Home Forums Hunting & Shooting Custom Rifles & Wildcats 243 or 6mm Creedmoor for build?

Go 6 creed. I have multiples in 243 and 6 creedmoor.

The 6 creedmoor will fit your mag box with high BC bullets much more easily. Factory ammo here in the US is easy to find for it as well. As others said I'd think about a 7.5 or 7 twist. Mine are 8" and work fine with every 105-108 grain bullet I've tried but as it was mentioned, bullets keep getting longer

I have heard that the Creeds barrles last longer.. Any truth to that? Also, when I do burn out my .243 WIn. barrel, can I get the barrel reamed into a 6mm Creed??

6 Creed with 1:7.5 twist. Shoot the 105 VLDs if you reload, or the 103 ELD-Xs if you don't.

Very, very easy button. Only this most recent hunting season for data, but it shoots like a house of fire with the 105 VLDs and accounted for two bucks and a bull with zero drama this season.

Barrel life between them is more dependent on how you shoot them than the difference between the chamberings. Both are usually cooked somewhere between 1500-2500 rounds, depending on how they are shot and loaded for.

If you have enough shank, you could set back the barrel and re-chamber in 6 CM, but you're better off to just get a new barrel and chamber that in 6 CM.

The easy button is 6 CM in a 7" twist barrel. KS Arms will build you the barrel you're looking for.

Both of my Grand Daughters are shooting 6 CM we converted from .243, it would be hard to talk them out of their rifles they have killed everything they have pointed them at with 108 gr. ELD-M

My favorite Cooper .243 A.I. I call Bloody Mary, finally gave up with over 5000 Rnds down the tube I have found my .243s shoot a lot longer if I don't hot rod them with light bullets and max loads, Bloody Mary is at the Gun Smiths Now being barreled to a 7 Twist 6 CM Kreiger I'm looking forward to getting her back. my other 6 CM is a Christen Arms it shoots lights out but is a little long and heavy for a Jeep gun. Rio 7

Creed and a 1-7” barrel.

6CM gives you more room in the mag box. Mine is actually 1:8" but the rifle got stamped otherwise.

Owned a bunch of 243s. The 243 in a custom rifle build is very hard to beat. The 1-8 twist is a do all twist

Just got in an old Rem 700 Ultimate Varmint 26" that I need to finish testing out, before I tear it down and rebarrel it. If and when, it will go back on the trued and squared action as a 243 with a 1-8 twist SS barrel with threads cut .010 over in the truing process. I have all kinds of cats, just want to make this a 243 with a factory chamber.

The 243 with a good action and barrel gives up nothing to a CM and the 243 is a lot more available as a factory cartridge around these parts. I would not make a gift, that even might be a problem.

How will she be using the gun you are building as she goes forward.....say as she becomes an adult and gets into game at long range. That is where the CM shines over the 243. I was also thinking of a 6.5 CM barrel replacement for my Model 70 in 243, but my shots are 300 yards Max and the 243 gets that done for me. Low recoil like the creed, I reload my so no problem with ammo, and very accurate with what I load for. If I was shooting further and larger game I would want the creed, but that 243 has a lot going for it and I think you need to answer these questions for her future use.

He's got a shorty action.
With a 1:8 or 7.5 twist, he won't be able to get those bullets in the mag and will have a custom single shot. Least I couldn't with the 105s and 8s. If he had the long action, I'd run a 243 win and an 8 would work nice. I like the 105 berger on too of imr4350. Sucker is like a big little gun.

I mean, he'd get them in there, but will be jumping quite a bit and lose boiler room capability.

Never heard of an Ultimate Varmint 700.

What are the particulars?

Cartridge over-all length is determined by one of two factors: the length of the magazine, or the length of the throat. So, if you are handloading and have a custom chamber, with the same mag length, COAL for both cartridges is the same.
I would go with the 6CM just because I think it is a little better cartridge design. The sloping shoulder and short neck of the 243 are not a great combination. GD

If you want to get technical, a 243 win with a 30 degree shoulder and a 1.75 twist barrel would be pretty dang sweet. It's a custom build, and anytime I build something it's because A. Remington ain't chambering it, or B. Because I want a custom cartridge or wildcat with a custom chamber/throat.
Since the OP has a short action 700, it'd be hard to beat a 6 creed.

6xc or 6-250 to be different. Had to say it. Sorry lol

Fascinatingly HILARIOUS,that Day Dreaming Droolers always turn these things into a Bad Idea Tournament and GoogleFu straws to grasp. Hint.

COAL length is factored by projectile selection. COAL is NOT static and moves around more than a whole fhuqking bunch,due same,with IDENTICAL mag confines and throat geometry. Due the distinct differences in case length,between the 243 Win and Seex Kreed,COAL is going to be exceedingly different at IDENTICAL throat lengths,with IDENTICAL projectiles. The Kreed is a vastly superior mechanical design,of like powder capacity. Win/win/win. Hint.




While I've a goodly herd of exceptional 243 Win's/243 AI's,I couldn't begin to factor a reason to suffer same Today,with the Seex Kreed in the picture. A "long action" isn't going to "MAGICALLY" transform a 243 Win,into something it is not,with "MAGIC" throat geometry. Going 6-06 changes the game and I've a few. Hint.

Google Gals say STUPID fhuqking schit like this. Hint.



She's going to go L/A,then reduce RPM,which funnier than fhuqk?!? IMR4350 being a Goat Fhuqk to boot and the only fhuqking thing she "shoots",is her mouth. Then she Drools shoulder angles. Nor could she pick the XC out of the crowd. Pardon the reality of wares that exist and actually shooting same. Hint.



I've multiple 700 based Customs in Seex Kreed and reserve RPM is your friend. Betwixt CUSTOM and OEM spouts,I drive it in 7,7.25,7.5 and 8" RPM. Throats lengths vary and it is VERY easy to connect all dots in a 700,ala AICS binderless DBM at 2.975" COAL latitude. Up to and including 112's and their .620 BC. Hint.

James' spouts are fhuqking exceptional. Hint.







Now coming full circle,was shooting with The 'Horn yesterday and he had a brace of Seek Kreed's in tow,a Sig Cross rebarreled and OEM Accuracy International AT-X. I drug my rebarreled Accuracy International AT-X K&P 7" RPM 21" Dasher and did exceptionally well to the 1350yd line,which is as far as we happened to shoot. 112's at 2820fps,is a nice place to be,with it's minute ES/SD doing LR vertical favors. Trip cost me a Garmin chronograph and I've grown to hate chronographs. 60 MOA inclination left me about (3) Mil's off mechanical bottom of erector and it's a nice place to be. Hint.(grin)



Pardon the luxuries,of being afforded not having to fhuqking guess. Hint.

Just sayin'................

Nice remage barrel. Looks like a dick on a fish. Did you hack saw that one off too and give it your custom crown job?
As far as imr 4350 and 105s, 41.5 grains of that noise has taken more coyotes for me than you've taken pisses in life. Seat that bich out and fill it up.

Remage barrel......lmao

And if you need to swap a trigger, a hatchet makes a great tool for that....

Sweetheart,

The ONLY things you can talk about in the first hand,are your Homo Erotic Fantasies...you "lucky" kchunt. Hint. Congratulations?!?

I tend to chop/shoot on the fly and KNOW what's going on. Hint.






Your Day Dreaming Delusions are funnier than fhuqk! Keep "living" vicariously,as it's your ONLY move and don't "forget" that Imitation is THE most Sincere form of Flattery. Hint.

Fortunately for you,Imagination and Pretend are free,so even YOU can "afford" to "contribute". Pardon wares that exist,as you Pretend aloud via GoogleFu. Hint.





Fhuqking LAUGHING!................
