Please educate me. Why 7MM Remington Magnum for the US squad on the upcoming F-Class World Championship.
Desert Fox said:7MM RSUM is a good choice although a 7WSM will be just as good. Must be the slightly long neck of the RSAUM.
Not sure about less recoil. I shoot the 180 Berger on my 7WSM with 30" Broughton and it sure hell I felt the recoil. My rifle weigh around 18 lbs. My barrel gets hot quick also, especially shooting in Southern California weather during spring and summer.Plus for less recoil and barrel heating I'm sure.

ScottMc said:Mystic, I started a thread a few weeks ago about reduced loads in the short mags. Is a short mag backed off to 2800 a lot harder on a barrel than a straight 284 at 2800? If so, why? I need practice more than anything, so I am looking for a round with decent ballistics that will last 2000+ while I learn the ropes out to 600 y. Lately I'm thinking about a 7mm-08 or straight .284 with 168 and 175 sierras.
A lot of good info here:

flatlander said:scott, running a straight 284 with 180s at 2800 will take less powder than running a reduced charge in a larger case to get the same velocity. Case volume is the reason - it still takes more powder to reach the same velocity (2800) in the larger case. For a more extreme example, look at a 6 Dasher compared to a 243 Win. The smaller case is just more efficient - ie - the Dasher takes less powder to get the same velocity with a given bullet weight than the much larger 243 case.
