I used it some with 6.5 Creedmoor. Didn’t use it long as I happened onto RL16 and 23 and haven’t looked back. The temp stability was worth the change, but I’d use it again in a pinch if it’s all I had to work with. Had a couple buddies using it too. They learned their winter loads are way fast or over pressure in the middle of the summer once things heated up. Once adjusted thing were good again.
Running a 105 at 3210fps and the barrel hasn’t even finished speeding up after only 60rds… I hope you’ve already ordered your next barrel, because you’ll be lucky if you get 1000rds out of that one lol.
Plan on shooting the Berger 105BT and the 87vmax do I need to get a different seating stem if I have the Redding type S micrometer seating die for either of those bullets?
What speeds should I be shooting for with the 105BT out of a 1/8 22”?
What speeds should I be shooting for with the 105BT out of a 1/8 22”?
I’d pull your seating stem and check the fit with the bullets… you might need a VLD seating stem, but you might be fine with the one you have, just make sure all the seating force doesn’t end up pushing on the meplats because that can cause lines to be left behind, or worse, fuck up your BC.
For speed, IMHO pushing a 105gn bullet faster than 2950fps out of a 26” barrel doesn’t do much besides shorten barrel life. So in a 22” I’d be looking for ~2850fps with a 105, something in that neighborhood.
YMMV.
I know its a price for speed but I'm ok with that. We dont shoot long strings it will get a little weekend work here and there and be a whitetail hunting rig. It should last a little while.
Check Rifleshooter dot com. Search for 6mm Creedmoor load data. I have tried several loads out of my RPR and they shoot very close to what he's published. Of course, work up and watch for pressure signs.
I just confirmed a new load using 41gr N555 with 110 A-Tips out of a 26” barrel. It was slightly disappointing that this was on the low end of the powder range I’ve been testing for this combo, but I’d rather lose 120fps for this kind of consistency.
2950 is where most guys run the 6cm in comps with heavy bullets. Plus you get some extra barrel life, and hopefully the tune stays together longer. Nothing wrong with that. My 6gt will run 2950 with 115s but I run 2850, my bra will do 2940 with 105s but I run 2850. Don't sweat it!

I agree. The guys who are still trying to get as much speed as they possibly can before they hit pressure are just killing their barrels prematurely for no good reason.
I've throttled back to a leisurely ~2900fps in my 6CM (and ~2800 in my 6GT), and have never shot better.
IMO seeing more and getting more feedback off impacts/misses far outweighs the tenth of a click or so in trajectory/wind one gives up... not to mention getting a lot more mileage out of a barrel before it's toast.
Bottom flyer opened the group to .790 I think. The A-Tip load was direct from the Guns & Ammo article about the rifle when it first came out. 41.1gr of H4350 loaded to SAAMI.
This is out of a new Custom Shop RPR. Temp was 96F, wind was negligible, elevation about 3K feet.
Surprised by the factory ammo but nice to know factory ammo actually does shoot well. First experience with that happening.
Dogtown, this is very similar to the results I get using 41.0 grains of N555 with Berger 109 LRHT bullets. Very low SD and 1/2 MOA accuracy. Out of my 26" X-Caliber barrel, I get 2963 fps, using Peterson LRP brass and Federal 210M primers. I initially wanted to push it harder, but I agree with @CK1.0, that it's just not worth it.
I've been running 110s and 115s around 2900 out of a 6 Creed for years now (with H4831sc). Super consistent and really decent barrel life. I pull the barrels from match use around 2000 rounds but all of them have kept shooting great to 2500 and past.
Glad to see those results with N555 as I just got a 4kg of it.
I ended up using 43.5 grains of staball 6.5 and 112 barnes match burners.
My average velocity is 3055.
Thanks again for the help
What’s everyone’s go to powders for 87 V-max? This will be a winter night time hunting cartridge. Velocity is important to keep it as flat as possible but still group well.
I have either a 24” 1/7.5 twist proof barrel or a 22” 1/8 C6 barrel. Hoping to use the proof for the added velocity.

I shoot the same charge but in Hornady brass to get rid of it. I’m running 3075 but it’s accurate
Yes sir. I shot mine again today testing some BSD and have about 450rds down the tube now. It’s speeding up a little. Today I averaged 3123 over 35rds shot. It’s still hammering though. Shot this .953 at 300yds.

Getting back into a 6mm and need to decide on a bullet. I'm tired of playing whack a mole on components, so looking for some advice on a bullet in the 105-110 range that is 'usually' in stock? I generally shoot Berger LRHT in my other calibers, but they are hard to come by. Seems that the 105 HT and the 108 BT target are in stock many places. What bullet do you guys like in that range that is generally available? Application is target and some matches.
I've had really good luck with Barns Match Burners 112's
I'm shooting them out of my 26" Proof SS at about 2950.
Great BC and they seem to be more avaliable then Berger.

The Hornady 105 BTHP has been the most available from the places I look. You can almost always find them somewhere online. The BC isnt as high as many, but I have had good precision from 6 Creed and Dasher. The reasonable price is a plus also.
The Sierra 107's, Berger's 108's and the Hornady 105 bthp are the easy button. Not as fussy about powder or jump.
And you can find them more often. Plus they shoot great.
The Newest and highest B.C. bullet isn't always the best to shoot.

I shoot steel and have been reliably able to get 110 A-Tips and 95 VLD Target for the past couple of years. 105 Scenar-L has been a good option too, but I’m seeing them less frequently.
If u want something always in stock go with the 110 atip or the berger 108 elite hunter. It's the same profile as the 109 hybrid but it's always in stock.
I'm with @Shootnstraight and @J McGriddle...
I've shot about 5K of the 112 Match Burners over the last couple of years in 6CM and 6GT and they've been great for me. Getting .300+ BC for less than $0.30 per bullet is great on its own, but being able to score a whole bunch of them from the same lot is a huge reason why I've stuck with them. I've had 2 or 3 barrels that only saw bullets from a single lot from their first round to their last, and my reloading/shooting improved quite a bit because of that.
I've still got a few thousand 112MBs which I'll be continuing to use in 6CM, but will be moving to the Hornady 105BTHP for my 6GT (since the 105s are shorter and will work better with the stock 6GT SAAMI freebore). I've shot a few hundred of them and they also seem to be great (and not just for the money). As far as I can tell, the Hornady 105BTHPs do everything 105 Hybrids do, except a MF'er can actually get them.
Yeah, Bergers and A-Tips might be more consistent, but they cost double/triple per bullet, and good luck trying to get more than 500 at a time, let alone 2000-3000 from the same lot like I like to.

Another vote for 112 matchburners. Gave me way less trouble than DTACs and cheap/available to boot.
Alternatively, grab 2k of whatever 105-115 bullet you can get when your barrel is ready and just run it. Lots of good options if you can do one bulk order and not worry. I have 2k barts waiting on the next barrel, and given what I’ve seen, that will probably cover the effective lifespan.

.28 per round is very persuasive. 
Believe I will give the 112 MBs a try, thanks gentlemen. SAAMI freebore .183 ok with those?

Yep, the stock/SAAMI .183" FB works great, especially since the 112MBs like to jump (I run mine .100" off).
Sierra 107smk has been the most readily available of bullets that's are extremely consistent within their lot #s. New 112 Barnes are much more consistent than when they first produced them. Anything 6mm Berger hybrid is extremely tough to find on a shelf, 105 109 108elite. The 108bt Berger is probably one the best accuracy bullets that can be had off the shelf, they shoot amazingly but the BC is lacking compared to previously mentioned. The 109 eldm is also a very good bullet, bc of around 288 in my testing to 1200y. 115 dtacs are also available, but they need a lot of freebore to not be crowding powder space depending on your cartridge choice. I shoot 115s in my 6gt, they shoot really well from 2820-2850. 6bra I shoot 109s and 105s. The womans gt shoots 107smk, my 6cm hunting setup is 108 elite hunters, and recently did a 24" hunting 6gt with 112mb at 2910 and they're shooting very well. I have spent a ton of money on 6mm bullets and have 2+ thousand of most varieties on the shelf, so it's like get a barrel, pick the bullet, and shoot that stock till the pipe is gone. It seems now 6.5mm bullets are easier to get than 6mm, wasn't that way 5 years ago, but it sure is now!
The 108 bthp is a great bullet. I've shot it for a few years now and I have nothing but great results with it.
.28 per round is very persuasive.
Yup. 30ish k off was where I had run them, but honestly it was probably noise as they run pretty well at 100-120k as well.
I don’t think there’s a real reason to not run a standard chamber/freebore in the 6CM. It’s pretty reliable when you stop trying to toss 115s at 3200fps.
The match chamber FB is .183 , What is the FB on the standard 6CM , I read or say a print of a reamer that said the FB was .104 ?
Is that correct ?
Is that correct ?
That is what Pacific Tool list on their MATCH reamer, on their "standard" reamer they list .109
Found the problem.
A good smith should have a saami spec reamer, or if you have to own one get it from jgs or Manson instead of a PTG disappointment.
I just measured both and the 112s are a little longer in length, but have a shorter base to Ogive. 112 is .685” and the 105 .720”.
You will have no problems running the 112s in the GT. I ran DTACs and they are longer and a lot more BTO.
I've run thousands of the 112MBs in 6GT and they hammer, but I still don't like not being able to jump them as much as I'd like to.
The 112MBs in a .120 freebore 6GT are on the verge of having the bullet's bearing surface below the shoulder/neck junction at only ~.010" off.
The 105s, being shorter, seemed easier to deal with in the shorter freebore IMO. But, maybe I'll take a closer look at it, it could be that I just don't like a short freebore with a SAAMI 6GT chamber..? YMMV.
The Hornady 105 is going to sit about .035” deeper in the case from touch than the 112 even though it’s shorter in length.
112 MB .685” BTO
105 HPBT .721” BTO
112 MB .685” BTO
105 HPBT .721” BTO
How far off the lands do yall run the 115 DTACs? I started with a box of them because they were more available than Bergers, but I've been having trouble getting a decent load figured out.
So far I can't tell if its the barrel speeding up, the brass fireforming, or issues with the bullet. I'm 100 shots into a new build and only halfway through my lot of 200 pieces of brass. I did a charge ladder to get up to about 3000 fps, then shot some 5-shot groups at various seating depths from -.020" to .060" and nothing really stood out to me.
