Late to the party but swapped my older Savage DIY 280 AI build for a Savage Ultralight in the same caliber. I like it just as well as my Tikka. The Tikka has a smoother action but the Savage is more accurate. Every single hand load I have tried is sub MOA and pretty quick and easy to find loads in the 0.5MOA range. To me the Tikka and Savage triggers are about equal, I am able to adjust the accutrigger a bit lighter, not enough difference to fuss about. I am waiting on a Nightforce SHV 3-10 for this set-up which should be right around 8lbs.
For a superlight build I am in process of putting together a Howa Mini Action set-up in 6mm ARC. This will be a deer/antelope packing gun good out to 400-500 yards max. Put it in a Stockys CF VG stock and the bare rifle/stock weighs in at 5lb 4oz. Two stage trigger is fine and breaks nice and clean at 2.5 lbs. I have a SWFA UL 2.5-10x32 on backorder. However thinking I may cancel that order and go with a Trijicon Accupoint 3-9x40. The SWFA is lighter but the Accupoint seems to have better glass and light gathering, especially at higher mag and better eye relief. Thoughts on these scope options?
I will post up some pics and summary of the build when I get it all done.
