Parson, that is some nice yodel dogs and a nice Bee. Looks like your son likes it as well.

I know I like mine a lot.
I have used Seirra 40 gr. hp, 34 gr. Midway dog town, 45 gr. Winchester hp and all of them work great on yotes. The 34 gr. is a good small varmint load but I have got a yote with a frontal shot at about 80 yds and he hit dirt like he was a magnet.
The 45 gr. winchester loads are factory loads and are very good out of my rifle. They seem to hit with more authority and reach out good as well. 150-160 yds on yotes and could probably go a bit farther but then I have my limits also. With a real good solid rest and bags I can hit p-dogs out farther but with a shooting stick I am not steady enough for small targets.
Good shooting!!!
