wiring?
 

I have some REAL milspec wiring in 18awg and 14awg silver plated with thin wall ptfe casing available to me.
The 14awg is thin enough that it looks like it would fit fine.
Is this overkill? Is the 18awg too thin?

18-20 is what classic army used to wire their guns with back in the day.
18awg is fine for most guns, especially when using high quality silver coated copper.
14awg is good if you're in the 20-30A draw range or obsessive about battery efficiency.

Obsessive is me.
