i am paperpatching for the 6.5x55 mm cartridge , and i noticed i had a perforator
to punch holes in paper , like the ones one uses at the office or so.
these little discs that are punched out were the perfect size for the bottom of my
casted 140 gr bullet . [lyman mould , gascheck design ].

i found some glossy magazine paper and punched some holes through it.
the obtained discs i wet with water , and stick them to the bullets base.
then i wrap my patching paper soaking wet around the bullet , and i twist the tail
until it tears off , the ends i tab and roll with my fingers around the base.
it kind of looks like the bullets from 303 guy , were the base is showing , exept
that i can see the paper disc.

shot some 25 rounds this way this evening , grouping was very good .
19.5 gr of accurate 5477 powder , federal 210 primer , paperwrap starts at first driving band , so the nose is completly exposed.
the lead bullet is sized to 6.45 mm in my homemade sizer.

nice thing i found out this evening is that i can pick up the mentioned discs at some five yards from the muzzle , and that they are fully intact !
so , the bulletsbase must be very well protected this way .

Interesting, I have never tried anything like that. Keep us posted and perhaps you could give us some photos. That would help me, anyway, to visualize things.

A "Hollow Punch" set you can get at a hardware store would be great for other cals too.

So far, I've just used them for keeping my nasty homemade lube away from the powder.

this is my set up.
notice the little round discs , theyre made with a perforator like one uses to punch holes in paper so that they would fit in a map.
these discs are just the right size for my lyman 140 gr loverin style bullets.
i wet them in water and stick them to the bottom of the bullet , then i wrap twice
with a soaked in water patch.
the end of the patch i twist off , the little edges i bend over the base, the disc is visible , looks kind of .303 guy bullets , wich is also the one who let me to this idea.
the discs i punched out of advertise material , like a glossy paper.
its a little more rugged than normal paper , and the thing is , i have found some discs
after firing the cartridge , unburned and in one piece , so if the discs survive i m pretty sure that the bulletbase is perfectly secured by them.

another thing of interest would be that the bulletbase is critical to accurasy.
a little offset would distord the bullets path somewhat when leaving the muzzle.
with these discs i know ill have this potential problem solved.
