I may have to add the 220 seperately twice it dropped the pictures, so I'm working on it... ???

I'm itching for the 9mm and RightToBear or one of the other unknowns. Kevin's stuff is all 800-X... makes you wonder if he packed it in the little 9mm  :o

Since there's no such thing as a 165gr XTP...?? 

Is this a brand new Hornady bullet I've failed to notice come available?

Gun Control?  Oh yes, the theory that becoming a victim is somehow morally superior to defending yourself & your family.  Makes perfect sense.

Fixed the 220 stuff...I know you're itching for the 9mm's I should have them tomorrow sometime.  I have a few more 10mm's to do up, then I can switch the die sets out.  ;D  Like I said I'm trying to systematicly work on this, but I forgot to photo the Underwood 165gr XTP bullet while it was on the scale, I did get all the measurements of them.  The 220gr HC I took some other measurements to detail the cast bullet better.
Maintaining focus with the camera (very fast auto focus) has caused some fuzy parts in the pictures.  Not working on the tripod...free hand.  SORRY!

I think your pics are perfectly acceptable.  Still wondering about the 165gr XTP?  What is the mix up?

We should guess on the powder. I'm going to guess Big Ted's has Long Shot.

Underwood only has a 165 fmj and 165 bonded in its lineup.

That particular 165 grain bullet could actually be the ZERO brand bullet which is very simular to the XTP styles in that weight...that is the key is the weight and diameter...

I never knew Kevin to use anything but XTP and Gold Dots. It was an older box though so who knows.

Years ago before 40S&W took off, Hornady did make a 170 grain XTP to match the old Norma weights, their 170 and 200 grain lineup then were bullets that were more of a Turncated Cone profile that the current radiused profile we see today.
