As we get older weight does come into play on a above timberline elk hunt. I like to keep my rifles under 8.5lbs most of the areas I hunt here in Colorado are walk-in or horseback only so no vehicles mainly locals that hunt and to be trueful I never saw anyone pack a Sendro and I spent pretty close to 3wks hunting. We get back in 3/5miles. If your hunting close to a vehicle or horseback heavier rifle wouldn't be too bad so to me I think till you get into what type of hunting you may change the rifle you first settle on so I'd look at something with a good resale value or a platform for a custom rifle
. Any of the 30cal mags would take care of your hunting needs. I haven't use a 30 cal on antelope.
