What do you guys think would be the easiest cartridge to get to shoot under a half inch consistently and fit a 700 with a .378" bolt face and mag, currently a 223......assuming a Gaillard barrel in the Rem Varmint contour....trued up and chambered tight and straight..

6x45?..6x47?...plain old 222 , 223AI?......20Tactical...204 Ruger?...one of the .17's?...what would be your pick?
 
223 Rem. You can easily get under 1/2 min with the bullets today.

My last Savage was pretty decent at 1 mile :)

Just get a 8 or 7 twist, push some 80gr Bergers or amax and you have way too much fun at distances that will make a 378Wby nervous.

I've seen your 223 at a mile video..very impressive. This will be a 400 yard max gopher and paper rifle....it's wearing a 223 14" twist King tube right now.........shoots 50gr VMax's decently but I want tighter groups.
 
Rembo, with the Gaillard, you will get better groups right away. So would a Shilen :)

Accuracy has more to do with the quality of bullets, barrel and install then the chambering. We have so many excellent dies and powders to tune just about anything. Not alot of chamberings that cannot be made to shoot in the 2's and 3's if match bullets are offered.

I would go 223 since you want to reach out and splat something. Definitely go faster twist as the wind is your biggest foe at those distances. Pretty hard to dope to the MPH but if you can't, the lighter 22's will get blown off a PD.

The heavies are not explosive but decisive on impact.

I'm glad to see a question about accuracy for a change and not which cartridge is "fastest" or what Kaboominmagnum will give you the biggest "c*ck."

In a 223 bolt face Triple deuce Hands down. This was THE short range benchrest cartridge to beat before the PPC hit the scene. The old 6X47 based on the 222 case is also a needle banger
 
Something Exotic

From your choices the 223 looks good.
For something different, buy a new reamer. Take the 6.8 Rem SPC and neck it down with a 30 degree shoulder.
Look at all the options you'd have and your own personal caliber, ie (6-REMBO)
Bolt face would have to be opened a bit.
Take care Bill

Caught me too!

The Gaillard .222 I used to have was nothing short of amazing, but the .223 might be the better choice to reach out as Mystic suggests. I had a 1:7 twist, and the only bullets that it wouldn't shoot was the light SX's and Blitz's that tended to blow up before getting to the target. Everything from 52 gr MK's on up shot like a house on fire out of that barrel.

Consider making up a dummy round with the bullet of your choice seated in such a way that the bullet shank just ahead of the boat-tail is in neck and only the boat-tail extends into the shoulder of the case; then have your gunsmith cut the chamber to that length. The additional powder space will give you a little more oomph with heavy bullets.

Did I hear 6mbr?:D

Amen brother! But I'd just buy a new bolt from PT&G with the 308 boltface and then I'd have a switch-barrel-switch-bolt-switch-caliber gun, and no Sako extractor concerns. (And a 22BR a 6BR and a 30BR to boot!)
