7mm RUM or 300 RUM

Ok, I have narrowed my choice down to the 7mm RUM and the 300 RUM. I am leaning towards the 7 RUM, I have always been a fan of the 7mm's. I know you shoot as heavy of bullets, but was wondering if with better ballistic coeiffent, if it is still the better choice. Do you think the 7RUM is a dying cartridge and the 300RUM is better. Any help on this would be greatly apppreciated, just getting into long range hunting.

Re: 7mm RUM or 300 RUM

I just had a 7mm Ultramag built. 29 inch light palma Benchmark barrel, I have 50 BMG and Retumbo loaded with 180 Bergers. Haven't shot it yet as I am spending my extra time calling cougars.
I am also having a 300 Ultramag built. Just waiting for the barrel. Benchmark 29 inch light palma. Plan on shooting the 210 Bergers. So it will be at least a month for any comparision.

Re: 7mm RUM or 300 RUM

Hands down between the two the 300 is the superior round.

Any 7mm with a case bigger than the 7mm STW is a waste of powder and will eat barrels up pretty quickly.

There's nothing in N. America you cannot kill with confidence with the 7mm STW or 300 rum or for that matter the 300wm. I own all three, two of each actually! .

Re: 7mm RUM or 300 RUM

I agree that once you start getting extremely overbore, your loss of efficiency goes up exponentially. I think the 300 would serve you better. With the coming of the Berger 195 in 7mm, that may change the picture a little with a good slow powder.

If I was considering a 7 RUM, I would probably push the shoulder down to 40* and lengthen the neck to mitigate throat erosion. It is well know for eating barrels quick. A heavier bullet and slower powder would slow that process a little as well.

I've had both; the 300 rum will last longer, but the 7rum is a monster for offhand shots at moving critters, especially in the badlands. I've currently got a 7mmstw and a 300 rum, but may build another 7rum in the next year or two if finances allow.
You have to pick your poison here, as the 7rum may only last 600-800 shots if full speed, but the 7stw will be within 100 fps topped out and go 1200-1500 rounds accurately. The 300 rum will often get over 1000 rounds with ease, especially if you don't let it heat up at all.

Where in ND are you???

Yeah, what he said ! The 300 RUM is an awesome cartridge. The 7 rum is too much of a good thing. The STW will out shoot it, and out last it as well. As a matter of fact, the STW is making a comeback, and the 7 RUM is fading. IMHO.
