6mm Creedmoor

[Nick Caprinolo]

I have been thinking of a new project lately and have considered the 6mm Creedmoor. I would like to shoot heavy bullets as it gets windy here sometimes. Been thinking of 8 twist barrel.

Question is what is a good bullet weight? What powder and what primer?

 

[Emmett Dibble]

8tw will stabilize sub 110gr no problem. 7.5 if you want to go 110+

Howdy !

What will be the application for the rifle ?

And...... what distances are you likely to be shooting over ?

@ Nick,..
The 6XC will get you, a Few Hundred, MORE Shots, of, Barrel Life, IF you can live with, about, 100 or so FPS,. Less Velocity. I went with, the 6 XC Tubb, Version One, Criterion, 1-7.5 twist, .104 freebore, 24" Barrel, Forster Dies, Norma Brass and with, 107 Sierra's, am getting into. the LOW, 2's. Am now, working on, 103 ELD-X's for, Yotes.
This Combo shoots Everything from, 80 gr. Varmint Sierra's to 108 gr. Elite hunters into SUB, 1/2 MOA,
The Stiff, Heavy Sporter, .707 Dia Muz, 24" Barrel, Hits the exact SAME, POI,.. every Week !
It's, a carryable Predator Rifle at, 10 Pounds, Braked all Up and,.. a Joy to, shoot.
Good luck and have Fun,.. you'll Like, the Fast / Accurate,.. 6 MM's !
AND,..the 6 XC has Won, MANY, 1,000 Yard competitions as, IT's,.. a VERY, accurate, Cartridge.

100 to 600 depending on the range I go to.

 

[spudgun]

On 600 to 1200 yds, I have had very good luck with 105 ELD's and H4350, running 2950 - 3000 FPS.

 

[Drop Port]

If you are not using it for serious competition and want easy, get some 107 SMK's and 108 Bergers and see which it likes. Neither are the most sexy on the market today, both can hold their own. Have you considered a 6BR with 105-108's?

 

[Rob01]

I would go in the 7-7.5 twist area. I have used 7.7 barrels and they work great with the 108s. My newest barrels are 7 twists and I shoot the 110 ATips and they do very well. The 8 will actually work up to the 115 DTAC but a little more twist doesn't hurt.

 

[Ranger188]

If you are only shooting out to 600, more speed will also work. (lighter bullet)
A 8 twist will work with any bullet you want. 7.5 will work with the 110-115g in less than ideal conditions.
I'd also look at 6gt or 6xc even the 6x47L
All with less powder and just about the same speed.
Bullets are coming around (.243), but brass and dies can be a deciding factor still.
Used CCI450's
RL16 will give you a little more speed than H4350 and not pressure out as soon.
Both are the gold standard.
You can run the 95g bullets faster and get less drop and about the same drift.
I've had great luck running 110g and 107g Sierra's. The 110's are a little picky on tune.
The 107's are the easy button. Lot's run the Berger 105 hybrids.
Just get what you can find the most of and shoot them.

I have a 6 Creedmoor in an RPR and a new GAP. They both shoot really well with Berger 108s as well as Hornady 108ELDMs. I've also tried Sierra 95 TMKs and 107 MK's also with good results. Groups typically open up a bit with Hornady 105s. I've not tried the Berger Hybrids. The Ruger barrel shows some serious fire cracking as it's still on the original barrel from 2017 but still shoots under moa at 200. My best groups was with RL17 pre-Covid powder shortages.

 

[JB10]

Mine is a factory rifle with a 1:7.75 twist. Im shooting 108 eldm at 2,955 fps with H4350. I also tried 108 bergers. They shot good but wanted a little cheeper bullet so i could shoot more. Using federal 210 primers and ADG brass. Smooth shooting cartridge in my opinion.

 

[Rob01]

I'm using H4350 and Fed 210 primers also but with Hornady brass.

 

[urbanrifleman]

Barnes 112 shoot amazing in my 8 twist. I have them in stock for 35 bucks.

 

[Hoot]

A powder you might not think to try with the 108 ELDM's is RL26. Late last fall, I loaded up 5 for my 6CM in an RPR chassis running a barrel from urbanrifleman and proceded to put all 5 into a .096 group at 100 yds. Bum luck? Maybe, but I intend to try it again once comfortable shooting weather returns in a month and a half. Had to really fill the case however. Averaged 3300fps with a single digit SD to boot. At the same range session, it shot a .183 group with H4350 as well and a .143 with of all things AR-Comp. The latter two running around 2930fps. Not as lucky with TS-15.5 however.

YMMV

All and I mean ALL my best loads are compressed to some degree.

When SPENDING, a Bunch of Money ( $2,200 to $3,500.00,.. all, Up ) to, Build a 6 MM,.. Target / Varmint Rifle,.. personally, I'd look for some, descent, Barrel "Life" and the 6 XC does, THAT, Plus it, Feeds WELL, in a Short Action,.. Hence WHY, the 6 XC was My "choice" and believe me, I did, a LOT of Reading / Studying, before making, that choice.
IF you're, a LOW Volume shooter ( Predator Hunter ) , the 6 Creed is Fine, but the XC will give, you MUCH Better, Barrel Life ( If, you enjoy, Ringing Steel and Target Practice ) with only, a small Loss of, Velocity.
From My studies, the best Twist is from, 1-7.5 to 1- 8, covering most of, the Popular Bullets ( 80's to, 110's ).
StaBall 65 Powder, with THROWN charges, works Amazing, in my 6 XC 1-7.5 with, 95 Bergers, 103 gr. ELD-X's, 107 SMK's, 108 gr. Berg's & ELD-M's

Nick,
If you proceed with the 6 Creedmoor, contact me, I have a lot of 6 Creedmoor stuff to sell, Brass, Redding bushing sizer die, Wilson Seater. Laupa brass, even some loaded factory ammo. I am just over the line in PA.

I will do that. Still thinking about building it. I have a Remington 700 action here waiting for me to make up my mind an the next build.
Thanks

Had two 6mm Creed rifles both went a bit over 1700 rounds and they were still shooting fine when I pulled the barrels.
I was using 105 Bergers, Barnes and Nosler Rdf's. I found the round was very easy to load for almost like you had to work hard to screw it up.
I mostly used H4350 and IMR4831.
600 yards is easy street for a 6mm creed. Yes barrel life is short, no free lunch here.
