Burned up my barrel in a fast twist 22/250. Is shooting the long heavy bullets harder on bbls then shooting slower twist with lighter faster bullets.

Howdy !
IMHO - bullet wt choice can and often does drive one to use of a different powder than is used w/
comparatively lighter bullets in the same chambering and barrel length. That might result in a powder
being selected for the "heavier" bullets that burns hotter than does the powder used to propel the lighter bullets. That being the case, barrel life might be adversely impacted.

Standard load was 37.5grs of Re#19 behind 77gr Sierra TMK ,last time shoot these loads bullet were keyholing at 25 yds.
Yes, heavier bullets are significantly harder on barrels than their lighter counterparts. That's based on burning out many hundreds of barrels, in a wide variety of chamberings and bore diameters.
Yes, but a 22-250 is a barrel burner as is.
Then when you shoot hard and fast strings it makes the situation worse.
I think the barrel steel has something to do with it too. I had one barrel in 6x47L go 2400 and the next go at 1500. If anything I was harder on the one that went 2400 because I did a lot of experimenting with it.
More like under 3 seconds.
I sure though that bbl went fast. Maybe next BBl will be a 9" and limit it to 69 gr bullets ?

You might consider downgrading the cartridge if you're getting a new barrel anyhow. A .22-250 isn't very efficient and you could so almost as well with something that uses a good bit less powder and treats the barrel a little better. I'm not an expert at this sort of .22, so someone could chime in with better advice. But maybe a .22 BR or something along those lines.
I burned mine out at approx 2,000 rounds by that I mean the rifle would not longer hold 1 moa. No big deal for a big game rifle but significant for a long range varmint rifle.
I sold mine and now use a 223 Rem for all most all my varmint hunting since my max range 99% of the time where I hunt is 250 yards and under. The 223 Rem has a long barrel life if you don't abuse it by shooting rapid fire strings in a hot barrel and if yhou clean regularly with an effective carbon and copper solvent.

Heavier bullets with a longer bearing surface require more engraving force from the lands and so the throat recedes faster. Other then that Usually slower powder have a lower burn temperature and are a little easier on the barrel but is offset by the length of the bullet.

Lighter boolits work great for me on varmints/prairie dogs. A 221 Fireball chosen for most of the work at present... 35gr Bergers and 18gr of 1680 should make for a long life... Hopefully, lt'll age quite a bit this time next week blasting Prairie dogs in NM.. If l do burn out the barrel throat, lts not the end of the world. l can get it rechambered to 222 or 223Rem... Sadly too many choices to ream out your 22-250.. Short action keeps you from reaming it out to a 220 JayBird.. 270Win necked down. Maybe set the barrel back a few threads.. Then again you could opt for a 1 in 12 twist and 55gr boolits. Couple our prairie dog guys from Canton Tx are in the ''500 club'' with this combo..
Yes it is the increased barrel time which causes the throat erosion. Barrels don't WEAR out from long bearing surfaces, the throats burn out from longer pressure/time curves of heavier bullets.

What is your round count on that barrel?
Yes . Long /heavy for cal are harder on barrels but in a 22/250 800-1200 is about the accuracy life of the 10-15 22-250 ive rebarreled in the last 8-10 yrs . Sure some spent money and time trying to regain there youth sorta say , but it was wasted time and money . For what the spent trying every product , cleaning , dies , bullets , powder , primers , etc , they could have installed a premium barrel and Been shooting itsybitsy ( tiny ) groups again .
