halvey- performance on 'dogs is fair-to-good. ricochets are rare, and the prairie dogs are killed. they aren't quite as explosive as v-max's or bt's, but certainly more impressive than soft points.
here's how i rank what i have used*:
1- hornady v-max: more explosion and at least as accurate as smk's. no ricochet. the 'gold standard' in varminting bullets.
2- sierra mk's: fair explosion, good accuracy, no ricochet.
3- sierra sp's: no explosion, decent accuracy, some ricochet.
4- nosler bt: good explosion, good accuracy, no ricochet.
*i have used many, many others, but these are the only bullets i'd put on a dog town again. most notably are fmj's... downright dangerous on a dog town... not only is there no explosion, but you wind up w/ dogs crawling all over, wounded, and ricochets go a long, long ways completely out of control - even worse than a 22 rimfire on a dog town.
