The only thing remaining to do on this rifle is develop a load, file and blue the rear sight. I'll try to get videos posted of me shooting it when I do some of the sight in work.

Thank you for the compliments.

I'm glad you enjoyed the build documentation. I'm not sure what the next build I'll document is going to be, the next rifle on my roster is another 2 Bore Boxlock. I've already documented one of those and this one is going to be just a left handed version of the same, so nothing new there. I have a Flintlock, chunk gun(over the log rifle) coming up behind it, nothing really exciting about it either. I don't like to do repeat stuff, so I'm not sure what I'll be documenting next.

TC1, it shoots a 1.325" diameter projectile, the balls cast in pure lead weigh 3500gr(1/2 pound).

Did you guys ever determine the range of shootable loads (charge & velocity) for the round ball??

Nice work.

Do you know if the new owner plans to hunt with this rifle?

Don't think he does but will ask when I speak to him next week.

Any chance the owner will bring this incredible monstrosity to a Hoot&Shoot? What kind of begging do we have to do?

I shot a 26# 4 Bore with no problem. This would be a treat!

The owner is actually a member on this forum, he just doesn't participate much.

I don't know if he plans to hunt with it, I know he enjoys taking it to the range, apparently it is very destructive to old truck bodies or so he's told me.

The only load data I have on it was the sight in load. This load was worked up to the specs of the Customer for accuracy and reasonable recoil. The primer pocket was sleeved to take Winchester 209 shotgun primers instead of the Arsenal Primers. The load column is 350grs FFg Goex black powder, an 1.5” lubed wool felt wad column, and a cast wheel weight(water dropped) round ball (mould by Jeff Tanner, ball specs diameter 1.325”, weight 3,376grs), Chrono average of 1020fps. I loaded as high as 500gr FFg Goex, during my load development for accuracy and tolerable recoil, but I never chrono’d the heavier loads. I can say for certain that the 500gr charges are a brute to shoot, not impossible, just not something you want to do very much of.

Very nice looking work. What distance are the rear sight leaves regulated for? 25, 50, 75, and 100yds? I imagine the BC of that round ball is about .001 and the trajectory resembles a mortar round.

Thank you.

The fixed leaf is sighted for 50 yards. The folding leaves were never sighted in. It was agreed to by the customer that he would work out the rest of the yardages. He had a custom mold made by NEI for a lighter weight(approx. 2500gr) paradox style bullet I designed and he wanted the ability to use one of the other leaves to sight for it after he finished his load work on the lighter bullet.
