I was visiting another site and a poster over there reported using teflon tape in lieu of lube. (What? Something else I hadn't heard of? When will it end?)
I've read that Ed, in his NRA research, used dry teflon on paper patched bullets. (That was part of my education after learning that folks were pushing paper-jacketed bullets to metal-jacketed velocities.)
I realize that, for field applications, metal-jacketed velocities isn't what we're after -- but this seems a little different. He's taping-up gas-checked bullets and sizing them so the excess tape is moved to the lube grooves. If I'm reading this correctly, he also cuts away any tape above the case mouth.
The big deal? He doesn't report very tight groups -- just no first shot fliers and no fouling no matter how many shots are fired. Hmm...
So: Has anyone tried this? Is there any merit in the idea? Is there another way to avoid cold barrel/clean barrel fliers?
