I've been contemplating that for the past couple of years. I have decided that a 7mm-08 works for everything I will need it for up to and including elk. I hunt groundhogs all the time in Ohio, and since I reload, can use the v-max's from Hornady, or tnt bullets from Speer. Going to MI for deer, I can use any regular 140-150gr. loads, and things bigger, can either switch to a bonded style bullet, or go to a heavier 160-170gr. bullet. I'm also branching out from cast bullets with revolvers, and am trying them out in that 7-08 rifle too. Haven't had alot of time to work on them this past year because of the military, but once I get things worked out, they will make a very cheap practice load/varmint round. Would work on deer as well. Just my thoughts on the matter.
