Ellis -
What brand / model gun to you plan to use these loads with? If it's a Glock - forget it. They have an unsupported case that causes the case to bulge. The first time you use the case it is fine, the second time you use that case it is fine, the third time you use the case you lock the gun up but good.
And the polygonal rifleing is not good with lead. To my knowledge the Glock and the H&K are the only guns to use this.
Now then, if you have a fully supported case and cut rifleing, let me know and I'll tell you what works for me.
