Well I thought I'd add a little update to my .204 expereince.
I went out the other day to check the new custom turret on my .270 WSM and thought I'd just check the 22.250, .204 and the 223 as well at various ranges. All wear Leupold scopes with custom turrets.
We had a little 8-10 mph wind that day so I was interested to see what it did to the various calibers. At 300 yds the .204 (32 gr Hornady vmax) had a wind drift of over 8 inches. The 223 Black Hills 52 gr was about 4 inches as was the 22.250 55 gr. The .270WSM with the 140gr AB @ 3100 was still dead center. Even at 600yds virtually no wind drift. Of course the 600yd click was 12" low, so I've got to figure that out, but it was dead center at 300yds and started to not coincide with the turret around 400yds.
So yesterday I was out cleaning up the pd's at a local ranch and got to a field that the closest pd was 300+yds. I figured I'd let the 22.250 take over as the .204 needed a side hold over of 2" at 150yds to give the pd's a lead lunch, since wind was blowing 15mph with 25mph gusts.
Because the .270 was in the same style case as the 22.250 it was aboard instead. I was amazed to fire 5 shots at that range and kill 5 pd's. (amazed at myself, more than the gun). After about 30 minutes I took a long drive around to the end of the field in an effort to perhaps get closer shots, and took the .204 out with me.
After shooting a couple at 150 yds I was checking the perimeter of the field through the scope when a coyote stepped partially out of some tall weeds and was eyeballing the closet dead pd. Because he was only 30 yards beyond the pd I didn't bother to click the turret up to 200yds, but left it on 150, put the crosshairs on his chest and squeezed one off.
I saw through the scope, the dog fall backwards into the weeds and when I went to look for the critter, DANGED if I could not find him. The possibility exists, I suppose, that I missed, but after cracking 40+ pd's at that range and beyond that day I'm just not buying that. One would think there would be some kind of blood trail to follow with that vmax, but I sure couldn't find one.
As much as I hate coyotes, man did I wish I had my .270WSM in my hands for him. BUMMER!!!!
