My 2 biggest muley bucks were taken with the 250 Savage, the first buck was just a shade over 30", shot back in the late 70's with a 14" XP100, seems like about 125 yds, not sure. The bullet was the 100 gr Hornady & it took out both lungs & exited.
Second buck was a 27" dandy taken with an Encore 15" Bullberry in 250 Improved, my bullet was the 100 gr Ballastic Tip at just a hair under 400 yds. I caught him right at daybreak as he fed across a field, didn't make my best shot but it knocked him down, he got up & ran down into a steep gully & I gave him a finisher at 50 yds. This buck stayed in first place in the Soda Springs big buck contest until the last day of the season. Also took a 25" buck with the 250 Improved, I had spotted him several times during the summer, he had a favorite hay field that he fed in most days & hid out along a river during the day. I left for work an hour early, hoping to catch him out in the field before I began work at 7pm.
I watched the field until 6:50 pm, picked up my pack & turned to walk to the car, I stopped & turned around to take one last look & he was standing 10 yds out into the alfalfa, I couldn't believe it! I gently laid my pack down on a little dirt mound, nestled the Bullberry Improved on top & held about 3" below centerline on his rib cage, at the shot he folded like a wet noodle. I drove across the highway to work, called my boss & told him I had just smoked a dandy, we crossed the highway with one of the loaders, picked him up in the bucket & I gutted him right in the bucket, called one of my son's & he came & hauled him home while I went to work. I was shooting downhill at a very steep angle, thats why I held low, think the shot was about 160 yds.
If you look close you can see the 250 Savage sitting between the bucks horns, this is the 30" buck.
This is the 27" buck taken at almost 400 yds with the 250 Improved, my grandson watched me make the shot..
This is the buck I shot in the hay field & picked up with the loader. Photo taken the next day after I got home from work.
