It is a 45/90 on a Francotte with a Greener crossbolt.He has the liners ready and I need to get some 45/90 cases ordered. I am looking for some loads with a 400 grain bullet that will not have too much pressure. Daryl recomended that I start with 45/70 loads and go up. The only loading manual I have that shows pressure is the Lee Manual. There is a 28000psi load that develpos 1926 fps with a 400 grain. I would like to have more horse power than that but have not found pressure specs. When Richard Stallcup get the gun regulated, a new pad put on and the checkering recut on the fore end I will post pictures. If any of you guys are thinking about this, he would be a good man to talk to...reasonable prices also.
