 1 MOA plate or a KYL rack. Maybe they live longer if you chase the lands, but with the 6mm Crusader I can't do that and maintain mag length. I'm pretty skeptical though that it would give twice the barrel life even if I could.

Shot the 6mm Crusader at the GAP Grind. Switched to the 6x47L for the CORE AI match. I personally had no trouble tuning the 6x47L. It shoots, even with virgin brass. However, I designed my reamer with generous neck clearance (0.276). Many of the reamers I looked at had very little clearance around the neck and I would not consider them no-turn with the 6x47L brass I have. Some necks are nearly 0.271 loaded and some of those reamers are 0.272. I believe this is why some people find it hard to tune. The little bit of peening on the factory case mouths is enough to cause interference if not fully removed.

Looked at Joe's 6 Dasher round while I was waiting to shoot the bus mover. Nice little round, probably has very little recoil. Something I would be interested in if I could buy brass or just size another case down. Not a fan of forming brass anymore. Have done it for long enough with the 6mm Crusader. It gets old, and it isn't much fun when you discover that half your brass needs to be scraped and you're scrambling to form new ones in time for a match.

My buddy FINALLY got his 6CM dialed in. He switched to the Berger Hybrid seated back 8 thousandths and it shot a 10 shot ragged hole at 100. Dam did he have trouble getting to this point. The hybrids tuned much quicker than the regular VLDs. Based on his experience I think ill be leaning hard towards the 6x47...but the 6 Dasher keeps coming into my mind. I need to put both into Quickloads and see the wind hold differences between the 115s out of the 6x47, and the 105s from the Dasher

 

[MOShooter]

I've heard that the 6x47 can be tricky to keep in tune. Ive shot with a guy who runs a dasher in PRS matches and has no trouble. I don't know much about the 6 comp match. I've been running a 6SLR for the last year. Almost the same as the 6CM but no fire forming. Brass is easy to find which is currently a problem with the 6x47.

Before I'd go 6x47L, consider this...the 6x47L is a great round however it can be finicky b/c folks want a certain velocity (usually 3k fps)and this cartridge boiler room is just at its max if not it's upper threshold for that speed vs pressure with 105s. IMO this cartridge is best suited for 2900-2950 fps without pressure spikes due to temp., fouling, and other Conditions and keeping pressures in check with great shot to shot consistently.
IMO these come to mind that are very forgiving and have a wider tune ability as conditions change (No particular order)
6xc. 243 win. 6 slr. 6CM. 6creedmoor(borderline)
6.5 creedmoor. 6.5x47L. 260rem.
U notice that all of them have very close same capacities and why they are widely used in PRS. I've personally still shoot 243win, 6xc, did shoot 6CM (I have that reamer and go gauge for sale if one wants)
And I used to shoot 6x47L too, so yes i have personal experience with quite a few of these rounds. So if u have a velocity pre determined in your mind and it's near 2950-3k, I'd shy away from 6x47L and look at the others..
Good luck on your Endeavor...this shooting stuff gets expensive really quick..

I have all 3, Dasher hands down.

 

[JigStick]

I know guys pushing the 105 hybrids over 3100fps out of the 6x47 with no pressure problems at all. So that is interesting.

Doesn't seem like many Dasher shooters are spitting the 115s. I'd like to hear from somebody that is

 

[Dusty Stevens]

Why not straight 243? Good or cheap brass, feeds like butter,and good velocity. Its just not the "in" thing these days.

I'll be firing one up shortly.

 

[tbeasley]

I'm with Dusty
Straight .243 Win. is what I use in Pierce short action feed by PTG stealth dbm and using AI mags. Went with a 1-7.75 twist Benchmark and shoot everything from 70gr bk thru 115dtac bullets. It just loves 4350 powder. Just make sure u use a short freebore.
