FNG
I use the .503 diameter. That is what NE recommended for knights, and the accuracy was good so I never experimented with anything else. Friction fix, easy to load. I really think the sub bridges take up an gap. I have recovered a few one the far side of elk, they end up with a pronounced dimple from the bridge that has to force the bullet to engage the rifling fully. They are alway 92%+ weight retention and .75 to 1.0in in diameter after going through an elk. Simply awesome.Awesome, thanks for this info. What diameter/size do you order for your 460gn NE?
