Re: Curious about the 7mm RUM..

I am not an expert on the overbore issue, but I have ready a lot of posts on this forum that talk about super big cases and 30 caliber bores.

They have got to be way more overbore than the 7mm RUM.

As with all overbore catridges, using really slow burning powder and keeping the temperature down makes the throat/barrel last longer.

In my opinion, the 7mm RUM is the biggest and fastest little bullet thrower available in a factory rifle.

The heavier 7mm bullets are very long and have good sectional density and ballistic coefficents.

I can't come up with a use for a bullet heavier than 180 grains.

A premium 180 grain bullet out of a 7mm RUM will take out anything in NA even at considerable distances.

I am really surprised that I don't find more written about them for long range work. I have one and would like to read more about them.

I know the really big - 30+ caliber heavy bullets have the advantage way, way out there, but I have trouble finding places to shoot over 300 yards.

That's why I chose the 7mm RUM.

Re: Curious about the 7mm RUM..

My friend and I bought our RUMs at the same time. I have the 300, he has the 7. Mine is much more versitle with so many 30 caliber bullets on the market. Just look at these stats. For the max loads, if you are looking for speed, the 7RUM spits a 140 grain bullet out with 95grains of H1000 at 3160fps. The 300RUM will propell a 150 grain bullet 3520fps with 102grains of H1000. The only disadvantage is recoil.
