300 Gr. Gold Dot Obturation
I got a couple of boxes of the 300 Speer Gold Dot bullets, made for the .500 Smith and Wesson, in from Midway yesterday. These are the same diameter as the 335 gr. Ranier bullets I tested last week (.5003), and go down the barrel with about the same tension. Started out with the chronograph, using my 26" SS Black Diamond XR . . .
120 gr. of 2f Jim Shockey Gold1097 fps. Very light recoil
110 gr. of 3F Jim Shockey Gold 1753 fps Moderate recoil
120 gr. of 2f Triple 7 1989 fps Fairly stout recoil
It appears that the cooler softer push of the 2F JSG was not enough the obturate this bullet. I really need to get to the 2,000 fps bracket to gain enough of a useful advantage over other Colorado legal bullets, so the Triple 7 load is going to emerge the winner here.
Went to the benchrest next. Forgot my Caldwell Lead Sled, but had some sandbags in the trunk. I had one shot where I jerked the trigger a little and the bullet went acouple inchesleft. The other four are in a group that is about 2". This is plenty accurate enough for elk hunting.
