I have a LRPV RBLP with 22-250 and 6BR barrels. This is the first Savage rifle I've owned and I'm still unsure of all the different actions and their possible configurations. What I want to know is can I install a magnum bolt head and 7mm Saum chambered barrel on my action? The loading port seems plenty large enough to accommodate the short mag round. If it will work what other parts will I need to change besides the bolt head and barrel?
