Milling an ammo holding block

[Ledd Slinger]

Or perhaps his block is Teflon (PTFE).

I also have some black Delrin (Acetal) I may use for my ammo block. Excellent low friction properties (almost same as Teflon), very easy to machine, and very strong.

It is cutting board material we use at work. It is similar to delrin but not as strong.
Very easy to work with, and I get It free.

HDPE?

Also good material for the task. Nice work

I've made several...out of oak. I used end mill bits, to give me a little room. But, I load the blocks bullet up. Give yourself a little room.

I shoot F-Class, and milled a slot for a timer also. Don't know if that's applicable for you, or not.
