No difference. As long as the terminal meets the BS and AS dimensions; the vectors are the same.

i.e. 1/4 ME BS 0.494-0.489 AS 0.438-0.431 as long as the terminal is within .007 of the dimension it is considered in spec by ASME. Keep a log book of the swages made, that way you can plot when the dies or spindles need to be adjusted and calibrated and prevent a catostrophic failure as the result of an incomplete swage and the sure to be litigation after.

Trick is when "mic'ing" the terminal on rolled swages, do not get confused by "mic'ing" the flash. The AS size reflects first pass dimension. Second pass is cosmetic to crush the flash down.

There is great discussion on work-hardening of the terminal...
