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.
When the time comes to rebarrel my .300 RUM I, too, plan to install a muzzle brake. I have hunted Africa a number of times and have shot some very large calibers - and I can tell you from personal experience that a .600 Overkill with a muzzle brake is much tamer and even pleasant to shoot, whereas without the brake, it has a tendancy to twist and torque your torso and pound your shoulder in a violent attempt to rip your shoulder off your body. But the thrill of shooting a charging 2000 lb Cape Buffalo at 40 feet with this beast is beyond words and must be experienced first hand. I think I like the .300 RUM partly because of its awesome performance on big game at extended ranges, but also because of the recoil. I know it sounds wierd - kind of like a boxer saying he likes getting hit with a hard right cross - but I have always had a real love for shooting, big, bad guns, and my .300 RUM certainly qualifies.

Maybe I'm a little spoiled

If you have some IMR 4350 try 80 grains over an E-tip or other 180gr.
Also try 77Gr of IMR 4350 over a 210 Berger.
Those loads were by far the most accurate in my barrels...Not fast, or temperature stable, but insanely accurate.

Are you shooting a factory barrel?

I recently sold my Sendero and will be recieving my "new" 300 RUM project with Broughton 5C barrel. I expect it to be a good shooter with max loads. My plans are to try 230 Hybrids with RL33 and 200 CEB's with Retumbo. Don't plan on shooting the E-Tips anymore unless I decide to work up a short to mid range load.

I don't like using less than 90% loads which would be around 90 gr in the RUM, especially for hunting rounds.

My load for the 210 Bergers was 93 gr of Retumbo which gave me a little more velocity than H1000 for what I considered a max working load. I'm a full throttle kinda guy and that's why I have a RUM.

I hoping for about 3100-3200 fps with the 230 Hybribs pushed by RL33 down a nitrided 27" 5C barrel. Time will tell

Re: 300 RUM barrel life

Nice!
Expect a new (smaller) world of accuracy.

I shot some high 0.1 and very low 0.2 with mild loads of IMR4350.

Re: 300 RUM barrel life

That is impressive for sure. Accuracy is very important and so is velocity for LR hunting. For the hunting aspect, 1's and 2's is great but 3's and 4's is probably acceptable if it comes with higher velocities which extends range. I think also if I was looking for the smallest groups I would probably shoot bullets in the 180-190 range from the 300 RUM. Probably Bergers or SMK's. My goal is the highest velocities with the heaviest bullets and acceptable accuracy. 3's would be really nice.
