I’m a relative newb that has thus far only loaded various flavors of WC and SWC’s in 38 and 357 at target velocities. I ordered some FMJ 158g from NER thinking they’d be good for full 357 Mags and noticed after ordering they have no cannelure or crimp groove.
My readings have lead me to believe that the taper crimp is appropriate in this situation but will it provide enough retention for full house 357? Thought I read for taper crimp in 357 once to keep it below 1000fps. So maybe still roll or FCD on these for a little more bite?
How would you utilize these:
A. Taper crimp but keep velocities down?
B. Roll crimp and load as you please?
C. Taper crimp will be fine at above 1000fps?
