Hey guys, first time posting here. I picked up some 20 cal 55gr Berger’s for a build that I have planned. Does anybody have experience with a 20 xc or a 20x47 lapua? I have talked to a lot of people and yes I understand that barrel life will not be great. I would prefer to go the xc route because I already shoot 6xc and have ample brass. My thought was a 9tw. On another forum people said I should be worrying about blowing the bullet up etc... any thought or comments would be much appreciated.
