You must be a mind reader<SMILE>

I have reread all your posting's and a few others that have done the 45/120 Nitro and it will get right there into 450NE range. The two gunsmiths that I have been learning from one has a
Merkel 500 NE that rewoke the dreams I had from all the reading about dangerous game in Africa I did and a youngster, and when he told me he had something I would be interested in IE The 45/70 double. I have been learning allot about reloading for doubles. and having a blast. I have several 45/70 and the other gunsmith has a 45/120 reamer and I have a NEF Buff classic that will soon be rechambered. The difference in cost to do a 40/70 straight sharps vs 45/120 is negligible. So and as my new friend from Porter Texas said "I do suggest the 45/120".

I have a couple 45 cal barrels that would work. Now I just need to finish a couple projects ahead of this and should be able to get started June-ish. I will keep you informed.

Thank you so much for the help and ideas.
