[QUOTE="BountyHunter, post: 1004193, member: 12"] You are eventually going to have to FL size a 7mm Mag unless you reload to 7mm Mauser velocities. However, you can buy a Forester bump die which does not size the body if you want to try it. IMO you would be much better off buying a Redding body bump die ($28) and sending it with some fired cases to Jim Carstenson (JLC Precision) and having him make you a custom honed FL neck bushing die ($80) and be done with it. It fits your chamber perfectly, minimal sizing but avoids the click you get when you shoot full power loads without resizing or you are way overpressure. Brass is not overworked and lasts a long time when you use the correct sized FL die set up correctly. One of the big reasons the NS only crowd keeps hollering is the "trimming" due to the expander balls pulling the necks. Jims die does not use an expander ball. As for neck turning being needed, couple points. 1. In most factory chambers waste of time and money unless your brass is way off dimension on one side or wide variances. Simply buy a neck micrometer to measure and see if even needed. Plus now that puts you into using neck bushing dies IF you have not been in order to maintain bullet tension. Not saying that is bad, just another cost and absolutely not be required if shooting .5 MOA 2. Buy quality brass: RWS, Lapua are my first two choices. 3. Get the Sinclair international shooting supplies catalog and look at their websites, they have several videos on tons of reloading subjects. Get Youtube also. 4. If your gun is shooting .5 MOA it will not change due to you "not neck turning". DO NOT MESS WITH WHAT YOU ARE DOING!!!!! [/QUOTE]
