Well spent a few hours at the 100 yard line this morning---------the cool factor is something with paper patch loads--this is a public range and so has lots of different shooters ----i got comments of "Paper Bullets?????"--(i didn't even fields that one) to, "that can't work"------
Milk carton over powder and a "Wasserburger Wad" under the slug shot to about 5 inches at 100------had some blow back on the outside of the cases-----------confetti and some pieces that were "browned" ,i'm betting on gas leaking in both instances
Seems the outer wrap confettied really well----like can't find the pieces cause they blew away---have some postage stamp size pieces, that show some rifling marks that did not cut through the patch------------also the wraps around the base of the bullets were cut almost all the way around the base-------i'm guessing that travel over the chamber transition and obturation snipped that corner.
Second test was the same components with a 0.150 lube cookie between the milk carton wad and the "Wasserburger Wad"
No blowby this time amd no browned paper
The group closed to 3-4 inches at 100 yards-----seems pretty good for a first rattle out of the box-------
shooting was off bags on the bench---------betcha it closes up off sticks
other load details are
remmington brass fit to chamber length---a
nealed case mouths
CCI BR2
72 grains Swiss 1 1/2
i picked up the tracing paper at a local art supply-----"Masters Touch" measure 0.0017 thick
BACO 500 grain Creedmore 30/1
dry wrapped
barrel looks like it has been polished inside-----------NO LEAD
next test will vary the charge from 70 to perhaps 78 grains
and some more patch wrapping practice will help with uniformity
Thanks for everyones help-----------always looking for feedback to improve
Dave
