Re: A few reloading questions
I neck turn both my 243 and my 300WSM for about 2/3rds to 3/4s clean up in my factory rifles, in fact i benchrest prep all my cases. This gives me absolute confidance that i have loaded the best ammo that i possibly can.
Anyway back to your question, you need to size your necks first, because they then have to be expanded up to fit your neck turner mandrel, this is done with a seperate expander mandrel which is usually sized slightly smaller to allow for brass springback and a snug fit on the neck turning mandrel. I use K&M products tools but equally good quality tools are available from Sinclair.
You are now ready to neck turn,take it easy and remove small amounts of material at time untill you get your desired clean up. With the K&M you can power your case holder with an electric screwdriver.
After you have neck turned,seat a bullet, Your "S type" dies are ideal,because you now have to select a bushing of the correct size which is about .003" smaller then the diametre of your turned neck with a seated bullet. Once this is done you are ready to go.
Its a time consuming process, but i think all of these accuracy enhancing procedures are well worth it. Others will tell there's no point in a factory barrel, remember this if you miss, you cant blame your ammo [img]/ubbthreads/images/graemlins/wink.gif[/img] [img]/ubbthreads/images/graemlins/wink.gif[/img]
