My department recently switched from normal ammo Remington slugs and Federal reduced buck shot. To Hornady TAP buckshot and CHOKE "precision round" as a slug replacement.  The only problem is our qualification/pratice was two rounds each and we only get issued 4 buck and 2 "precision".  I'm having a hard time finding my own supply and my old ammo is now a policy violation to have in my car.  Any sources for ammo.  

You want to call Hornady and talk with Kathy McHale who handles LE sales.

They'll pay shipping.  Order needs to be on a P.O. or Agency Letterhead.  You can pay with a credit card or they'll bill the agency.

Not familiar with that particular slug load but if you should have a rifled barrel, get several boxes of the H2K slug to try.  

It's a 300 or 350 grain 45 xtp in a sabot with a muzzle velocity of 1970 or somewhere close to that.  

If I concentrate, it will group 2 to 3 inches at 200 (two) yards.
I've taken deer at 200, 175, 150 yards and the farthest any traveled was about 30 feet.
