You already have a proven and capable gun and the experience to go with it. If I were you I'd stay with it and perhaps install an effective muzzle brake
(if it does not have one) to make the shooting experience more enjoyable. Please note that muzzle brakes
are loud and the proper ear and eye protection is required.
If your looking at being able to a do a 100 shot range session, I'd go with a .308 Win ... lots of bullets and factory ammo to choose from at a very reasonable rate and the barrel life is hard to beat. Either one of your brand choices will serve you well.
