Vmaxpro, if you are getting 3/4" groups at 60 yards you are Golden! That is perfect hunting accuracy! After all your not looking for "target competition" accuracy with these hollow point bullets that were designed for hunting.
I'm glad you decided to lower your velocity...your going to have much better accuracy, especially at longer distances, if you keep them subsonic - below the speed of sound. When your pushing them at 1200 ft./s which is supersonic, there is a point where they bleed off enough energy that they begin to transition from supersonic to subsonic. That is referred to as the transonic zone, and as the bullet slows down and becomes transonic lots of weird things happen to it that just kill its accuracy at that point. One of the main reasons for this is that when supersonic the drag on the bullet is primarily on its nose...but when its subsonic most of the drag is on the base of the bullet. This transition can cause the bullet to wobble, tumble, or spiral out of control...all of which is very bad for accuracy.
For me here by Ft. Lauderdale at Sea Level on an 85 degree day the speed of sound is 1143.8 ft./s. So how do you know what the speed of sound is where you are located? Here is a handy Speed of Sound calculator provided by the National Weather Service. You simply plug in the temperature where you are and it will do the rest for you. The chief factor affecting the speed of sound is the temperature. So here is a link to that calculator for you: https://www.weather.gov/epz/wxcalc_speedofsound
Hope you are happy with the performance of your Hybrids on small game Vmaxpro...I bet this will just anchor them on the spot! Let us know how you do on a real hunt with them please.
All the best to ya, Chuck
