Looking at building a short rifle for deer and likewise game shooting 120-140grain bullet. Trying to determine whether to go with the 7mm-08 Remington, 7WSM or 7RSAUM with either a Bartlein 2b or a new Bartlein carbon wrapped barrel finished at 20inches. Most likely will put a muzzle brake on it with how light it will be. Will a Defiance XM length action be better than one of their other two shorter actions? Then putting it in a Manners EH6 or EH1. Thoughts or experiences with something similar would be much appreciated.
