Those heavy barrels are going to be a pain to antelope hunt with. Or hit multiple stands in a day. Not going to have heat like a pd shoot, so no need for the heavy barrels IMHO. BTW word is the vtr is not accurate from the reviews I have read. Look them up before you buy.

I would just buy the most suitable for antelope and not compromise between the two species. No such thing as to much for a coyote unless you sell furs. Dead is dead no matter what he is hit with. Obviously there is to light for pronghorns. If you want to go on a budget and have a good shooter look at Savage. If you want one that looks better but has the same accuracy check out tikka and cz.
