I have a antique rifle that I am trying to make some shootable ammo for. After slugging the bore I find it has 3 lands and grooves and the groove diameter is .330- .331 hard to measure with 3 grooves .
The rifling is approximately 1-22” so I need to keep the boolit fairly short as the cartridge case is only a little over 1” long. The closest boolit I can find to use is a .321 dia. 150 gr. and wanted to know how many wraps it would take to get this up to .331 and would this work ?
I have never done any paper patching before but this is really just a experiment to see if I can make ammo that will shoot for a 160 year old rifle .
If your wondering about where I am going to get the right size rimfire brass for this, I am working on that also using cut down 32-20 with a rimfire blank installed in the bottom.
So can a bollit be wrapped with 3 or 4 wraps to get what I need and will it fly off after leaving the muzzle ?
Also the .321 bullets I have are already lubed, can I wrap over the lubed grooves or does it have to be removed ?
Thanks, Jedman
