[QUOTE="Fiftydriver, post: 483639, member: 10"] 1. Break in barrel first and for most. You can fireform brass while you do this obviously. 2. Load development with formed brass. Does no good to develope a load until you have formed brass and barrel broke in. You do not need to put 100 rounds down the barrel. Just a standard barrel break in will work. 3. Upper level load for a standard 243 Winchester works best. Make sure your chamber has a slight crush fit to the virgin brass when chambered as it should if chambered properly. Do not use any "FIREFORMING" loads, just a standard load using a relatively slower burning powder for the 243 Win. There are thousands of them that will work. No need to seat bullets into the lands if the barrel is set up properly, that does not work well anyway. Just curious why you chose an improved chambering. Seems that you may be a bit new to the wildcat thing. I hope this is for a big game hunting rifle. If its a varmint rifle, you will get really tired of forming brass for a high volume rifle. [/QUOTE]
