[QUOTE="ken snyder, post: 523757, member: 26019"] The concerns are feeding and can require modification of the feed ramp, The mouth of the brass likes to catch on the sides of the internal ramp. on stagger feed wells one side will pop out the cartridge to soon and the other side too late. donuts are a very real concern but easily taken care of with an adjustable hand ream. Adjustable reams are available at machinist supply store for under 20 dollars, The adjustable ones give you the option of removing the donut before or after sizing and the same for correcting the problems of moving brass around. reisizing dies can be made with the same ream that cut your chamber but dies made from a casting of your chamber either by your ream guru or custom die manufacturer are better. p.s. take your brass with you while you purchase your reamer and make sure that the pointed pilot end can be filed off short enough that the parrallel section will go past the shoulder neck junction.
