Folks, if one was to take a straight walled case of a longer length and cut it back, would it be better to size, trim to length, then inside ream?
Say you started with a .414 Supermag, 1.610 long, and you wanted to create .41 Mags at 1.290 [no, I am NOT cutting any of my .414 SMs! Just an example!!!].
Size the cases [or not, diameters should be the same], trim down to 1.290 [the Horror! The Horror!], then inside ream to acount for thickness variations [414 SM probably is thicker at 1.290 than the .41 Mag].
