so, can anyone tell me how too much crimp can be bad and how too little crimp can be bad?
what does the proper crimp help do besides the obvious, headspace and bullet compaction on feed ramp.

how does it effect powder burn, pressure, cyling of the weapon.

i think i need to move to another powder

i am using wst with 5.1gr at 1.090 oal.
i am using a winchester fmj bullet.
i use a wolff spring at 15lb
if i have a full magazine i get a type 2 malf (failure to extract. i can see brass dings on the forward ejection port and the brass gets thrown forward at times.
this load chronos at 1180fps though.

so i was wondering if crimp could be a part of this????

any ideas?

i could use it...i have a ton of this powder,well, about 8lb's actually

thanks in advance.
