I have pondered this too, and I am going to do both because I can't come up with a compelling reason other than total cost to do one over the other. The builds I want to do the costs will be pretty similar as well so it's more or less double the budget of either. My goal is to have a nicely accurate AR based rifle to run suppressed for hogs, coyotes and maybe a deer. If I get multiple hogs in the open I want to be able to maximize the number of hogs removed from the ecosystem LOL. Then the bolt gun I want to also run suppressed but looking for very fine accuracy, this is more for fun shooting and punching paper, being able to shoot more than I can with the big 7's and 30's and learning long range shooting. With a 6.5 manbun and a 308 I think a 243 will complement them well and keep heat managed on all three.
