Just ordered a barrel for my savage 10 that I use for long range prone in crap weather. Sick of getting pounded by .308 recoil when the wind is high or when I'm out of .223 ammo . Yep, I is a sissy that way. Anyway, ordered a 26" pipe in .243Win Ackley Improved from Columbia River Arms/Black Hole Weaponry. It's in an M24 profile with the muzzle threaded 5/8x24 as one might expect. It'll be a straight taper to .900 behind the muzzle threads. I decided I didn't want to get my .308 barrel in the coral snake pattern when I could have a much better chamber inside so decided to get the new barrel now. 3200FPS with 108gn ELD-M's without even pushing it hard. All the trajectory of a 7mag without the blast or recoil and barrel life should be pretty good considering the blazing speeds and overbore case thanks to a 40deg shoulder and polygonal rifling. Also found out I can use N550 and get some pretty spanky speeds. I'm thinking of doing a test load with US869 given the long barrel. A 100% load might just work with that long barrel.
