72 caliber rifle bullet options

[donnieol]

Hi Veral;
I have a Pedersoli 72 caliber black powder double rifle on the way, it has a bore of .720 and a 1/75" rifling twist.
I Plan to use Swiss FFg or FFFg Black Powder to work up a load.
I know a patched round ball will work but I have read about people using a 770 grain bullet with a load that will group with both barrels at 50 yards.
I'll try to post a photo of a bullet cast by Sean Murphy in South Africa beside a 58 Minie' and a 45 conical

I'm very interested to hear your thoughts on ideas for a bullet and mould for this gun as well as wads and patches.
Thanks, David

Be careful with bullets in double rifles. The recoil from the first barrel will pull the bullet on the second and make air space.

I would also shoot your new rifle first with balls and see how you like it. I shoot one of those rifles quite a bit, and I can tell you that a 535gr. ball at 1500 fps over 5 drams of FFg kills well, is flat shooting, and has plenty of recoil. A bullet twice that weight will not go very fast or shoot flat, will kick tremendously, and won't gain you anything.  Something to think about.
