TPM charging accessories are machined on high-performance CNC lathes. ensuring very tight tolerances and exceptional surface finishes.
Made of steel and treated with Chrome Molybdenum to guarantee very high hardness.
To maintain excellent concentricity, accessories are not heat treated after machining.
The Bushings are inserted inside the Full and Neck dies with the aim of giving the case collar a correct shape (in terms of diameter).
Small reminder on choosing your bushing.
Measures the diameter of the neck of a cartridge complete with mounted ball.
Subtract 0.002 to 0.003 from this inch value and you will get the value of the bushing to use.
For example, neck diameter with mounted bullet 8.53 mm (divided by 25.4 to get it in inches), or 0.336.
At this value, we remove 0.003
0.336 – 0.003 = 0.333. The bushing to use is 0.333.
