I am preparing to firelap my SRH .454. I was wondering if anyone else has done this and if so, how many round were needed to accomplish this task? I will be using the method outlined in the technical manual here at BTB. Also the gun has had only 20 jacketed Corbon loads shot thru it.

Trapper,

Don't be surprised to find that it takes well over 200 lapping loads to fire-lap the constriction out of your SRH where the barrel shank screws into the frame.  I'm not sure what Bill Ruger uses for barrel steel on these stainless revolvers, but it is some of the most abrasion resistant alloy I have ever seen... if Uncle Sam will allow it, our great, great grandkids will be shooting these guns!

Note, that the above recommendations for numbers of lapping rounds is assuming you are using cast alloy bullets of a BHN of 11-12, and NOT jacketed bullets (a whole other can of worms)

Hope this helps!

God Bless,

Marshall
