Been digging up some new rifles ideas the last couple of week.

Ran up on a sako L579 in 243 that has been “Ackley Inproved”. As I understand it they neck down the cartridges to allow for more powder (hotter load) to it will have better speed.

Questions:

- is any work actually done to the action? I may build off of it down the road
-can it shoot factory loads if I get tired of reloading?
-would rebarreling take it back to a 243? Or another caliber if I chose ?
