Got out this morning at the crack of dawn (it was already 82!) and did my chronograph work. 5 shot strings; chrony set at 10 feet from muzzle.
The four 185 grain reloads clocked at: 980fps, 988fps, 978fps and 990fps.
The one 200 grain reload gave 941fps
The Hornady Zombies delivered 998fps
The Federal Guard Dogs clocked at 929fps
The numbers are of some interest to me, but since I'm interested more in the bullets' performance, both expansion and penetration wise, I graph them primarily to test how close to my reloading guides estimates they come, and to verify that I'm not loading too hot. In this case, they were all pretty darned close, and none showed any sign of overpressure. I used two different powders : Unique and Bullseye, and CCI Large Pistol Primers. All brass was Federal head stamp.
