Redding bushing dies???

[stevietangles]

Hey guys,
i just purchased a bushing die set from redding and was wondering what tension you use for the bushing.

im loading a 243
lapua brass

ive sized and loaded a couple and have a very consistent outside neck diameter of .271"

i have read that i should start with a neck tension of -.002" but the problem is the local shop only has .268" which is .003" neck tension, would the one thou really impact accuracy, build more pressure...

what do you guys typically use for neck tension when buying a bushing for your dies?

the firearm will be magazine fed so i cannot have the bullets to loose.

thanks

I prefer .003".

For my target guns that get single fed I use 2 thou. But for hunting gear 3 thou is the norm. Little extra security when mag fed

I usually end up at 003 also. Seems to be best for a few calibers I have bushing dies for.

thanks for the input.

thanks for your replies ill go with the three thou.

I found 3 thou more accurate than 2 thou.

Brass usually springs back around 0.001". Get yourself a set of gauge pins. These will accurately tell you what the ID is after sizing.
