I am getting ready to load ammo for my Westley Richard 1871 Express rifle in 500 No.2 Express. The bore is Whitworth rifled. If I can make this gun shoot I hope to use it on my bear hunt to Manitoba this September.

I am concerned about the shooting round bullets in the polygonal Whitworth bore. I am asking for your opinions on this.

The bullets I have available are as follows.

1. CBE .510 440 mould. This seems the safest option shooting malleable round bullets in a polygonal bore.

2. Woodleigh .510 440 grain RN SN. These bullets have a thinner jacket designed for Black powder express rifles. I would think they should be fine in a Whitworth bore. I have 55 of these bullets.

3. Barnes Original .510 450 grain. An unknown to me.


Would like to hear your opinions on these bullets suitability a polygonal bore.

FWIW, i will be cross posting this question else where to get additional opinions.

My research so far indicates Whitworth rifling of the  Muzzle loaders was different than that of the breechloaders. Mine of course is a 8 groove breech loader.

Here is mine,

I am  looking at groove diameter jacketed bullet in this bore and any reasons why I shouldn't.

waiting for James Bond to walk across the breech end- isn't that bassakwards of the movies?

The old Barnes bullets could be had in a thin and a thick jacket. This was in the late 60's when the word was that the copper jackets were made by using a Jeep to stretch the copper tubing. IIRC, the .035 was the thin.

Here the latest that i have learned on this.

A lot of people know about Whitworth  Hex bore, not many know about his other  barrels-especially the octagonal ones.

THe nickel based copper tube bullet for this cartridge were a nickel gas check and copper tube down the center of the bullet to aid expansion.

The current Barnes originals, per  Barnes are .035" thick copper jacket.

This barrel slugs .501 minor diameter-across the flats.  .527 major diameter, across the corners.

Paper patch would not be more correct, it was just one of the options at the time.

Hawk does offer a .515 diameter bullet. Close, but not close enough.

I have order .527 mould.

If James Bond was a  Victorian, you might see him in the bore...

A long time ago I took a dizzy blonde out to a real fancy restaurant near Seatac airport. Fish at about eighty bucks a plate, two waiters in white tuxs with towels over their arms. Classy joint. This dizzy blonde is wearing a leather dress and one side was black while the other was white. Her top was matching but opposite and black and white checkered leather cap. There was at least a dozen people waiting for tables so we had to wait. The hostess, a young blonde chick asks for a name so I said, Bond, James Bond. She writes it down. Twenty minutes later she comes in and says, Bond, James Bond! As we walked by this guy waiting, he remarks, "way to go double O". I had way to much to drink at dinner and was lucky to have held together.  I love those old James Bond movies.
