Let me dig around and find it. I don't have any modern tables, but just results of Joseph Whitworth's tests and some of the small arms trials in England. I've got stuff scattered everywhere and it may be a little bit before I can get it together. If you're in a hurry you can go to:
www.lrml.org/technical/index.htm
and you can find information about Whitworth ballistics, history, etc. It even has a report written by Whitworth about the technology that he developed.
As for original Whitworths, the only ones I've got to see were behind glass cases many years ago so I can't tell you first hand about details on those. As for reproductions, I have a very low serial number Parker-Hale which I bought used over 20 years ago. The barrel is round and tapered. The outside diameter is basically the same as an Enfield rifle musket barrel, the only difference being the bore diameter. At the muzzle the O.D is .808 and at the breech the O.D. is .991 on mine. The breech diameter may be off a little since I didn't take the barrel out of the stock. Therefore, the wall thickness is a good bit greater. It doesn't really square off at the breech, it flattens at the top and looks like an extension of the tang.
There are no ramrod thimbles on a factory (original) Whitworth nor the repros. Some Civil War Whitworths were halfstocked after the War though, and had thimbles attached. Most all of the Manchester made Whitworths were 2 band rifles patterned after the Enfield. They were also stocked nearly to the muzzle and wouldn't accept a bayonet. Enfield Armory made Whitworths were similiar, though some had 3 clamping bands holding the barrel on. The trial Whitworths made at Enfield were identical to the musket except for the caliber and rifling. A few rare ones had a .564 bore and 1 in 25 rifling. Imagine the weight of that bullet! Mine measures .485 across the corners and .448 across the flats of the rifling.
The Parker-Hale Whitworth is patterned more after an Enfield rifle musket. The barrel at 36" overall is 3" shorter than the musket. Most original Whitworths had a 33" barrel, and others had a 36" barrel. The actual bore depth of mine is 34". It does have a standard breechplug, which when removed reveals the fact that the back of the breech is solid. The breech, containing the bolster, is screwed into the barrel. It apparently is solid in the rear. Though making the breech area stronger, it makes removing a stuck bullet by driving it out from the rear impossible without removing the entire breechpiece. I don't know if they still construct their barrels this way. I can see that the new Whitworths sold by Navy Arms are a little different in detail from the one I have, and all of the repros that I've seen including mine are sold with Enfield musket sights. Mine does have a globe front sight, and I believe the new ones do too. Many originals have a blade sight on the front. One thing that I wish was included on mine is provision for attaching the Davidson scope. I'm rather surprised that they didn't do that on the early repros. If I had the guts to do it, I would seriously consider making the fittings for it. I have noticed that the quality of the new rifles is not quite up to par with the early ones and of course none can match the originals.
As for the comments I made about recoil and stock drop, don't take my word for it. That's just my experience. The way you hold your rifles is no doubt different than mine. I'm used to more drop from firing longrifles and Springfield muskets. The Springfield's drop is not much different than the Whitworth or Enfield but the butt plate shape is, and that would be a factor. Some people find the Enfield type stock to be quite comfortable. Actually, I do myself, but this gun does kick hard with a standard load and there is a straighter line from muzzle to butt than on most muskets and rifles.
I hope you can make something of the mumbo-jumbo I just wrote and that it will help you. I'm hoping to take mine out Saturday and do some plinking with it at 100 yds. (All I have) I'm wanting to experiment with lighter loads and see if they will upset the cylindrical slugs I use into the rifling as well as the heavier loads do and also see if the factory sights will work better. I'm looking at adding a Vernier tang sight later as well as a new front sight.
If you can't find the ballistics table on the above sight, let me know and I will try to type up something from what I have if I can find it. And if you have any other questions feel free to ask and I'll try to answer the best I know how. You've probably discovered by now what some of these other guys already know. I'm pretty windy. :yakyak:
