Blues Bear
Never tried post-its but did experiment with puter lables/sticky price tag lables on my cast .30 cals. .....one complete wrap with ends butting together for a straight seam and then one wrap of tape for lube.
Had some success but it was too labor intensive and had to use razor blade to trim any part hanging over the base area for a flush trim and no tail and just went back to 2 wraps of tape.
In the tapeing process I never found a need to stretch it to put it on...it never mattered if the boolit received 1.75.or.1.90.or .2.25 wraps.. the accuracy remained the same (once you'd already found your accuracy with that particular boolit/load )
I usually never size them before taping and use the time to wrap instead...
Have a 45/70 Lee 500 gr GC load that will consistantly shoot 1.75 inch/3shots/190 yds/1300 fps with my #3 Ruger and my B-78 as well...Tested sized vs. unsized with this load and 2 wraps tape and never saw an appreciable difference so quit sizeing them. Found the same to be true at 2000 fps with 350 gr PB with reversed GC under base of boolit.
Have recovered boolits from berm to note a thin "string " ..1/2 inch or so of tape still attached on all and some tape still in the lube grooves and is no detriment to accuracy regardless of velocity.
From all appearances, teflon tape does not require any exactness when "patching" to achieve accuracy/non leading..just cover the boolit from the base end to the front driveing band and if some slightly overlaps this band this is good, as no lead/ww touches the bore at the front.
Whether you shoot straight wall or bottle neck cases , case necks need to be belled/expanded to seat the taped boolits with out bunching up or tearing the tape....I use an inexpensive Lee universal case expander die good from .224 to .458 and then useing Lee crimp die remove the flare or crimp if i choose
So if you have an accurate load useing your favorite lube try it with tape instead, especially if its in the high velocities.
