I got the .338 Edge bug and decided I would use a Savage action as the foundation. I bought an old 110 long action and have run into a few problems. I bought a Rifle Basix trigger and found the action I have is so old it does not lend itself to the after-market upgrade. It has a different safety than the newer models. Can I replace the safety and or trigger assembly with the newer style? I also bought a magnum bolt head assembly and found that it is not a direct swap either. Can I modify the bolt body or the new bolt head to make them work or do I just need to buy a newer action? Thanks for any advice.
