We're talking smokeless powder.

Kynoch is the only mfg that i know of offering readily available 600 ammo.

They will cost you $144.00 from Galazans for 5, yes five. That's $30.00 every time you pull the trigger.

Unprimed brass is about $8-$10 per round from Midway (Bertram or A-Square).

Woodleighs will run you about $1.50 to $1.70 (softs & solids) per round.

Set of RCBS dies = $375.00.

Figure you end up with $3K in the gun and buy a set of dies (375) and 50 rounds of brass (500)... your in at roughly $4K and haven't even loaded a round yet.

If you WANT one - then get one, but know that owning and feeding one is not an inespensive proposition.
