hey guy's kinda new to all this so please bear with me. i have a savage 12 22-250 that i think the barrel is getting shot out. (about 3500 rounds). i would like to put a .204 barrel on it with a fast twist for shooting heavier for caliber bullets. where can i get a barrel for it. i would like a slimmer barrel than my 250 and am planning on getting a new stock for it. thanks in advance.
