Just a follow up on my thread........;  First off thanks for all the great information concerning my question re: 40-65. 

   After looking over my bank book  

;  I've decided to send off my recent 38-55 TC purchase (frame and fore-stock) and have a 32" BC barrel fitted.  With this then, at least, I have my base should I find the $$$ to create a 40-65 OR I can simply stay with 45-70 and shoot this as a BPCR.  
Then; if and when I ever get to either go visit the Quigley shoot or  hunt out west for 'critters larger than Whitetails I have more than sufficient rifle....(maybe using the 38-55 and the 45-70 do a combination hunt like Elk and Antelope....hummmmmmm 
 
 
).....  
Also this leaves me with an extra 38-55 barrel and as an added bonus the TC I picked up last week has a Pedersoli Front Globe sight and a (real) Buffington Trapdoor rear sight that I can move to the 32" 45-70.  To boot somewhere here I have the original 38-55 sights that came with my first TC and these can go on the extra 38-55 barrel.  A bit convoluted but it does get me both worlds so to speak.  Thanks again;  Jim.
