I haven't, yet, I keep thinking about the shortcuts but wonder if I will be happy in the end. I need to look at one, I've seen none on this area yet. My original plan was to find a pre-64 featherweight 270, disassemble it and keep the original parts.
Keep in mind the 270 fwt's demand much more money than the 30-06 fwt's since they made less of them. my most recent 30-06 fwt cost me $800.00 (you've seen the condition it's in) the 270 is going to bring twice that (if not more). If you are looking for one to just tear apart (and re-barrel to 270) the 30-06 would be a better candidate and they're easier to find too.
