As a lefty elk hunter I was reading this thread with interest. I own a few of the rifles mentioned so out of curiosity I weighed the ones I have used elk hunting. The Ruger #1A in 7mm Remington Magnum with a Burris Fullfield 3-9 x40 weights 9lb 3oz. This was a fun rifle to use when I was in my early 30's. Not any more. My Browning A-bolt II Stainless Stalker in 280 Remington has a Bushnell Elite 6500 2.5-15 x 42 scope in Talley steel rings and bases weights 8lb 12oz with the magazine. This was used for many years while wearing a Bushnell 3200 2-7 scope. I weighed 6oz less then. Easy to carry all day through the densest brush. A more than adequate cartridge for elk too. Finally I have been hunting for the last few years with a Tikka T3 Stainless synthetic in 338 Winchester Magnum. It has a Meopta 4-12 scope in Talley lightweight rings. It weighs 7lb 12oz after I replaced the Tikka hard rubber butt pad with a Pachmeyer. It is much nicer (but not pleasant) to shoot now. It is a handful from the bench but with good technique it shoots well. You do have to pay attention when you squeeze the trigger though. I could go lighter but I don't think I would ever do it with a 338. The 280 for sure, and the 7mm maybe. For the price you just can't beat the Tikka though.
