[QUOTE="chucknbach, post: 687709, member: 35487"] [FONT=Frutiger-UltraBlack][LEFT]From RCBS instuction manual NECK BUSHING SELECTION[/LEFT] [/FONT][FONT=Arial][SIZE=2][FONT=Arial][SIZE=2][LEFT]Neck bushings are not included. Proper neck bushing size can be determined two ways. Measure the outside neck diameter of a sample loaded cartridge, subtract .002" to .003". This allows approximately .001" of brass spring back for correct neck tension. The other is to measure the neck wall thickness of your case, multiply by two, add the diameter of your bullet and subtract .001". For example: loaded case neck diameter is .333-.002=.331 neck bushing or .012 case neck thickness, .308 diameter bullet is .012+.012+.308 =.332-.001=.331 neck bushing. RCBS suggests that you have neck bushings one to two sizes above and below your target diameter.[/LEFT] [/SIZE][/FONT][/SIZE][/FONT] [/QUOTE]
