Alot of good information here. Thanks folks. The wheels are in motion and I've ordered the adj reamer and a D reamer + blades and a long handle. I'm a little vague on 'parallel surface' so if one of you could further explain I'd appreciate it. I like that idea of modifying a snap cap to use as a guide. I have the rest of the tools. I have a small lathe to create bore size guides. I'm going to make kinda like reverse pilots. Here are the first three candidates. 94 Rem, Flues and an AJ Aubrey.
