:)Slickest, While my favorite .22 cal. is the .22-250, or one of its close rivals, when you talk p. dog shooting you will hammer the throat in that caliber very quickly if you get it hot...It had several go in about 4400 rounds shooting p. dogs..now I did not baby them...if I were getting a dog rifle, it would be either a .222 or .223...today the .223 makes the most sense...My .222 has over 7000 rds though it and it is super accurate...It shows less wear than my .22-250 AI with just over 2000 rds. down the bore....If you are going to do volume dog shooting, and can find it you will do your self a favor to get a .223...roper isright with taking a couple rifles if the dog town is big...here they are mostly shot out, or under private control and the volume of shooting is not that great...Plus if you shoot public land, please wait til they have their young..Soo many IDIOTS start shooting as soon as the dogs come out and wonder why there are no dogs next year.....
