Will do.

    Did you set one of the reloads up with a couple of drops of water to see if we can produce yellow dust?

No I haven't experimented with that, but may try to see if the moisture with the powders will form nitric acids as a reaction inside the brass casing...

   Fired one more box of 40 today and had one dud. I tried multiple times but the primer just wouldn't set it off!

EAA Pro 4.75" 1150, 1139, 1100, 1137. Average = 1131.5 FPS/ 512 LBS

In the fudge factor from the last time out.

Here is a picture of the primers as pulled, powder was fine the primers were not spent or previously shot as evident of the clean shiny anvils.  You can see the primer mixture is gone mostly, so none was under the anvil when struck.

  I tested my old box of Winchester Silvertips today in both lengths.

EAA Limited 4.75" 1267, 1271. Average = 1269 FPS/ 626 LBS. The data I have in the sheet for the new stuff is 1210 FPS with 8.4gr's of Ramshot?? I need to send The Shadow one for pull-down to see what's in there. Did we do a pull-down of a new Silvertip? Did they load the old stuff better?
EAA Hunter 6" 1331, 1366. Average = 1348.5 FPS/ 707 LBS.

  This is kind of what I expect out of the Silvertips. I think I will put this data on the "discontinued" tab as "old".

  Hunter data for the old Cor-Bons.

135gr (Old) 1400 FPS Adv EAA Hunter 6" 1557, 1520. Average = 1538.5 FPS/ 710 LBS
135gr (Old) 1450 FPS Adv EAA Hunter 6" 1587, 1585. Average = 1586 FPS/ 754 LBS

  I shot the old Silvertip The Shadow returned from the pull-down. The velocity dropped a little from the process, but nothing like the new garbage they offer today!

EAA Hunter 6" 1309 FPS/ 666 LBS. A new round gave 1349 FPS/ 707 LBS when initially tested.
