I think they are here to stay. People are in the Magnum frame of mind now. You could write Magnum on a pitch fork and it would sell. I think the 270 WSM will do well because it is a Magnum but the recoil is not bad. Remington will win the 7mm race and Winchester will win the others. I think the 223 and 243 SM's will do well. I am still watching for the 257 SM and I think Remington may bring that one out. I am a 25 fan I would like to see a super short action like the 223 and 243 SM's in 6.5 as well. The are 1/2 inch shorter that the other SM's. I think the only thing that would turn this tide would be a drying up of the toy money if the economy goes down the tubes. Right now people still have the money to expierment.
