300 win easily on account of economy. I've used 300win, 300wby, 300RUM, 30-378WBY and have enough time with them. Still have an 300win mag but truthfully I've no use for them. Having more common standard cartridges like 270win, 308win, and 30-06 is preferable. If I feel the need for mo' better I go to my 338win or 375 Ruger. There's nothing really wrong with the 300 class but if I'm pushing a larger case I want more bullet weight.
