Finally received my Hornady Lock n Load and am about to turn in my form for 1000 free bullets. I only shoot 9mm, .223, and .308 and I have 1k .223 on deck that leaves me with the 9 and .308. Choices they offer are the .308 150 GR SP and GR FMJBT. The end goal is to start pushing my hunting rifle in the direction of long range shooting, would these rounds be worth it or would I quickly decide I would want a heavier round and then have a bunch of bullets I never use leaving me wishing I had 1k 9mm for plinking instead?
