[QUOTE="Okanogan, post: 1912025, member: 90397"] I suspect you may be correct that approaching the problem from the ID with a mandrel will make mute whether or not slightly different bullet diameters seat correctly or not. If I understand it correctly, to make sure it always works out the die will originally undersize the neck slightly and the expander mandrel will slightly undersize the ID to make sure everything snugs up nicely. I'm assuming the trade off is it slightly over works the brass in the neck. I'm not disagreeing with your suggestion but I already have the Redding bushing S die and the rifle/ reloads seem to be shooting fairly well. As long as it continues to shoot well, I think I can achieve the same thing with a slightly undersized bushing -either a .290 or .289. If the Bryan Litz Applied Ballistics Vol 2 was right, I'm not giving up much if anything by varying neck tension as long as the all my bullet selection seat correctly. My original intent with the post was to see if others had noticed variation in bushing selection requirement based on their bullet selection. It would seem the answer by omission is no. In my case, it seems that only part of the answer is the bullet selection itself so the remainder has to be in my set up/ components, with the most likely contributor being the ADG brass. For what it is worth, I did run a expander mandrel through the virgin brass before resizing it but of course that will not change the varying neck tension that might occur for a number of reasons when using a bushing.
