Shooters from GM down to U does not bother me at all...When i go to a match.. i just play... i strategize...if i see something different i usually stick to my gameplan... most of the time if i change on the fly is when i get bogged down.
If a new shooter is next i just quietly get behind someone else while watching...
This is quite interesting as i have used CCI small rifle primers on my glock... my set up is lightning strike striker... with light spring.... so far no ftf's....
I use plastic food containers that fit old ammo boxes... light and cheap ones...plus i dont have to bring the heavy ammo box each time i go to the range...
