Sorry if this has been discussed before, or if its common knowledge. I'm just getting into 300blk with a 9" pistol. I see the lighter 124gr rounds and then 150-ish grain rounds, and then the heavy subs. When would/should i prefer one weight over the other? Does the 124gr have any advantages over the 150gr, or vice versa? Subs seem fun because they are so quiet, but seem to have some poor terminal ballistics. I want to start stocking up on it, with sme being SD ammo and a large portion for plinking.
