The point I was going to make is that this big bore subsonic rifle concept is relatively new but most lessons learned by handgun hunters over the last 80yrs can be applied. A .45 caliber rifle slug at 1100fps is equivalent to a .45Colt handgun load and handgunners have killed a lot of critters with those loads. I think some folks have the false impression that a 600gr bullet is going to hit harder than a 300gr. It's only true if the quarry is large enough to warrant a 600gr bullet. On critters like deer and average sized hogs, it's a complete waste of good lead. A 300gr is going to exit on those critters so the added weight of a 600gr bullet serves no purpose. It doesn't hit harder, it just goes deeper into the ground after it exits the deer.
