6mm cartridge choices...

6x45 aka 6x223

I am considering a build of a new long range varmint bolt action rifle and decided on 6mm. It seems like nowadays there are a lot of options.

I seem to have the following options at the very least:

6mm Creedmore
6mm Dasher
6xC
6mm PPC
6mm BR(A)
6 x 47 Lapua
6mm ARC

Doing a peruse of YouTube it seems everyone like the lates which doesn't help though 6mm Dasher is supposed to have a better barrel life than others.

Any opinions from those with experience?

I reload, so availability of factory ammo is not an issue though availability of brass is as long as I don't have to run through a multitude of steps to form the brass.

No Gay Tiger?

If per chance you decide to go PPC.

From the "reloading pay it forward thread".



The "stuff" is a never used Wilson Chamber seating die, and 2 bags of new 20 cases each. Roughly $100 worth of stuff in todays money.

I'll take that 6ppc stuff.
I have been meaning to build myself one for years.
I even picked up the reamers and gauges.
Just never got around to it.

What about the .243 Win. or the 6mm Remington (.244 Remington)?

243 is for boomers.

I once shot a 3 shot 0.95" group in 5 seconds at 600yds with my 243 though...

The ppc might not be a bad idea but you need to form brass.
The dasher and BRA are essentially the same. Making brass is simple with the bra, you just shoot 6br brass.
I have shot the ppc, bra, dasher, and 6x47. There isn’t much of a difference between them, A prairie dog will certainly never know.
The bra along with a 6br is the easy button out of those.
What bullet are you planning on using? There is a little recoil with them, it’s easy to miss the “splat”. A muzzle brake might be a good idea.

Your powders on hand will shoot well enough with any of these cartridges.

I agree the 6mm BR or 6mm PPC are the way to go.
What about the .243 Win. or the 6mm Remington (.244 Remington)?

.243 FTW

And just to clarify you can shoot the 6ppc with a 308 boltface. My Borden 6ppc has a 308 boltface.

And dont forget RE15 powder in the 6BR and 6 Dasher that powder has won a bunch of trophies.

A friend of mine shot .189 for a 3 shot 100 yard group, and .509 at 300 yards using a Berger 95 grain VLD out of his 6mm BR, so will give that a try among others.

I was also looking at:
95 grain Sierra Match King
108 grain Hornady ELD
88 grain Cutting Edge MTH

Everyone's definition of "long range" varies, but among the PRS guys who shoot 6mm, the top 3 most commonly used bullets are:

David Tubb 115 grain DTAC
Hornady 108 grain ELD-M
Berger 105 grain Hybrid Target

[W.R.Buchanan]

I'd look at the .243 Winchester.

There's a good article on a AR10 in .243 in the current Rifle Magazine. He was below 1MOA for just about every load he tried. Lots of Varget used.

Consider it yours. PM me a mailing address.

I shoot 243. Tons of case capacity to launch 115 tubbs to super solid velocity.

I am leaning towards the cartridges that use a small rifle primer. 6mm Dasher or 6mm BR(A) at this point.

Good idea!
