I know some guys who shoot almost daily (mostly range officers) and only at 1300fps, and they are tightwads so they want to save every dime, and don't buy gas checks. I shoot mine about once a month and only 10 or so then cause I take like 4 guns to the range.

I suggest http://www.laser-cast.com/AboutTrueShot.htmlor http://www.beartoothbullets.com/

With beartooth, you can order different diameters if you want to push them hard and both are gas checked.
