Does anyone happen to know the length of a 70gr .257 bullet? Thinking of building a .257, but not sure if the breech I want to use will accommodate a .257 bullet with or without modification.
I've had two condor with barrels .17 .22 .25 .30 .35 cal the barrel is very easy to mechanize only need doing a little lower in the barrel and make two spile. If need some information contact pm.
