Ummm.... yeah there is a big difference when it comes to barrel life.
22-250 at 3100fps with a 55gn bullet and 34.0gn of IMR4320 has given me between 6000 - 7000 rounds. Based on 3 consecutive barrels on the same action.
223 at 2700fps in a Tikka T-3 with 55gn bullet and 19.6gn of IMR 4198 has given me 12,000 rounds and still counting.
I think if you do the math.

Only 6000 eh? My god, threads like this remind me how much more shooting some people have done compared to me....Another member mentioned somewhere that he had "only" burned out 3 barrels...in a Swift! plus a bunch of others. Man my next project is gonna be a .22 Rimfire minigun fed by a garbage can sized mag, just so I can go to the grave saying I've "only "smoked 3 barrels....
Thanks for the info!
6000-7000rnds is how many years of shooting for an average gun nut?.... you would have to shoot 40rnds a week for 3yrs to hit those numbers.....It would take me about 14yrs to hit 7000rnds thats 500rnds a year which I'm sure is more then most nuts shoot.....
I think my point all along hasn't been that barrel life will be 100% identical its that barrel life just isn't enough of a factor to base the purchase of a firearm on......any one can save $400 for a match grade barrel over 14yrs......

Glad to hear i am not "average"....lol
I average around 8000 a year and hit a high of almost 20,000 five years ago.......(thats a combination of rifle and pistol though)
Have not burned out a barrel yet.......trade them off too fast for that......lol

I used to compete with a 22-250 Ackley. Launched the 80 Sierra at 3200 to 3400, depending on powder/load. 30" custom barrel.
I am guessing a stock 22-250 would be 3000 - 3200.
I burned up 3 barrels in 3 summers, before I gave up. Barrel life was in the order of only 1000 rounds. When the barrel started to give up, bullets would start to exlode about 50 yards down range.
order a barrel with a 4" straight shank so it can be set back 2" after 1000 rounds.
My 223 barrels give up after about 9000 rounds, shooting the same 80 gr Sierra bullets at 3000 fps with RL15. (30" barrels). Same make of barrel.
The nice thing about a Savage is that with a spare bolt head, you can change barrels and calibers easily.

exactly
I'm talking about rounds through a single rifle if I factor in all calibers I shoot a heck of a lot more then 500rnds a year....but shooing 3000rnds out of my .22lr doesn't burn out the barrel on my .22-250.....
I've only been shooting "competitively" for 2 years (I wouldn't count my first year as competitive) and I have burnt out a barrel, set it back and have gone through 2/3's of it's acceptable life already, barreled 2 other actions and I am getting close to the time to re-barrel or set both barrels back.
Now my "acceptable" barrel life will vary quite differently from someone shooting gophers, coyote's, etc....

WOW running hot loads like that no wonder you burned up your 250 barrels so fast to get the speeds you claim those loads are way over max......
how many grains of RL15 to get 3000fps out of the 80gr'ers in the .223?
srt4u2nv,
I'm guessing you have not shot a 22-250 in an eight twist barrel and certainly have not chronographed one. Ganderite has and so have I. When I say I can get 3300 fps with an eighty grain Sierra (from my 28 inch barrel), I say that because that's what the chronograph told me. This load is maximum in the Remington brass I am using. My barrel is chambered specifically for the long 75 and 80 grain bullets. Plainly, you are getting your figures from a careful perusal of your favourite loading manual. Now hear this; the 22-250 will certainly achieve well over 3200 fps with 80 grain bullets and perfectly reasonable loads. Barrel life will, in a word, suck. Nonetheless, a fast twist 22-250 is an impressively flat shooting outfit and relatively pleasant to shoot. Just don't get real attached to that barrel if you plan to shoot it much.
The long barrel life experienced by shootist 22-250 is what might be expected with such reduced loads. He is shooting his 22-250 at 222 velocity levels and it is reasonable to expect barrel life to be similar to a 222. Likewise his 223 is loaded to produce long barrel life and the performance level he wants. Truly, this is intelligent loading. If I was smart (a claim I have never made) I would use lighter loads for practice and extend the life of my barrels a bit. Regards, Bill.

Thanks for the info would you mind letting me know what powder and weight your using?....I shoot a 1-12twist 26" tube the max I can get 63gr'ers to fly is 3400fps before pressure signs show up......so sorry if I find it hard to believe you can get close to that speed with an 80gr bullet....Does a match barrel make that much of a difference?....

how many grains of RL15 to get 3000fps out of the 80gr'ers in the .223"
Not over max at all. Both calibers are chambered with very deep throats to accomodate the 80 gr bullet. In both the base of the bullet is just barely past the base of the neck.
The 22-250 was stoked with WW785, as I recall - a slow powder. It never did show any signs of pressure, but I backed off at 3400 fps because the Sierra 80's would start to blow up. the barrels are 1:8, so the bullets were spinning too fast for that long thin jacket.
The 223 has been shooting Sierra moly coated bullets. I don't know if that has an effect on barrel life or not. As for the powder charge, that varies by rifle.
Although all my 223 rifles have McLennan (hi quality) barrels and are all chambered with the same reamer (JGS-Wylde 223), not one of them uses the same best load for accuracy. They use N140, N140, RL15, a non-canister Wincheter ball and RP28 (a non-canister Bofors powder, one step faster than RL15).
I load for accuracy. The accuracy load runs between 2850 and 3000 with the Sierra 80. All are 30" barrels.
The moral of the story:
Each rifle is different.
My rifles are very different than yours.
The rifle tested in the loading manual is different than yours and mine - even if it is consecutavly numbered from yours.

One of the problems on this forum is that a reader tries to compare his 22-250 (or any other caliber) to someone else's rifle in the same caliber. Does not work that way.
As I said, each rifle is different, even when consecutivle numbered. Inside dimensions of barrels vary. I have seen 308Win barrels as big as .309 and as tight as .3065. And of course, some are much longer than others. I always try to mention that my barrels are long, and with a big dose of slow powder, can boost velocities.
There is a big difference in chambers. Remington uses a much deeper throat than most other rifle makers. A heavy bullet can be seated much farther out, greatly increasing case capacity. A handloader can move up two or three notches of slower powers.
When you talk about a 1:12 22-250, that tells me you have a rifle made to shoot 55 gr bullets. The throat is short.
I design my own chambers and have JGS make me my own reamers. The chamber is designed to allow my intended bullet (a Sierra 80 in this case) all the way out.
The only similarity betweem my rifle and yours is we both use 22-250 brass.
I don't know how fast it will shoot a Sierra 80, but at 3400 the bullets blow up.
A visit to a reamer mske's websit ewill give you an idea of chamber choices.

FWIW
I own and shoot a 22/250AI in a fast (1n8) 30" Gaillard barrel.
The 80grn load produces a velocity of 3300 to 3400 FPS depending on my choice of powders ,and if one seatched (googled) 22/250AI you would find articles of others that have done so as well.
Ganderite is correct.What I can safetly accomplish in my rifle maybe dagerous in yours.
The AI version of the 22/250 does have it's advantages
