Youll end up with a 30 cal can anyways. Most people end up with a 30, 45, and 22.That’s what I like to hear! I heard the sierra 5 inside of a building without ear pro and was very impressed. I thought about going the sandman route originally to open up the caliber options, but honestly I only have 5.56/.223 guns right now and don’t plan on having anything else for a while
