[QUOTE="Coyboy, post: 402439, member: 3733"] The 243 ackley go is about .004" under the 243 go. So it is posible to set the headspace with a 243 GO gauge and proper measuring, the 243 nogo is damm near useless. It is always a nice idea to buy x number of brass from the same lot that you want to fireform. And give it to the smith before he chambers your barrel then he can set up the chamber to give you a slight crush fit on the brass, which is the point of going between '002-.004 under a standard 243 go gauge. I have found that with some brass .004 under is just too much crush and causes excessivly stiff bolt closure. That way if I have the brass I can eliminate any issues the customer may have by making sure everything works as it should. [/QUOTE]
