i'm trying to find a way to set myself up with a reasonable number of .303 drill rounds.
in Australia.303 snap caps are around $18-20 a pair, as i want 30 plus they are simply too expensive for me.
i'm thinking of using some old brass (drilled to differentiate from live rounds) with projectiles crimped in, and a polyurethane plug in place of the primer to take the shock out of the firing pin.
berden .303 primers are .250" and polyurethane rod is available in 1/4".
will urethane rod with a shore hardness of 95A be about right to take the shock out of the pin while still surviving repeated strikes?
the choice of urethane was a guess based on it's use for suspension bushes (repeated hard shocks without permanent deformation), is it the right materiel?
thanks
