I have always like the eight point to me it makes a nicer crimp So I think it is up to you on what you prefer I don't think it makes a difference in pressure but maybe someone knows better then me on that

 

I tried both 6 and 8 point crimps with new Cheddite hulls with the 1oz Lightning steel loads a couple of years ago. I couldn't tell the difference on the pattern board. Although I read that 6 point is better for new hulls, I found the 8 point crimp looked better and stayed tight, so all my loads are 8 point.

Obviously with previously fired hulls that decision was made for you. :lol3:

 

I've "heard" both are better...
I haven't used enough new hulls to form my own opinion.

 

hi,

other than a small drop in pressure when using 8 pt (500-1000 psi), they're exactly the same and is more a question of what you like

cheers,

I found the exact opposite especially with steel hunting loads, 8 point crimps usually give slightly higher velocities and pressures. Not enough to worry about but it's there. Think the 6 point crimps are much easier to make with new hulls than eight point also.

 

I seem to get less crimping errors on used hulls that have the 8 point crimp. With 6 point I always seem to get a few that has one point that won't fold right.

 

In my loads both 6 and 8 crimps get Geap finished so their crimp tightest is the same I can't imagine them being different ?

 

I just love 8 point

strange really, although i only tested lead, but the more folds you make the easier should be to unfold thus reducing pressure.

I think is steel that acts 'strange' compared to lead :smile:

 

Don't believe what you think , you should believe more is better like with most things ! :yes: :lol3:
Lead loads with 8 crimps are no different than Steel loads , if Gaep'ed ....haha

 

I'm Italian, all my sells are finished with a spinner to standard heights .... i know no different :wink:

but looking back at all my tests, the 8 crimp does produce lower pressure....risible amounts TBH, still averaging lower (better?) :smile:

 

Never noticed any difference. Never tried to change one to the other. New hulls I normally use 6 point. Fio hulls seemed to be the worst. I would use a hairdryer to heat the hull up. Even then they didn't like to make a good crimp. On the second load they would crimp nicer.
