44-77-405 Test

[Denali]

Yesterday i tried to find some paper that was .0025" at several office supply store but was not successful. I loaded some 44-70-380's in unresizex cases using 3 wraps of the baco 9# to get a good fit in the case (was hoping for .0025" paper with 2 wraps). Accuracy at 100 yards was not too good 3-4".

Today i loaded my staight sided .425 405 gr roundnose using thick paper in 43 spanish sized cases only wrapping the bottom half of the bullet so i could easily chamber round after round in a fouled bore. I was banking on the possibility that the top half of the bullet that wasnt wrapped would not bump from .425" up to the .438 lands and lead the barrel. To my surprise everything worked out well with about 2 inch 5 shot groups and no fouling control at all, not even a breath down the tube was necessary. When i cleaned the barrel i saw no lead either.

I also tried using the same bullet with coffee filter paper and 2 wraps to get a good fit in UnResized cases and got about 3 inch groups and no fouling control.
77 gr kik 2f
Fun stuff to play with!

Now i have to go back to work to earn some more money for lead and powder.

That's a good tip to shorten up the paper patch some on the front end to potentially gain extra shot capability w/o fouling mgmt. It seems there is always something else to test in this game, but one certainly doesn't stand a chance of getting bored either. Thanks for the excellent tip.

office max has a drafting vellum that is quite close to what you are looking for, its in the drafting section not the paper section,

Dean what does 2 wraps added to your bullet diameter get you? Is that stuff as tough as the vellum I been using? with the 1st wrap basically uncut but unwrapped from the firing as you have seen mine do? bobw

I dont know bob ,it worked quite well with the 440 bullet but was a little tight for me . didnt want the hassle , it cuts the top layer and leaves a full marked bottom wrap.
