I know I'm about to sound old-school as he'll, but go with a fast twist.243. Its the cartridge that put the 6mm Rem out to pasture to start with. You can always find them in any sporting goods store if something happens to your reloads. Just saying.

I have had several 6mm-284s. Barrel life is short but if you want a fast it is a great choice.

Using 6.5-284 Lapua brass necked down and neck turned. While it requires a few extra tools and a bit more effort it is not difficult. I use Redding body die and bushing die after brass is prepped.

The heavy rig:
Over a decade ago, I built a 6mm-284 on a #7 28" 5R Bartlein 1 in 7.5 twist. Shot 107 Sierras and when they came out the 105 Berger hybrid. Only shot 2-3 shots in a row then let barrel cool. Was as careful with this barrel as I could be and it lasted right around 1100 rounds. some data:

The 28" barrel and 105 Bergers. Seating depth is set so loaded ammo would fit and feed from a a Wyatt's mag box in a SA Remington. Jump to lands .065":

58 gr of Retumbo was most accurate with velocity of 3307 fps

RL-33 shows on the scene:
Using same seating depth and other components I worked up some loads.
62.5 gr 3376
63 gr 3414
63.5 gr 3453
64 gr 3484 most accurate load requires a drop tube to get the powder to fit
64.5 gr some pressure signs
Should anyone try RL-33 in their rifle be sure start low and work up slowly. Your results may vary.

I used the 64 gr load with RL-33 to shoot a coues wt at 525 yds using the 105 hybrid berger. That buck wasn't huge and the bullet killed just fine.

The retired barrel sat around until one day I decided to cut off 3 1/2" from chamber end and rechamber it myself on my lathe. The rechambered barrel once again shoots! I am getting just a bit over 3400 fps with the shorter barrel using 62.5 gr of RL-33. It is now setup as a single shot with bullet seated .010" from lands. I don't think the new chamber will last very long but it is only used to wack long range varmints and occasional steel.

========================

I also have chambered two 24" Rem 243 takeoff barrels. Both shot the loads below. The twist rate is too slow for anything heavier than a 95 gr bullet.

55 gr nbt @ 4100 with 51.5 gr varget this load vaporizes the small rock rats and kills coyotes and jackrabbits with authority
95 gr classic hunter and 51 gr of RL-17 Fed 210m 3465 fps Friend used the rifle to kill a book coues wt a few years ago.
==========
Fed 210 primers used in all loads

Factory takeoffs are inexpensive and it is easy to rechamber. Only issue besides twist is that they tend to foul more than a custom barrel.

Will I continue to have a 6mm-284? Yes. Will it be a regular shooter No.

I use my 6 BR far more often for shooting at steel, rock rats and other varmints. FYI with a 30" barrel the puny 6 BR will get 3900 with a 55 gr ballistic tip using 35.5 gr of IMR 8208 XBR. Gets 2800+ with 105-107 gr bullets.

IMO if you want to shoot often the 6mm-284 is not the chambering to use, barrel life is too short.

Hope this helps
I dont really have much is anything to add except the 6 creed would be very easy in most everything. Shoot even factory loads are there for ya.

But mostly wanted to say what a FANTASTIC REPLY AZ. I enjoyed that read

i built 2 - 6mmx284 rifles both are are extremely accurate and dang fast too, i also own 3 - 6.5 Creedmoors and 1 - 6 BR bench rifle , if i was to build only one bench rifle it would be a 6 BR, barrel will last a long time and that little cartridge shoots well out too 1,000 yards accurately. but for a true hotrod give me a 6x284 with a 28 inch barrel , both of mine shoot 4,000 fps with 70 grain B.T. Good luck with your choice,Twolf

Been reading LRH posts for a couple of years but this just my first post so forgive me if I don’t get it right. My gunsmith is starting a re-build for me this week and I can build pretty much whatever I want. I am replacing the barrel and rebuilding my first rifle that I owned - a 244 REM 700 ADL SA custom that I had loads of fun LRH with killing ground hogs, varmits, deer and winning bets long before there were range finders. It’s completely shot out so time to re-barrel / rebuild. I love speed and plan to use the rifle for long range steel and varmit hunting. I was thinking of building a 6-284 but I don’t see very many people talking about the cartridge and wondering why. 6 Creed might be a good choice too and wondering what you guys think. Thanks
I thing a243 is better than 6mmcreed. I'd go with 6mm 284 if I wanted speed.

The only reason the 243 put the 6mm out to pasture wasn't performance but BAD marketing by Remington with wrong barrel twist. 6mm Rem. was a better performer by far all things being equal. JUST SAYING nothing wrong with the great little 243 Winny. And WALMART and the local gas station sell the 243.
Personally being a 6mm shooter since before "It was cool" any 6 is great but with a short action as has been mentioned pretty hard to beat the 6 XC or 6 CM. With today's great bullets these fit the bill.

You have already been give a bunch of great ideas but I’ll still put my $0.02 in. I have a bolt action 6mm creedmoor and AR10 6mm creedmoor. It is a great cartridge but you have many other great options. You can push 55 gr bullets over 4000 FPS for short/moderate range varmints. I’m getting over 3000 FPS with Berger 115 for long range work. There is abundant quality brass and factory ammunition available for the creedmoor. Hornady provides decent factory ammunition if you lack desire, time or materials to reload. Even in the last 18 months with all the shortages I’ve been able to buy Peterson and Lapua 6mm creedmoor brass for less than $1/brass.

A fast twist 243 win or possibly AI would be just as good or possibly better than the creedmoor. 243 win is one of the easiest cartridges to find factory ammunition for. I would argue that the last 3 years it has been easier to find lapua and other quality brass for the creedmoor.

If you want more speed and are willing to put the time and $$ to find, prepare and buy materials for the 284/6mm that is another great option. You may also want to look at the 243 WSSM.

What I was afraid of. I really want the short action. If I build long Ima go with a long caliber. May just do the 25-284 and stay around the 110 hammer length or less.
I think you will probably be ok with the 117 gr absolutes in a short action. Not positive but think so. I have a 1-8 twist the two main bullets will be the 90 and 117 gr absolutes I want all the velocity I can get out of this little rifle . So far looks like I will finish around 3650 too 3750 fps on the 90 absolute, if I need a heavier bullet I'll use my prc or something bigger velocity too me is where the 25 cal shines especially with the 90 gr absolute I will post my loading results when finished

What powders you plan on testing? I was kinda leaning towards the h4831 range maybe even a little slower but not sure.

Ive got a Speer #9 reloading manual that has 25-284 loading data the list 58 grs max Imr4831 at3623 fps and Imr 4350 at 55 grs max 3509 fps with a 87 gr spitzer I'm trying h4350 but using this manual as a reference Don't mind sharing the data if interested

Simple, just go look in the mirror, if you have a man bun then go with the Creed. If not, go with the 6-284.
Go with the 6 creed, does everything well except very large game. 3188fps in a 26" proof, 105 berger. I absolutely love mine on hogs and I @ 68 I have no man bun. No plans to get one despite the creed haters.

10-4. No worries. If you get a chance, check out Hodgdon's Reloading Data website. They have data on the 25-284. You might see something there you like as well.
Just for info I also load for the 284 and 6.5 284 last night I took a look at my compitition seater I use for my 284 win and tried it out on the 25 -284 couldnt believe it . 00 run out no where on that compitition die does it say 284 so I guess it will work with any 284 parent case that is a redding die
