50 yards and in impact is about the same. The 85gr TSX is a great round but it will penetrate further, like the 62gr FedTac, maybe a little more. The 115gr OTM's fragment more where the Pro Hunters seem to fragment a bit less and drive a little deeper. If you go with the TSX then the Pro Hunter isn't necessary since both are considered barrier bullets. I use a 14.7" barrel and the 115gr OTM's are pushing about 2520 average and the 85's averaged a hair over 3000. I also have an 8.5" that I am considering using, but haven't decided if I want to go that route for my job. The Pro Hunters were around 2450 from the 14.7". One of the nice things about using the 6.8 over the .223 is you have a bigger, heavier bullet to push through things like car bodies and windshields. With the .223 you have to be very selective, use a hollow point and it is likely to explode on the windshield, getting little, if any, penetration on the suspect behind. The exception would be the TSX. The problem with the bonded soft points is over penetration, though if you hit center mass most pass throughs will have eaten up most of the bullet's energy. With the 6.8, even the 115gr OTM (which is fancy talk for hollow point boat tail) which fragments heavily in soft tissue will still have enough mass to get through a windshield. Is it optimal? Nope, but there is no free lunch. I lock and load the 85gr TSX's when we are conducting a vehicle assault or on a high risk stop. Otherswise, I stick with the OTM's.
