Hi guys,

I have bought a cheap pair of Winchester 670's in 243. Now its time to re-barrel and re-stock them. I was thinkig of either 243, 260 or 7-08 as it fills the gap between the 22-250 & the 308. The otjher advantage of those calibres is i can use a cdi BDM and 10 round AICS mags.

Any other ideas?

It will be easier to get 243 ammo than 260 ammo, at least it is in the US. Don't know how plentiful ammo is in Australia. If you reload, then I'd get the 260. Still, you can't go wrong with any of those calibers.

I choose 243.

Re: What calibre to fill the hole between 22-250 & 308

the 260 is a great little round I would suggest you at least try it out.
 
Re: What calibre to fill the hole between 22-250 & 308

either a .243 or the 7mm-08. both are great calibers
 
Re: What calibre to fill the hole between 22-250 & 308

Probably going to get nailed for this one but I would choose a .25-06. Your .308 will cover heavy game, .22-250 light, and a .25-06 would round out your options.

I have one and it is scary accurate. Took a running shot at a hog last year with it and made a near perfect shot at 418 yards.

Mine I use for varmint (would extend your range beyond your .22-250) and deer.

.257 is another good choice as is .270 and .280
 
Re: What calibre to fill the hole between 22-250 & 308

.243 with some DTACs.
 
Re: What calibre to fill the hole between 22-250 & 308

I have a .243 and I really like it, but they are barrel burners. It all depends on how much you are going to shoot it and what it is you are shooting.
Are you looking for something to use primarily for long range varmint and predator hunting and some medium sized game?
That is the realm of the .243. The .260 would be a fine choice here, especially loaded with 123 grain match bullets for the long range varmints/predators.
Do you want a rifle for occasional varmint/predator, mostly medium sized game and occasionally large game? 7mm-08 for that and the .260 can be used in this role with carefull bullet selection.
The 6.5 Creedmore and 6.5x47 are also good options.

So, how's that? I covered very much and said little to help you out. One of the 6.5's will probably fill that niche best (creedmore, x47 or .260)
 
Re: What calibre to fill the hole between 22-250 & 308

fast twist barrel for the 243 and the 260 would be nice. 7-08 would be my last choice of those three.
 
Re: What calibre to fill the hole between 22-250 & 308

Since you probably have a regular twist .22-250, you can't really get any precision out of anything beyond 55gr. Not a bad thing, but no high BC or longrange shooting for you....

Want something between .308 and .22-250?
Why??? Just figure that a dingo hit with a 100-140gr bullet will die better than if hit with a .30cal 150/5 or 168??? Not really, mate!

A 6mm might be your optimum choice for "in-between", and why not go 6mm/22-250; and make it Ackley Improved???

Do that though, and you'll be wondering why you've got that .22-250 hanging around... So, don't do 6mm.

In a 6.5mm, which has better bullet selection than the .25cal, you might consider the 6.5-06. As its all about Bullets, this ctg wins handsdown over the .270win. If you are a real experimenter and gadgeteer, there's always the 6.5x55 Ackley Improved. That one is a bit more "interesting" and versatile than the 06 variant, but good luck finding a die set. Yet the long neck and extra seating potential the 6.5x55 offers makes it the real sleeper in this caliber category. Too bad Sierra no longer makes the 155gr matchking
 
Re: What calibre to fill the hole between 22-250 & 308

first off , what gap are you trying to bridge??

Small game/varmints , targets , big game?

what bullets are you shooting out of your other two?

Q. What calibre to fill the hole between 22-250 & 308?

A. Simple math: .308 + .224 = .532
.532 ÷ 2 = .266
.264 rounded to nearest caliber.

Recshootr -

I agree that the .25-06 is a great round, but I don't know that he can go that route in this instance. His action is a .243 - isn't that based off of a short action? the .25-06 is a long action based round. Admittedly I don't know enough about some of the other calibres proposed to comment on them.

I can also say, in response to another post above, the first thing I did after picking up my .25-06, was dump my .22-250. It's a rockin round, but I just didn't shoot it enough anymore. I can load 'down' the .25-06 and run lighter grain varmint bullets, or pump it up to 117 gr bullets for medium game. Some duplication there, at least for my intents and purposes.

The.260REM is an underrated cartridge, worth a serious look.
 
Re: What calibre to fill the hole between 22-250 & 308

Thanks for all of your posts. I should clarfy, a mate has a farm and is getting a permit to kull some roos (yes they are a protected animal but they get into plague proportions). Its a mid sized farm and i can shoot out to about 500-600m without a problem. So i am trying to shoot an animal the size of a 5-6 ft person.

The choices i have are:
SPS Varmint 22-250, standard twist, it was on special i had to
700 VS 223 18" barrel, jag conversion is on the way
M70 fetherweight 270 which is great up to 250m.
700 LTR 308 just been dura coated and not shot yet

I have been reading a lot about BC, retained energy/velocity and the 6.5 & 7 have a good 10-20% more hit than the 308 past 400-500m. I know these are paper figures and a well palced shot will do it but we are human and we can make errors and i would prefer to have more hit.

My dad has had his 670 Winchester in 243 since 1972 and for the last 20 years my brother has been shooting it. I would have fired 5-10,000 rounds and it still shoots moa at 100m. The 670 is a long action with a small box. I can get the dbm from cdi to take both short and long action calibres as long as they have a .473 bolt face and are no longer than a 7mm RM / 300 WM.

i am happy to load wierd ammo. I have been loading 38-45 and 9x25 in pistol calibres so i dont mind the challenge.

You grabbed those 2 winnys from used guns this week, had a look at them mate if I didn't already have the XCR TACTICAL as a switch barrel would have snapped them up. Mate 6.5x47lap or .260rem, you will love it! Both great cals that will smash roos out to 600m in the right hands and will still take game like Fallow, goats and pigs. While .7-08 is a great round I think its a bit close to the .308. The only down side to the 6.5x47lap is the brass or lack of it, only lapua brass in OZ (fantastic brass, I use it)but you can form it from .243 if you have the ability to.

Sure did. I think i will make the best 243 out of the 2 rifles and then rebarrel & restock the other in 260 or 6.7x47. It will depend on how hard/expensive the brass is to get for each round.

Now its a barrel length question. I like them short but i will need 26" to make these round work. MAB is open tomorrow so i will talk to them about the barrels and what reamers they have.

Thanks for all your posts, must appreciated.

I have made my decision and ordered the barrel, stock, DBM, dies & brass.

Would really depend on if you are reloading or buying off the shelf ammo. Reloading I would go with the .260...off the shelf, I would go 270 Win.

I'm hoping he figured this out 12+ years ago, but good reply.
