This is some really basic stuff. Mebbe a copy of The ABCs of Reloading is in order. Yes you can crimp bullets with or without a cannalure or crimp groove. Most roll crimping is done for revolver rounds and crimped into a cannalure or crimp groove. Semi-auto cartridges that headspace on the case mouth most often use a taper crimp. The 45 ACP, which headspaces on the case mouth, uses a taper crimp (not really a crimp, just "deflaring" the case mouth for good chambering. Double check your load data; powder charge seems a bit light to me. (which would account for the failure to eject). How does you gun cycle?

If you're gonna use Hornady bullets I'd suggest a Hornady reloading manual for load data...
