Quoted:

You can buy and shoot any ammo you want. No specifics unless you detail some.



If you want to just bust rock, get any M33 ball out there.



If you want to start a fire, any tracer will do. Even APIT.



Want to have some fun with penetrating steel? Get AP, API or APIT.

On the tracer rounds or any assorted mix containing a tracer mixture, have a firehose handy.



If you want a highly accurate round for long distances, buy ammo with the Hornady 750 gr. A-Max projectile in it.

You now have a few places to start from. Congrats are in order for your new toy. That is a nice piece and have fired one myself.

Sucker is heavy.



If you really want to try and see if you can get better results than factory ammo, might look into reloading for your piece.



Initial outlay is gonna "sting" a little but after that, the possibilities are endless.
