i believed that the die did not touch the case body, that is why i sized about 500 22-250's yesterday with my 22-250AI bushing die.
but last week i bought a 17HH neck die to neck size my 17AH brass. some of the cases came out "straight", but some came out with the neck so bent it looked like a funhouse mirror! my thought was that with the delicate brass of the necked down hornet case, that the shoulder was collapsing on one side allowing the neck to be crooked. the RCBS die sized the neck to an acceptable diameter, and i was able to get almost the complete neck sized without the shoulder of the brass ever coming into contact with the die.
how much clearance is there typically in a busing neck die from the die to the case body?
for example, could i use a 17 AH bushing neck die to neck size 17-223 brass? body diameter at the shoulder is about .070 larger on the 223. or, why couldnt i take a 22 hornet bushing die and put a bushing in it for the 17? if that would in fact work, why would you ever buy a bushing die for every caliber with a different length?
in that scenario, would in not be financially sound to buy one bushing die for a 458 winchester and then switch out bushings to load 338, 300, 264, and then also load any cartridge with a body diameter less than the 458 with a case length the same or longer? not trying to be a smart azz, bushing dies are expensive and if i can buy one to use on 6 or 7 calibers, why not?
