Brian M, Deafdog is right it is .750, in generad terms it is the same Dia, and thickness of a linclon penny! This is handy when identifying chambering in an unknown rifle. There are lots of things about guns that can be determened by the size of several American coins. All old time "MAKE DO" trivia.

Mac,
Thanks for the info.Not trying to find out what a gun is,but am looking to have a Browning B78 rebarreld to 577 2 3/4 inch and needed the rim diameter to determin if the the action will need to be opened up.If it needs to be,the project is scrapped and I'll pick up a Sharps repo in 45/120 3 1/4 inch instead.

Brian,

Let me know how it works out. I'm talking to Ballard about having a .577 built on a 1885. They'll do a 2.75" and a 3". Let us know if you find a smith willing to do the conversion. Thanks!

That's one of the things the penny is good for. Barrel down, block down, lay the penny on the back of the barrel evenly centered over the chamber, and see how much room there is left over the edge of the penny, to determen the barrel meat left if so chambered! The case measures .659 just ahead of the rim. If you go to a 577NE in the B78, it will probably have to be re-stocked with a thicker, and wider butt stock to handle the recoil, without killing on the back end as well as it does on the front end! There is a BIG difference between a 577NE, and a 45-70! Take pictures of the first shot!!!!!!!

Mac,
There is no way on earth a 577 could be rebored on a factory Browning 78 barrel-the barrels usally only measure .6!

I'll try out the penny to see if the action will need to be opened up.

I would be doing a 577 2 3/4 inch,not the big 3 inch NE.750s around 1800 FPS.Recoil ought to be around the same as a 8 1/2 pound 458 Winchester,which I am used to.The Browning has a very straight stock so it should transmit recoil fairly well.I will though be sure to put a HUGE Decelorator pad on it.
