Best 6mm for the dollar

My problem with Dasher is that you can't use a aics mag without mods. 6x47 is also what my friends are using
like Dthomas said...drop in a primal rights BR mag kit and done...add an MPA+4 and you have a 15 round mag

And if you run a 7.5 twist you are probably closer to .280 and with a 7 twist I got a verified .286 g7 with AB's mobile lab.
I saw them run over the AB Doppler with a 7.5t bartlein. Average BC was like .275. The BC consistency was 3x worse than the average Berger 105 I saw too. The 115 rdf I saw was 305ish. It’s all on the PDMs uploaded, you can download them if you have a kestrel w/ AB and see them all.
Runs 100% for me in a 700SA with Pmag 7.62AC.
Hell, 6BR runs 100% in a Nucleus with same Pmag 7.62AC.
I started a thread about this basically...how can you get a verified G7 on AB's equipment that is 11thou higher than AB's own test (and Berger's spec)?
And once AB measures that, why don't they update AB Mobile to reflect the new higher (or lower in some cases) measurements instead of having a dozen different profiles for the same bullet?
The BC variance in the same bullet is...startling.
im not sure what you mean about spinning numbers up im trying to run numbers equal...running one at 2900 the other at 3000 is not a fare comparison.
im with you on the short neck...BRX is the same way but ive shot so many small groups its hard to get away from.
im going to play with the BRA here shortly....JGS reamer ships next month so i should be up and running end of november first part of december...i dont really want to run 4895 so if i can get 2925-2950 with varget ill be pretty happy.
also ive given up on the hybrids...the last 3 lots ive played with all true out different...276 300 and 310...i love the slippery little hybrids but the last 3 lots of 108 BTTs have all trued out close enough to the same that it doesnt matter plus they are super friendly and consistent.
as far as barrel life...its a crap shoot...when i shot a 260 i had a barrel go at 800 rounds at 850 i pulled it and sent it back to the manufacturer and they replaced it....then i had one go 3000.
6mm barrels...i had a 6CM at 3050-3075 its entire go 1700 and the one i just shot at 3220 go at 758....most 6mm barrels ive shot go 1200-1800 depending on how they are run and the shooters accuracy expectations.
you really need a 100 rounds through a barrel to start load development anyway so fire forming really isnt a big deal plus after you shoot out the first barrel you keep it for a fire forming barrel...or just fire form at the end of each barrel.
ive shot 200 rounds of his and 120 from DJs...both GTG.
I started load dev for my 6.5-284 Norma after 25 rounds. And its still holding 300+ rounds later. 100 rounds is excessive.
I know the jury's still out, but I find it notable that the 6GT addresses a lot of the concerns with other 6s discussed here. Neck length, mag feeding, fire forming, shoulder angle, powder capacity.
no a 100 rounds in a 6mm is not excessive because thats where the barrel speeds up...ive shot my break in and started load development in a couple of 6mm barrels and it never works out i always end up having to do a mini LD.
im watching and waiting but until i see something impressive and better brass ill stick to the tried and trued BR cartridges.
With all due respect to George (he's forgotten more about rifles and shooting than I will EVER know), I'm not sure the 6.5 GAP 4S ended up being the game'changa that it originally was proclaimed by some folks here to be.
With that experience in mind, I'm a little bit skeptical that the 6GT will end up being all that and a bag of chips (as some here are proclaiming it to be), with all of the pros and none of the cons and compromises of other popular 6mm chamberings.
Then again, I'm sure plenty of folks thought that about 6.5 Creedmoor over 260, too.
***If*** Hornady starts offering factory 6GT ammunition, THAT would be huge for the chambering (much like Hornady's strong support of 6.5 Creedmoor was) though it would surely cannibalize 6 Creedmoor sales.

If you are already invested in BR, that's a good idea. But I think someone starting from square 1 would benefit from observing the 6GT results closely. I'd love to have a dasher or bra, but fireforming, hydroforming, etc sucks. I like open box and load brass. Long term Alpha brass availability for both GT and dasher is unknown, so that's something I'll be watching as well
i get the fire forming thing but its really not a big deal...use it as practice time...as far as alpha brass goes ill pass ive seen the issues with it...also like boiler up said i really dont think the GT is going to be the dasher killer its being made out to be and i doubt hornady is going to cut their throat with it over the 6CM...but then im wrong more often then not...i guess time will tell.
I have shot almost every 6mm mentioned in this thread.
6 Comp Match
6 SLR
6 Creed
6 XC
6 X 47
243
Dasher
6 BRA
I think I will always shoot a 6 x47, and a BR variant, most likely 6 BRA. I have had great barrels in all of them. Not sure what it is, but when I want an accurate rifle built, I seem to always come back to cases designed by Lapua.
Barrel life is a crap shoot with 6mm, I have seen 2400 accurate rds from a 6 Creed, and only got 1100 from a 6XC. I also got 1800 from my first comp match, the next barrel was going downhill at 600 rds, made it to 1200 though. My first Dasher barrel looked terrible with a Hawkeye borescope at 600 rds, at 1400 it is still shooting for now.
That said, I like your choices, when you ask a question like this and get 50 responses, at some point, all are subjective. For every 3 people that love the XC, there are 2 that will never revisit it< Example
I doubt they did, I recall 6 BR Remington, but for a couple decades Lapua was the only brass maker, Sorry for the confusion.
A big question that could make this easier. Where do you live?? I live in the south east. Wind is nothing. I shoot a BR and im good. My two shooting partners shoot dashers with 95gr SMK's without wind problems. If you live in the midwest or out west, wind comes much more into play. A lot more prone shooting out there. Here, its more about positional shooting and spotting trace/impacts/misses. BR based cartridges are king for the reloaders. That isn't to say that BR based cartridges aren't applicable out west b/c obviously, there are tons of shooters out there rolling with BR family rifles. That may be something for you to consider
i think my smith runs the MDT mags...im stacked with the accurte mags so i just run them.
this is a great point...i love the 6CM because i can run it real fast and not worry about wind and if i had unlimited barrels it would most likely be all i shot...700 rounds and spin on a new barrel.
do you practice? shoot matches? fireforming is basically just shooting a 6BR...nothing to it nothing hard. not even a waste if you're shooting anyways learn the wind
i bought an extra kit and cut the spacer to fit in +4...6BR and BRX both run flawless as fast as you can run the bolt.
we are twins LOL...i will go out some times 3xs a day...i shoot at least 125 rounds most every weekend...ive been in the same trade for 32yrs and work 11-12 hours a day so weekends is it for me...im at my loading bench 3x a week doing something.
Agreed. I shoot so I can reload. If I werent reloading I would just be a crotchety alcoholic hermit with a netflix problem. The difference is I produce something when I reload.
I was shooting slow partially hydroformed 6 dasher brass at the Altus PRS match a few weeks ago and tied for second. I probably should spend more time reading on the forums to prep for the finale. I could've saved myself a lot of time and powder knowing what I know now.
Lol, I used to consume beer like oxygen, turn 15+ peppermills or bowls at 50+ per a month and give away. Shooting 4 times a week and reloading 4K rds of LR rifle per yr just makes more sense for myself.
Have to say, reloading is getting old after 33 yrs. Pistol has been out, and I find myself buying 223 ammo today, thank God I can afford to.
This is the bottom line and really all that matters. It's kind of like muscle cars.....Good, Cheap, and Fast you can pick two.
Good Barrel Life, High Velocity, and Low Recoil - Pick two.
Good Luck,
Ross
I live in Kansas but most of my comp shooting will be at k&m in Tennessee
I'm bringing a 6BRA to the PRS finale at K&M in 2 weeks.
Also shot 6BRA at our PRS Regional Finale out in the Pacific NW last weekend, 15-20mph winds, a bit of rain/snow and cold temps. 2910fps with a 105 hybrid, finished one point back from winner in a tie for 2nd.
27.5" barrel, 105 hybrid, 30.4 of H4895, 2910 fps or so.
I’m sure I missed it in some of your posts.
Why the change from dasher to bra? Anything in particular?
