Hi all - I hope everyone's having a great weekend. I figured this would be a good question, given the knowledge base we have here, about bullet velocity. My wife and I were talking about this and I realized I had no idea of what the answer could be.
It's my understanding that PCCs are generally, if not mostly, (all maybe?) not allowed at indoor ranges given the increased velocity and added wear on most backstops. Our question is simply this - what's the velocity delta, generally speaking, between a pistol and a PCC? If I used my Glock 19 with Winchester White Box 115gr round, which according to the box puts out around 1190fps, what would the velocity be coming out of my Colt AR-9? Beretta CX4 Storm? What about other calibers - 45ACP, etc.?
What if the barrel was 12, 16, or 20 inches? I'm assuming the law of diminishing returns to a factor would kick in and there would be a point where additional barrel length/more twist would no longer provide increased velocity. Can you mathematically approximate the rate of change over barrel length?
Yes, my wife and I have discussions like this and on a host of other topics. We're two physics/math/other sciences junkies.
Thanks in advance,
