I haven't burned out a 300 RUM barrel yet.
Neither have I, but I already have plans to have this rifle rebarrelled in .300 RUM. I really do like the caliber and the recoil doesn't bother me...yet...even though I am 63.

You must have loss of feeling in your shoulder or something. I shoot mine (unbraked) off the bench and wake up with a purple shoulder the next day.

I'm planning on rebarrelling my 300 RUM into a 300 Norma mag (not really a whole lot less powder capacity) after the barrel goes, as much to be able to seat long bullets out and mag feed as anything else.

As for this being a mild load, I could and have loaded hotter, but so far this has been the most accurate load - either factory or custom hand loaded - that I have found for my .300 RUM. Besides, I'd rather have a .5 MOA 180 gr bullet at 3250 fps that I can hit with at extreme ranges - I shot a 11x13 point Muley here in Colorado at 930 yards and dropped him in his tracks with this load - than 180 gr bullet at 3450 fps that gives me 1.5 MOA and a likely miss one the same shot. It doesn't matter how fast you can push it if you can't hit what you are shooting at.

Besides, I would rather see how many accurate rounds I can get out of this rifle than to see how quickly I can burn out the barrel.

One thing I have found from reloading the RUM is that it likes the heavier bullets. The 180 grainers do pretty good, but the round really doesn't start to reach its potential until you get to the 190 to 220 gr bullets with the higher ballistic coefficients. I also found that very slow burning powders that give me a 90% fill ratio for the .300 RUM case give me greater accuracy and less fouling and throat damage.

You can burn up a .300 RUM barrel in less than 200 rounds if you don't give the barrel time to cool down - after every 3 rd round at the most. I like to see just how long I can shoot this rifle before I have to have it rebarrelled. I'll be hunting elk and mule deer with it again this year. I routinely practice with the .300 RUM by shooting water-filled plastic milk jugs at ranges out to 1000 yards, and if a muley or an elk walks out at anything short of 1000 yards, it just committed sucide.

I do like the Nosler custom loads, and I have enough of them to get me through this next hunting season, but I can't afford to pay $86 per box of 20 without losing sleep over sending a few practice rounds downrange.

I have a box of Berger 220 gr bullets ready to go to the press just as soon as I can find some more primers and powder. I can't wait to see how well those do.
You are dead right about the 300Rum shooting with amazing accuracy at lower speeds. Especially with 180 grain bullets. As you suggest the Rum is better with the heavy weights and I shot it accordingly. IMHO the only reason to own a 300Rum these days is the 230 Berger OTM. The big Berger will deliver what you what you were looking for from the 300Rum and barrel life should increase slightly over my 200 grain loads.

After a couple of barrels I retired the 300Rum and decided to stick with the 300Win. Not hacking the 300Rum, but the 300Win is just so much easier to please. Be advised that unless you are running the 230 in the Rum the Winchester so loaded will catch you and run you over at about a thousand yards.
Despite chest beating and 2500 round expectations (from some) I have found barrel life is not great with the 300Win either. By 1200-1400 rounds I am giving the barrel the evil eye and the hair splitting accuracy is leaving if not gone.....By 1500 rounds Elvis has left the building. Those willing to relax accuracy expectations can expect a significant increase in barrel life expectancy and my light hunting rifles go more than 1500 rounds.

Most guys grab my "shot out rifles" and are delighted with the 1/2-5/8"ish hundred yard groups they get....The problem is I know how well the rifle shot just a few hundred rounds ago so I am ruthless where it comes to barrels. If it doesn't absolutely rip...its coming off....I don't care what the counter says.

Your mileage is up to you.

Re: 300 RUM barrel life

My Sendero 300 RUM was easy to please and it shot 180 E-Tips in the .4 range @ 3400 fps. It shot the 200 AB's and 210 Bergers about .5 It was fine with max loads.

No loss of feeling and I also do not have a muzzle brake on my rifle. Compared to the recoil of a .50 BMG the .300 RUM is a pussy cat. My last range session was testing bench loads - 10 rounds each of 4 new loads - not the least bit sore the next morning. Just make sure you have a good recoil pad and hold the rifle tightly to your shoulder - I mean put some effort into pulling it into your shoulder. I see a lot of guys who shoot heavy calibers who are afraid of the recoil. The biggest mistake they make is they think the lighter they hold the rifle the less it kicks. Hey, if an old fart like me can handle the recoil of a .300 RUM, then surely you youngsters should be able to. But then, I'm an old Marine and I just like big guns. Try shooting a .600 Overkill sometime...a 900 grain projectile at .270 Win velocities! Now that one will ring your bell!

I agree with you 100% on how to hold and shoot the RUM. You need to hold it in firm and tight in the pocket of the shoulder... and I roll with the recoil as much as possible without fighting it. On occasion I have been a little sloppy with a loose hold and nothing will get your attention like that. However, I usually use a slip on recoil pad which helps a lot. If I'm just shooting with a T shirt or over shirt, I am probably dome after maybe 10 rounds. But with a good jacket and/or slip on recoil pad, I can shoot it all day.

That said, my next 300 RUM will have a brake to make it more pleasant and help me spot my long shots.

Call me a wimp Even my diminutive 6mm's wear a brake. For what I do & where I do it, there is absolutely no reason to not have a brake.

Maybe I'm a little spoiled
