I did a search, but. if you don't know what your looking for its realy hard to find it.
i am trying to understand gas checks? i know they are made of copper. i know it helps reduce fouling. can it help a soft bullet go out the barrel? with a gas check does the bullet need to have a high brinn test? lets say if all things were equal except the bullet hardness and you were shoot oh say a realy thick skinned huge hog. what would be the difference between a gas checked bullet and one that wasn't?
lee says something like: a bullet has to be so hard to go so fast. they even give the speed to match the hardness.
PLEASE any and all info would be great!
i want to learn as much as i can about them
THANK YOU VERY MUCH
