ok Ill bite on this one 
The 6-284 is already a weeee bit overbore. My question would be, "how long of a shot are you wanting to take on yotes?"
The 6-284 has all the boiler room you could possibly want and yet drive varmint bullets in excess of 3400+fps. If the guns sole purpose is for coyotes and long range. I would break it down do the follolwing;
A) what bullet works and at long range
B)after selection of bullet, this will impact or decide the barrel twist and length.
Basically if you want to hot rod the light varmint bullets in 3600-3700+ fps than a 1-10 or 1-9 twist is where you want to be, BUT you will lose downrange performance/ energy (wind drift especially) at the longer ranges. Heck the 95vld Berger will reach 3400fps !!
or
Go with a 1-8 twist and utilitze the 105vld berger hunting bullets (3200 fps) or numerous 100+grain bullets thats out there. You may even get by with the 115's. These bullets are more in the line of long range hunting especially for yotes.
I personally did the same as you 14 years ago and went with the Tac.20 and bag yotes at ranges from 0-400yds and pitty the animal if he shows up in between me and 300yds. No brainer just hold still and squeeze.
You may want to look at the 6CM, there is alot of info here on the site. One big positive about it over the 6-284 is that it digest the H1000 which in theroy SHOULD make ur barrel last longer, but that is still to be determined at least by me. I currently have chambered two and they shoot fantastic with 8 twist barrels and shoot 105's thru 115's very well. 115's at 3050fps and 108's at 3150. This from a .243 parent case.

If I can see them, and get off a shot safely, I will shoot at them. I guess I`m looking for a hot rod that shoots the highest BC bullets I can get. You cannot always get a real accurate range went you get to 600 yrds oe more, so I want the flattest shooting round I can get at 600 yrd. plus. I`ll start with the 107 gr. Sierra bullets because on the terminal preformance of the 80 gr. 22 cal. SMK`s on coyote when pushed over 3000 fps., and hope they do as well.
Never played with the combo myself since its all in the calling & getting them under 150 yards to shoot.
Not just shooting at them if you see them as you said.
I have no problem hitting what I shoot at to 700 yds with my little 6x45 with a 65g vmax @ 3153 fps.
I only dropped 189 coyotes last year out here so I have some insight on coyotes & shooting them from 60yds to 850 yds.
IMO it seems to me like you need more long range shooting time and getting your dial ups correct instead of an overbored hotrod gun. Yea I know, that was no help.

Howdy !
I'm wondering whether you might not be able to increase your calibre choice, a bit ?
If you were to go w/ a 6.5mm - 7mm ( wildcat ? ), you would not run-into the " over-bore " wall,
quite so quickly as you do w/ a 6mm wildcat.
The 6.5s & 7mm include some of the most "aero" bullet choices there are.
This inlcudes LR-capable bullets of appropriate design & construction for use on varmint and prredators
I don't think you'd want to work w/ a .30 -378Weatherby Mag, shooting 110gr HPs.
IMHO.

Catfish, I DO NOT have a 6-300 WSM but I would think if you worked up a load with Ramshot Magnum or Retumbo then the advantage should be apparent. I believe there is a guy discussing his new 6mm WSM over at Longrangehunting.com now. I built a 6.5 STW a few years back against all forum wisdom and the Handloading challenge alone made it worth in, but what a performer! Not easy to load for at times tho.

I'll go with learning dial ups and windage.
Reasoning for the choice of this round. It is strickly for varments and I want to shoot bullets with little chance of a rickochet. I want the highest BC bullet I can get for wind drift and the flattest shooting I can get for when you can`t get a real good range on the target. I have yet to kill my first coyote over a call and get most of them watching corn field when they are being shelled and a few just sniping them where the shots can get real long, at least for Ohio.
Nomad47 said:Catfish, I could be wrong (I was wrong once in 1998)but I don't think the flattest shooting bullet and the bullet with the least wind drift can ever be the same bullet.
So I think you first must choose flat shooting or less wind drift, then you can choose a barrel twist rate.
Add 2012 to your list!!
When distances get WAAAAYYYY out there, that flatest shooting bullet will always have the best wind bucking ability. You just gotta look WAAAYYYY out there. The OP was talking about long range yote hunting. At long range the "light weight, lightning fast, flat as a laser speed kings" at short range drop off the face of the earth when you get to 4 digit distances. As does their wind bucking ability.
I think one of the VLD type LR bullets in 115 grain would be just the ticket....best of both worlds.
My opinion is that no matter how flat the bullet is, when you get way out there you still need to dial up or use your reticle for hold over for all bullets. Not many guys dial for wind. Usually "Kentucky windage" .... and a bullet that does the best job at bucking the wind is king in LR hunting. That is always the high BC bullet.
Again, just my .02.

If it were me, and was stuck on using a 6mm, I would go for the wildcat, a long barrel, and try to get the 87gr vmax's to shoot. I shot them out of a 243ai and they were rediculous on chucks and foxes out to 800 easy. They have a pretty decent bc (.400) and you can push them fast! If your going that overbore I wouldnt consider anything less than a 28" tube.
VMax, it`s like 4X said, BC rules when you get out there. The Sierra 107 MK has a .527 BC above 2,500 fps and I`m wanting that velocity for a long way out. As 4X also said I use a drop chart and dial in elevation and use mil dots for wind drift and led on running targets. The high BC bullets gives you just a little wider window on both elevation and wind drift when you get way out there.
What happened to the 600 yard shots you spoke of earlier, Catfish? Those 107s are definitely not the flattest shooting bullets at 600 yards.
I'm a fan of high BC bullets. I have 3 6mm barrels, all 8 twist, all shooting 105 grain bullets and capable of 1000 yard shots on varmints. Two of the three barrels have killed groundhogs beyond 1000 yards. But I know they are not the flattest shooting bullets at 600 yards.
BTW, the third barrel is a new 6-284 and still in load development. It's definitely my "hotrod".

"600 yards PLUS" . 600 yards is his STARTING point...not the end.
6-284....I soooo want one. Just hate the thought of frying a bbl so quickly. As much as I like to tinker, I would have just found "the load" and it would be time to buy a new tube. ;D
4X, your right. Nearther of the 6-284`s I have now will shoot heavy bullets, but the group I spoke of was with an 80 gr SMK through a 224 TTH. I bought 96 lbs. of powder that is to slow for the 6-284, I can fill the case and not get the velocity of the faster powders. Solution, get a larger case. ;D
My 6-284 is only a 26" barrel, but I have seen 3334 MV with a 105 grain bullet and no pressure signs. It's a used Shilen that had 40 rounds thru when I bought it. I've got 50 rounds down it and I'm still tinkering. I hope to get another 800 fun rounds down the pipe. But before it is worn out, I will have a 28" Criterion barrel ready to screw on the Savage action.
Yeah, its a real barrel burner, but for $300 and change I can have a new chambered barrel. Brass & dies already bought, so the barrel is the only expense. Like I said, it's my "hotrod".

I am really curious which powder you bought 96 pounds of but is too slow? It's like a fun mystery....
I bought 50 pounds of W872 for my 6.5 STW, and while it is not too slow it certainly is temp sensitive. Have to rethink my whole load development strategy.
My 6-284 likes H1000 the best so far but think Retumbo would be just about ideal.
