This is a long time debate and there is no one correct answer but I will give you
my reasoning for choosing a 300 RUM.

First I have had several 300Win Mags and loved them and used them for long range match

When the 300RUM came out I found out that they were just as accurate, and could be used
at the same velocities with the same bullets and have longer brass life than the 300WM.(More
slow burning powder with less pressure and felt recoil) "OR" loaded up and extending the
effective range by 2 or 300 yrds.

So my logic was why own 2 rifles when you could have one do the work of two.

You can load a 300RUM down to 300WM energy and velocitys but you can't load a 300 WM up
to perform like a 300 RUM.

Barrel life depends on how hot your loads are .Obviously a 300 RUM loaded 300ft/sec faster
than a 300WM will erode the barrel faster . The downside to speed is throat erosion, the
upside is trajectory.

If you take a 30/378 up to its potential it will erode faster than a 300 RUM.

So if I want to hunt deer size game I can load down with light bullets and still get good
performance or load heavy bullets hot for elk size game,

If you have a 300WM you don't have to sell it and buy a 300RUM, But if you are going to
buy a new rifle in 30 cal ,of the two I would recomend the RUM.

Just my 2 cents

Some answers might be found in asking how much you shoot. If you are going to use it for targets, paper and lot of hunting like we do, and put 100's of rounds a year through it. Well, That is why we went with the Win. I searched till I rounded up a supply of Lapua and RWS brass and I am a happy camper. I hate it when I go through the prep of cheap brass just to see it go away in only a few firings. Plus I find Lapua and RWS brass need less prep before loading. But as stated you can down load the Rum to Win velocities and the barrel and and Rem brass will last longer. Still doubt it would last as long as Lapua brass in a Win.

That is why I have both. I bought the 300winmag first and 4 years later I came accross a deal I couldnt pass up on a 300ulta. I personaly like the 300wm the best its in a Remington sendero the 300ultra is a Rmington bdl
