Thanks for that load. I haven't tried Power Pistol in several years, is sounds like time to give it a try again. Just have to find it on the shelves. Quickload puts the Lee 158 RF at 1507 FPS out of the 20 inch barrel at only 23k PSI.
I've owned several Rossi 357's and 454's, along with a Browning BLR and other Savage rifle's (bolts). A wide range of quality and price points. The Henry is a solid feeling gun and right up there with the best I've owned, and the octagon barrel is heavier than a round barrel, . That makes for some smooth shooting. I prefer the brass reciever and think it may help with the smoothness right out of the box. When it is dirty and gets some swirls or scracthes it polishes right up with Flitz.
There are a few main lines of lever rifles. The Big Boys are all brass receivers with octagon 20 inch barrels and handgun calibers of 44, 45 colt or 357. The 30-30 comes with either a brass receiver and octagon barrel or steel receiver with a round barrel, it's a little lighter. The 45-70 is a steel/round setup, with "rumors" of a brass receiver/octagon version coming.
Then there are the rimfires, which is what much of this thread talked about. There seem to be a bunch of different versions, with the round barrel / steel version that can be had for less than $300 from Buds. The rimfire line is the only line that has zamak used in it's construction. Including the Golden Boy that has a brass cover over the receiver. The vary widely in price depending on on the specific model. A octagon model with brass I'm sure is a lot higher in price than the $300 model. There are 22 mag and 17 HMR versions too.
There are a few other speciality rifles too.
Unfortuneately I had to use their customer service, my own fault. They just blew me away with their great service, per my original post.
