I don't need them as I have enough to last the rest of my days.
I have a lovely Martini Enfield converted to 7x65R. It shoots very well, but my aging eyes are having difficulty with the iron sights, rear diopter, front blade.
This cartridge is a sleeper, most just don't know how good it really is.
In a strong rifle, such as the Martini, Ruger #1 etc it will easily push a 140 grain bullet 2900fps out of a 24in barrel.
I was actually considering converting a #1 Ruger, presently wearing a 338-06 chambered barrel, to this cartridge. That won't happen, cases and loaded ammo are to hard to come by and to achieve its potential, you have to hand load.
I've run across RWS cases with Berdan primers.
Are those cases Berdan primed?
