Zeke-BE Report post Posted January 7, 2017 I didn't want to hijack Greyghost85 thread. But do we know many rounds each caliber can handle if loaded near top peak? Also does anybody have an idea how many loads can some one do with a light load ? What have you guys seen?? Share this post Link to post Share on other sites

300RUM Report post Posted January 7, 2017 There are a number of variables in barrel life. The capacity of the case in relation to bore Diameter, or How much hot gas is getting forced through what diameter hole. The choice of powder. The velocity of the bullet. The length of the bullet, or how much bullet surface is in contact with the barrel. How much the shooter lets the barrel cool between shots. The diameter of the barrel, or how much mass it has. The quality of the barrel steel. I have seen a 300 ultra barrel deteriorate in 1000 rds. I have a heavy barrel 308 with over 5000 rds that can still hold under 1/2 inch.

DesertBull Report post Posted January 7, 2017 I saw a chart on longrangehunting.com not too long ago regarding barrel life. Overbores like 7 mag, 264 mag, 300 RUM, etc 800-1500 rounds. On average. I think the best thing is to make sure you dont over heat the barrel. That is why i like to take at least two rifles or a pistol with me when i shoot so i am not tempted to shoot too many rounds too fast. Also over cleaning and/or incorrect cleaning is a factor in barrel life i think. 1 Share this post Link to post Share on other sites

Cleaning from the muzzle end can damage the muzzle and degrade accuracy. 1 Share this post Link to post Share on other sites
Guest oneshot Report post Posted January 7, 2017 I burned out a .223 in ablut 2k rounds. But I was young and abused it. I've shot around 4k rds from my Ar shorty(BushmasterAr-15 a1) and it still shoots just fine... New factory ammo(Remington) always, but my old DI Rupp would be giving me "correction" against a wall if he saw the condition of my Rifle... 100rds, 50yds, 20rd mags, off knee's, Nikon red-dot 0x, smiley face and center-mass blow through doing double-taps... (Thorax shot is the sighter shot) Share this post Link to post Share on other sites

lancetkenyon Report post Posted January 7, 2017 Lots of factors, most have been covered here. A few others as well. Case neck/shoulder design is another one. Bullet jacket material. Powder burn rate/capacity of case. Some barrels have severe throat erosion, which can be remedied by setting the barrel back and rechambering, making it as accurate as before. But heat checking or cracking up the lands will signal the end of barrel life. I would think your 6.5-.270 AI will be somewhere around 1000-1200. My .25-06AI has probably 500+ through it. I am too lazy to go look at my records. My 6.5 SLR already has way more than that in 2 years. Share this post Link to post Share on other sites
dse Report post Posted January 7, 2017 I have well over 2000 rds through my 270 Wsm pushing 130 Swift Scirocco's at 3475 fps on the factory REM. barrel. Still holding close to 1/2 moa, which is almost as good as it's ever shot. 1 Share this post Link to post Share on other sites
10Turkeys Report post Posted January 7, 2017 To completely shoot out a barrel would take a lot. I've gone through more than twenty and none of them were totally shot out, they just wouldn't group at the longer ranges that I shoot, 385 and 500 meters. Typically a 708 would get about 7000 rounds, a 308 would get about 8000, and a 260 or a 6.5x 47 lapua about 3500. A friend of mine who liked a 243 usually got about 1500. I'm told that more hunting rifles are damaged by improper cleaning than being shot out. Also I never rechambered a barrel, but the ones that I have talked to that did said that it was good for about another 800 rounds, for a hunting rifle that's a lot of life,but if your shooting some kind of competition it's not much if you were paying someone to do it for you. 3 Share this post Link to post Share on other sites

I am too lazy to go look at my records. My 6.5 SLR already has way more than that in 2 years. So probably another 100 on load development, another 50-100 double checking Moa drops and another 1--200 rounds on practice. That would put me already on a new rifle 400-500 rounds. Those numbers are probably high but if I practice with it about 40 shots a year it will last me another 10 years then. Share this post Link to post Share on other sites
300RUM Report post Posted January 8, 2017 I have had my .300 ultra for around 16 years. I installed the 4th barrel a couple of years ago. They are still useable when I remove them but at a certain level of accuracy loss I choose to replace them. I have a load worked up and the rifle is always ready to go hunting. Like you are suggesting I don't shoot it frequently. I have a .308 that is my "practice gun". It is easy on barrels, uses half the powder and I can scrounge brass for free. 1 Share this post Link to post Share on other sites
