Hey all,
Question for the group. End of last season, on the last stage I was faced with the 2 plate spinner with my pistol. Now granted, a lot of the problem was probably my shooting, but, had a devil of a time with it and never did get the thing over. After talking about it with a couple of my squad mates one of the guys revealed that he always keeps a mag full of 147 gr ball nose in the bag for just such an occasion because he felt they hit harder.
Seemed to make sense to me as I was loaded up with nothing but 115 gr round nose for the typical knockdowns and paper that we normally see. However, I also do my own reloading and in the process of digging into the numbers I find that the typical 115 gr ball has more muzzle energy than the 147gr due to the higher velocity. Anywhere from 35-55 ft-lb more depending on the load etc.
Now, I can see the advantages of speed vs mass when it comes to penetration, shooting over longer distances etc. but for steel plates at 7 - 10 yards where penetration isn't an issue and loss of velocity is negligible ( I assume, Is it negligible?) Doesn't it make more sense that the faster 115 gr bullet should impart more energy to the spinner?
When faced with a spinner and a pistol, what do you guys shoot? Should I have a mag full of +P on standby?
I'm shooting an M&P 9 Pro with 5 inch barrel and TTI mag extensions. I was also shooting Freedom Munitions re-loads and I don't know the numbers on those. Maybe the Freedom Munitions 115 gr loads are a little too soft for a spinner?
Thanks in advance.
