The more I read about top-notch mold designs, the more emphasis I seem to find on crimp grooves. Particularly with the Keith swc designs, and beveled crimp groove. Seems very solid, that there is a good chunk of meat for the case edge to grab a hold of. For high-powered loads this seems quite desirable to achieve full combustion & no bullet creep during firing. I am speaking of revolvers here, but it probably applies to all manner of gun.
The only mold I have so far is the Lee TL358-158 swc and I am very happy with the shooting and lack of leading. I am loading to a COL of about 1.57", which leaves the forward-most band out of the case, then crimping between this band and the next one. Finishing with LEe factory crimp die, light crimp for "target" loads, heavy crimp for magnum loads.
I am posing the question not to solve any existing problems, since I have not had any, but rather to head off any problems, or perhaps to make my cartridges more accurate. Does anyone have any tried-and-true COL used with this boolit, or any rules of thumb regarding seating depth/crimp location for TL boolits?
Thanks in advance, thie forum is great.
