It depends on who is talking. I shoot targets with 2 guys who have been handloading/target shooting for many years. If they talk MOA I listen because I know the quality of their rifles and their ability. Any one else....I listen; take it with a grain of salt until they prove that they/their rifle can.
If I put my rifle in a led sled or a similar device, my rifles can shoot MOA. With me behind it.....thats another story
