Best I can do here at the farm with a caliper says the RDF has the shortest base to ogive length by a rch at .740, 147 horn went .744, 150gr SMK went .770.

I'll be looking for 29-3000 fps with whichever bullet is most accurate, 28 inches of barrel and Retumbo should get it there, BR2's to get it lit, this is going to be a fun project, package will leave for 'Smiths tomorrow.


Cartridge base to bullet ogive right? Measurement should be 2.xxx”. I use one of these but there are others.
