Heavy Lead @ 200 Yards
Well guys, I'm not ever going to compete with ronlauglin when it comes to long distance shooting.
Two hundred yards is a l-o-n-g way for me. So here's my promised report shooting Ed Mehlig's 465 grain lead flat nose conicals out of the .45 GM/TC Renegade at 200 yards with a Cabala's 3x10 Powderhorn scope mounted on the gun.
First off, I set a target at 100 yards and took three shots to verify the scope was set for a 100 yard zero. It was. Here's the test target.
I then drew a 2.5" black dot on the back of a big 24" x 36" wall calendar and hung it out at the 200 yard marker. Here's what it looked like from the bench.
Now the guessing began. I wanted to use the BDC feature of the Powderhorn scope, but had no idea where to start so as to get on the paper at 200 yards. I studied the ballistic chart I had for that load, and thought about the drop I got when shooting at 125 and 150 yards, and then made my best guess as to how to use the scope.
Here's what I went with.
I took a very careful shot. Could not see any bullet holes on the target. Walked down 200 yards for a closer look and nearly fainted.
HOOWHEEE!!! Talk about luck.
Now we all know that kind of luck won't last. But I didn't do too badly.
Took five more shots using the same hold on the target and ended up with a 4-1/4" group. I ain't complaining.

Van, not bad shooting at ALL!! While I know the impact would be lower, I wonder if the groups would have shrunk if you used one of the other points on the crosshair ? All I know is the deer don't stand a chance within 200yds with you this year.

Yes, i know, you old timers hate moving scope dials, once you have the rifle sighted in.
Following is a ballistic calculation which should be 'close enough' for the shot at 200 yard, using the main crosshair.
The calculator say, twist the elevation dial up 10 3/4 moa, and you will hit somewhat close to the bull, when sighting with the main crosshair at the center of the view.
