Anyone have the .45-60 WCF BP cartridge dimensions, bullet diameter, and load info?

Are you loading for an original, or is this for a new reproduction '76?

The reason I ask is that they aren't going to be the same, according to my contacts at Uberti.

Hows this

Hell, what took you so long?

Its been a long work week. been getting up at 3am all week. Just one more day of a 3am get up then i can sleep in.

hahahahahah omg i have a R&D 45lc for a colt walker. problem is i let a friend borrow my calipers. I can get you the dimensions but it wouldnt be till tomorrow afternoon have to pick up my calipers and i can get you all the dimensions you want write it out on paper with drawings. Then scan it to my computer and post it here. give me till tomorrow and i will have it for you.

Let me start out by saying upfront that this is all based on a discussion with a rep at the Uberti USA office several of years ago. I was at one time planning on buying one of the new '76 Uberti's, but never did. I have NO PERSONAL experience, so would tell you to take this with a grain of salt until you can check it out.

According to the gentleman I spoke to, There is a dimensional difference between the 45-60 and the 45-70 at the rim. He said that Uberti had cut the bolt face and rim recess to fit the 45-70 and not the 45-60. Their thinking apparently was that most shooters would be more likely to trim back 45-70 to 45-60 length, rather than try to find actual 45-60 brass.

He then told me that as a result there was a slight headspace problem with their gun if used with original 45-60 brass.

I remember looking all this up at one time, (there is an .0008" difference) and thinking to myself that the guy was full of digested alfalfa, but I thought I would pass this on.

I'm still trying to save enough money to buy one of these guns, BTW.

This agrees with what I have READ.
The first reproduction 1876 was from Chaparral and is chambered to the original specs and calls for thin rimmed brass, as made by Jameson and availble from Buffalo Arms. The Uberti is made to use shortened .45-70 brass.

I dunno about the .452" bullet business. Mike Venturino said that 1876s had some of the most consistently bored rifle barrels of the day and nearly all measure .457" groove diameter. I assume the Italians are using standard .45 rifle barrels of .458" Which would call for a .458" - .459" bullet, at least with smokeless.
