I just purchased an Encore barrel in 45-70 chambering. I am currently having a gunsmith do a little custom work to the barrel. I am having him do a MB, and install a Skinner rear ladder sight. I asked him to do a casting . The casting measured .4575 at the breach, and .4582 at the muzzle. I normally cast a Lyman 405 grain bullet for my 45-70's.
I have a Lyman sizer. Normally I size my 45-70 bullets to .458. What size do you guys think would be best for the barrel measurements I listed above?? Thanks, Tom.

I want to see how people handle a bore that tapers the wrong way...

Ouch!
I am thinting 458-459 cast on the softer side. But I do agree with Dale.

You guys are not making me feel very good about this new barrel??
I did have the measurement done by a professional. If a normal guy would have done the measuring then how many of us normal guys would have been able to detect any differences at all??
The actual difference in 7 Ten Thousanths!! Do you guys think that will make that big of a difference?? What is the tolerance of the barrel suppose to be?? What are the tolerances of the normal cast bullet barrel??
What can I expect if I lap the barrel??
Normally you guys have some great answers-So help me out here?? :confused::confused::confused::confused: Tom.
