Paper Patch

[MEHavey]

I've been playing with heavy/.45 caliber paper-patched bullets off & on for about 25 years and am always looking for new ideas/tech for this 'old tech' design.

I'd pretty much settled on Break-Free (cured in warm oven) under rubbed-on 50/50 (volume) mix of Lithium grease/MotorMica as patch lube ...until tonight... when I got a wild hair (hare?) to try STP. `Let y`all know tomorrow.

But... are there any other practitioners of this black art out there?

I use teflon tape,wrap it bearing surface of the bullet several times resize and gas check using lee resizer a thousand over bore do not know if other equipment will work Have driven 30/30 Win with cast bullet in this cofiguration at 2100fps with little to no leading promblems

Well, today's trial showed the old stand-by, BF+Li/MotorMica,to work well -- 2" groups -- (again).

STP did not. (Put a '1' in front of that last '2').

It appears that the STP doesn't soak through the paper layers like Break Free does, leaving dry paper layers underneath -- even w/ Li/MotorMica rubbed in afterwards.

With the BF/Lithium/MotorMica combo, it effectively turns the paper into a Teflon-like layer... even fooling many people today to look & feel to then ask, "...is it Teflon?..."

post: The best I do with that load of a 570grBallard/PP over 100gr/1F over 10g IMR4759 is 1500fps, ... and that does an impressive job (both in front of and in back of the rifle.)

which worked quite well, but I gave up PP bullets (in 11mm and 45-70) because I would get these tiny 2-3 shot groups, then I would get an unexplainable flyer.

Not worth the considerable time and hassle and plain old precision case bullets worked better (at least more consistent). I think the only potential advantage to PP bullets is the abilty to use dead soft lead bullets (at a tiny bit greater velocity), but who needs this when you can go 30 or 40 to 1 with normal bpcr techniques. I also suspect that PP bullets are hard on bores (yep, paper WORSE than lead/copper--at least that's what the olde timers said).
