Re: Howa 1500 barrel help??
Howa 1500's are affordable enough. Why not just buy one with the proper bolt face and magazine for the cartridge you decide to build your custom/semi-custom on? You've got lots of issues to deal with when you convert an action designed for the .223 bolt face to another. Bolt face alterations, coming up with the proper extractor, ejector not in exactly the right place, wrong magazine, feeding problems, the list goes on and on. I'd use that .223 action to build another .223 , or improved, or a wildcat based on the .223 case.
