Paper patch in 7.62X54

[beemer]

I have been working the Lee 312-180 and the TL-160 in a 91/30. The boolits are sized to .308, wraped with tracing paper to .314 and lubed with LLA. I have been using 44-45-46 gr of Win 760 with a half grain of dacron. The boolit is seated to the base of the neck. I believe the 180 does best but the 160 is not far behind. Groups are running 2 1/4- 2 1/2 in at 100 yds with 5 shots. I do get an ocasional flyer but with the trigger pull and open sights I am lucky not to have more. Velocity is about 2400 fps with the 180 and 45 grs of 760. I have shot a few smaller groups with J-words in this rifle but not by much.

All the best groups were using gas checks. I tried some loads without them but got patterns instead of groups. Has anyone tried putting a cardboard disk on the base of the boolit and rolling the paper patch over it. If I have the right size punch I might give it a try.

you are using both a g/c and pp?
if i had to use a g/c with pp i would forget the extra step here.

I only ever substituted a card disc for a GC on a non patched lead bullet, sitting on a caseful of powder, and the grouping went away and leading showed up. BvT.
