Twist rate is certainly something to think about. Having owned a Remington SPS varmint I would not own another one. It wasn't a bad rifle accuracy wise it just didn't do anything right. It wasn't a great target rifle because the twist rate was too slow. It wasn't a great hunting rifle because the barrel was too heavy. Don't let anyone tell you that a hunting rifle should have a heavy barrel (unless you are doing high volume varmint shooting like sitting in a gopher field). Heavy barrels belong on target rifles and not in the field. This comes from a 22 year old guy who spends his summers and winters climbing all that the Canadian Rockies have to offer. Heavy barrels are just a PITA in the field and unneccesary.
