I did a cursory search but didn't find much. Any you guys who own Henrys do a cast of your chamber? I was hoping someone with a 45 carbine might share their numbers with me so I don't have to buy some Cerrosafe. I already have a Mihec 45 Colt Ruger mould and I'm hoping it will work. Lots of nose options from flat nose to extreme hollow point. I believe it throws 454, should be able to size down to 452...if the Henry throat is about that size. Thanks for any input from the members.
