Hello , I to favor .280s versitility. I have a rem.700 KS,but if u can spend a bit go to Lone Wolf Rifle Stocks site.I have 2 Summit models with cheek pieces. With 3.5-10x50s,rem700s,24-26"barrels they weigh 8.00lbs. or less complete.Excellent workmanship. Dskiper
My 280AI is built on a pre 64 M70 action with a 24"fwt pac-nor barrel and bedded in a rimrock (28oz.) stock, with a 3x9x40 leupy in talleys it's at 7 3/4 lbs. and carries/balances very nicely. I also have 2 mcm edge stocks, the one on my pre 64 M70 fwt '06 weighs 23oz. and is a great stock. If you hurry over to 24hourcampfire.com you can save some dough on the edge, just look for santa.
Wondering if the 22" barrel in the 280 ackley if your gaining what the benefit of the ack. Maybe a regular 280 would do as well. As far as weight i have the ultimate light weight gun. 25x284 from ultra lite arms. I bought it used from a friend though. It has 24" barrel, 30 mm 4.5-14 leupold 40 mm lens, uncle mikes sling with 4 loaded rounds, harris bipod, weight: 7 1/4 lb. I got it with dies, and brass for 1k.
