Brandon,
I reckon you need to find a better-size crimp - and maybe go down a size in leader. See if you can get a diameter on the material first - digital calipers for preference. Don't trust what's written on the packet, if anything. 330lb sounds like it's on the thick side of necessary to me.
I agree with Greg, three squeezes with a hand crimper should be all that is required, and as he has described. I personally like the 8-type sleeves (annealed copper) rather than aluminium, but have never had a problem with either. The 8-type are slimmer, is all.
How are you linking this material to the twisted leader?
