Geedubya,
It’s easier if you just swap out the barrel...
I.e. - My Sako 85 has a 280AI Krieger barrel on it,... but in the safe is a 9.3x62 barrel in case I get all excited about it again.
10/4
Over the last few years I've managed to forage two wood and one synthetic receiver and barrels chambered for the 243 Win., 7mm-08 Rem., 300 WSM, and the 9.3 x 62 and bolt heads to run them along with saddle mounts for each barrel.
ya!
