yanno I know one person in my area that shoots an ultra mag period, its a 300rum.... so either are rare. I too like to be different. BUT I want something that is going to perform.
reason I was thinking about not going with not going with the 7mmRUM... is I hear a lot of stuff about the smaller rounds not carrying enough ass to dispatch animals on out to 1000 yards.
There are couple of very simple rules of thumb when choosing cartridges.
First is.... the bigger the better.... when it comes to killing effectiveness. bigger diameter holes and bigger bullets with more mass on target will do more damage and kill better on average.
Next is.... the faster and farther you want the go the more powder you need to burn. The more powder you want to burn the bigger the case you need.
Third is... it all comes with a cost... bigger brass, bullets and more powder will cost a little more in $$$ and they will have more recoil. Recoil can be dealt with in a few ways and one popular way is with a brake. Brakes are very nice for diminishing recoil but also come with a cost. They make a very big noise, add a little to the length and weight of a rifle and can be an encumberance on a carry rig.
Beyond the basic rules of thumb there are other things to consider such as specific bullet availblity in ea cal. When selecting cartridges some overbore cartridges tend to go through barrels fairly quickly and rebarreling will cost $$$ and down time. If you several rifles and the budget, that's not a big deal.
You need to consider the rules and determine your priorities.
For a primary hunting rifle, I would put function ahead of cool. You might be able to have both.
I set *MY* priorities this way.... 30 cal min for primary hunting rifle which includes elk. RUM cartridge for 1K plus range. 30 cal max for recoil. This narrows it down to a 300 RUM for me. With a good rifle I can reach 1000 yds and I can handle the recoil without a brake which is what I want for a carry rifle. Those are *MY* priorites.
Hope that helps.
