So I have a lower that needs a new wife. I was looking at maybe .300 but I live in Iowa and suppressor's are a no go (yet). Better off just sticking with an upper in 5.56 and load up on heavier grains? I know very little about .300 but I've been trying to read a lot, but everybody mentions it being suppressed. Any help would be great. Thanks!

I've been down the 6.8 road and don't really want to go back, by the way.
