Hi, i’m a new member here. I was searching through my local armslist ads and came across a Remington Rolling block 1. The guy knew very little about the gun as I knew very little about it too. But, the price was very low I thought so I did a little research and just bought on a whim. So, now im tring to find out more on the gun. The guy said it was a 50-70, but After I got it home the bore measures .446 and a 45-70 fits nicely in it. So, im going to do a chamber casting on it to know for sure. The gun is in overall great condition. Bore is shiny, action nice and smooth, wood is great, trigger is nice and smooth with about 5lb pull. The stamping on the receiver tang is as follows. Remington ilion, NY USA pat may 3, nov 15 1864, april 17th, aug 27 th 1867, nov 7 1867, nov 7 1871. These are the only markings on rifle. The action has a half cock safety too. Any info would be appreciated.
