The Titanium Nitride (TiN) coating on our neck bushings offers the benefits of smoother sizing and better surface finishes on the outside of your case neck. TiN coating reduces friction and increases the life of the bushing.
To Calculate the bushing size you require, measure the neck diameter of the cartridge where the seated round sits in the neck and take this measurement (Example 0.339") Now subtract 0.002" or 0.003" from this measurement and this will give you a size of a suitable bushing.
0.339 - 0.003 = 0.336"
Another method of calculating neck bushing size can be done by measuring the neck wall thickness of the brass and multiply this by 2 and then add the bullet diameter, once you have this number you can subtract 0.002" or 0.003" to get the bushing size.
Brass wall neck thickness x 2 = 0.029"
Bullet diameter 0.308"
(Example)
0.308" + 0.029" = 0.337" Now subtract 0.003" = 0.334" bushing size
(Please note) some brass cases will become hardened with use a lot more than new or once fired brass and a small amount of spring back can be seen at times in the necks so if you have older brass that's not annealed, we suggest going a slightly tighter bushing.
