After this conversation I ran a buffalo bullet .510 all the way through my bore. I measured the marks left behind and I get exactly .500 to the bottom of the grooves. the way I see it that is not a lot of "meat" holding that conical in place waiting to be shot at an elk.
Am I missing something or is that enough friction to hold that .503 no excuses in place over the powder. I have been using wads but I read the NE website and he is saying that wads are not recommended but some guys use them anyway and that a fouled barrel will give the bullet more purchase.
what do you guys think?
