Welcome to the site!
How about a Savage 12flv (left handed model) in 22-250 for around $500, then sell the barrel and rebarrel in .243?
The bolt face should work fine, as long as the magazine would work. You'd be out the cost of a new barrel, but you'd end up with heavy barrel .243 in a left handed rifle.
If some is good and more is better, then too much is just right.
My mind is a raging torrent, flooded with rivulets of thought, cascading into a waterfall of creative alternatives
