2.93 lead should weigh closer to 11 Pounds.
Joe it sounds like you have used a lead projectile this big before.
Did you have any pressure problems or did you reduce loads to keep pressure down. I don't think it would take much prssure to expand th skirt. How ere the ballistics...Is a lead projectile like this a one range load or doe it work at short and long range?

subdjoe,
It sounds like you are shooting a full scale Ordnance Rifle or Parrott Rifle. Tell us what you have and post pictures. Grin

Full scale Ordnance, built in 2005 by Steen. I had cobbled together one of roughly those dimensions just to get the rough weight, it wasn't a mold I could use but once. It weighed about 9 pounds. The nose section may have been about 1.5 rather than 2 inches thick. It was an experiment, but it did go down range with reasonable accuracy - first live fire and getting the hang of the sights. I also tried a solid lead slug about 4 inches long - cast in a 14 oz vegetable can. That did upset into the rifling.
Pressures did not seem excessive (vent plume looked normal) with a 6 oz. charge of cannon grade. Only shooting at about 300 yards. We also tried some actual bolts from Trail Rock - those were great. Pretty much dead on.
One like I described I would think should be good to at least 1000 yards, maybe more. It may be on the short side, need to experiment on it some.
