I posted in the lube section (http://castboolits.gunloads.com/showthread.php?t=171302)that I had an interesting experience with coating aloxed boolits with graphite.
Last night, I loaded five each of 48 gr. unchecked Bator boolits over 1.0 to 2.4 grains of Bullseye. I just got in from shooting the test. A photo of the target is below.
CRITERIA:
> 48 gr. Bator boolits, .225 as cast, no checks. Seated to bottom lube groove, seating die set to straighten case mouth flare, no crimp.
> Straight wheel weights, 2% lead free plumber's solder added for fill out.
> One light coat of 20% mineral spirits & 80% Lar's Xlox, fan dried for two hours. Lightly dusted with 4X fine graphite and towel tumbled to remove excess.
> Bullseye, 1.0 to 2.4 grs. in .2 grain increments, no filler or locator.
> Lake City brass, dated 2005 to 2010.
> CCI small rifle primers.
> Tasco 3X9X40 scope set to 3X.
> 5 shots per group, fired at 50 feet from Lead Sled on three legged table.
Look at the 1.4 and the 2.2 groups. Except for a minor difference in vertical POI, it's like there are two distinct points of deminished returns. Considering that all these reduced charge tests were a result of wanting a reduced load for 'coon hunting at relatively close range (50 ft.?), the 2.4 group is also very useable. I also noticed that all the groups in this test were considerably better than all the other tests using only Xlox as a lube.
