For HD, I would be comfortable with the SubXs if no other option was available. They are great fun and rounds like the SubX are effective for their purpose. I prefer supers over subs for a HD or duty round, but do not dislike subs. That said you can play the odds though and find ammo that will do what you like over 90% of the time (at least). It doesn't always work out that way because some bullets that's just how they are. Speed often time winds up with at the very least cavitation on target, which is a desirable trait for sure. There are exceptions but they are just that, exceptions. That said I do plan to keep the blackout handy, if for nothing else that undesirable animals or whatnot creep up into my yard and I need to take them out without alarming the neighbors.Īs far as why supers vs subs, I would venture to say that most bullets are speed dependent to get terminal performance. I live in a very rural area so a light is pretty much a requirement. A big part of that switch back was mainly because of how the rifle was set up (with a light a so forth) whereas I still need to buy a new light one for the blackout. That said I recently switched back to my 10.5 5.56 for true HD situations. I have not shot any of the SubX so I cannot say one way or another but lots of people love em though. For supers there are a number of interesting things in the 110 to 125 range that will definitely work. For subs I keep a mag of the maximum expansion on the ready.
