Savage did not make the large shank target action in a long action, they are all short actions, however if your set on a long action years ago the CIL 950 made by savage was a long action single shot, and will take the rifle basix target trigger, however since you've already got the large shank barrel this may not be an optimum option for you.
What cartridge are you running that your sold on a long action? I run a 284 in a short action, can eject fired cases but have to pull the bolt out to remove a loaded round from the rifle
