Earlier this year I purchased a 110 in 7 rem mag from the early 2000s I think (F415393). After contacting savage about getting some spare parts, they told me that they don't carry parts or service rifles during the period mine was built. Mine has a bull barrel on it and I want to replace the action to something with a newer trigger. If I get a newer 338 will I be able to just swap the barrel and bolt? Or are the magnum bolts the same so just swap the barrel?
