Befor everone starts thinking that crimping is the cure all for accuracy, it`s not. The real secrete is getting the same bullet pull from every round so that presure remains constant from round to round. If you have a large varation in case neck thickness crimping will definately help even the presure nessary for a constant bullet pull. With the Hornet, in a factroy chamber, and varation in brass this is the most practial way to fix the problem. The problem with the Hornet comes from the fact that they have very thin brass in the case necks, and with the over size chambers of factory rifles it just does not make sence to try to turn the case necks.
If you want to get the best accuracy from your rifle you need to build it from scrach and, amoung other things, have it built with a tight necked chamber. This, of corse, requires that you turn all of your case necks which is a hasle that most shooters don`t want. I, almost never crimp my rifle ammo, and get very good accuracy from most of my rifles. I do not rule out crimping for some of the stubern one though. It is just another tool in the handloader tool box that helps him to get better accuracy than you can with factory ammo from some of those guns that are alittle harder to get the groups we are all after.
