what bushing for 284 Win

[barnesuser28]

Hey, what size redding bushing do i need for .003 neck tension when using necked up Lapua 6.5x284 brass? I will not be turning the necks.

Thanks, Riley

Both bushings and neck thickness vary a little. Load a dummy round and measure the loaded neck diameter. Try the next larger bushing, first. (i.e.: if the loaded diameter is .313", try a .311" bushing.) Measure the sized neck diameter. If it is Ø.310", you are there. If it is Ø.311", try the next size smaller. If it is Ø.309", go one larger. Pretty simple.
