Appreciate that. I have a spare Rem 700 LA. It's ready to go. I skeletonized the bolt handle and fluted the bolt. Thinking about skeletonizing the action also to some degree. Just need to find a Smith to do that. Maybe drop a couple more ounces. I think in the end, after mag in loaded it'll come in closer to 9 lbs. Hoping for mid 8s. We'll see.My 284 came in at 7-6 with rings no scope. Not a proof barrel. 23” with brake fluted #4. LA BAT. Built for me by Alex Wheeler. If I removed the brake I would be close to 7 with rings. Added 3-25x44.
To save weight you could consider a titanium action or maybe a medium length like a Lone Peak.
Good luck on your build. Post your results when done.
