Just thought I would put these two tips into one thread.
If the collet supplied with your kinetic hammer fails, you can use the shell holder from your press instead.
If you are a night owl like me, or just don't like the noise, you can use a handheld-anvil to strike the kinetic hammer against. This prevents waking the household as you remove the forty bullets you just put in too deep.
Any solid lump of metal that you can hold in one hand whilst you whack it with your hammer will do. Most of the noise is the bench and floor acting like a guitar sound board.
I also find you can be more precise with the hand-anvil, an advantage if you are just tweaking for COAL rather than removing the bullet entirely.
If anybody is passing and would like a suitable off-cut cube of 40mm mild or stainless they are welcome to call...reasonable prices to most!
Of course any other conventional claw, ball pein or lump hammer will work as well for the anvil…the key for the noise reduction is to hold whatever you are using for the anvil in your hand, rather than resting it on the bench.
