Anybody make their own? I know they're inexpensive but I'm just curious. I need one for my 50 and I've found them online. I can make one faster than It'll take to get here and It's just something to do. My 30 cal jag measures .250". Is .060" per side clearance needed for the patch? And, I would think the clearance would decrease if the bore increases...just thinking. Any preferences on types of jags too? Like knurled versus the angle stepped type? ...(the latter is my preference)
