Well, yep. It does.

I used Woodleigh 500 grain FMJs given their wind by 70 grains of AR2206H for a blazing-fast 2063fps. I don't want to talk about my first shot out of embarrassment, but my second one just moments later dropped him, and shots three and four were probably unnecessary.

Some of you may remember the drama I had when I bought this second-hand Rifleman's Rifle (Winchester Model 70). It now works a treat and now all of my rifles have accounted for at least one buffalo each.
