Match footage of me using a customized Kel Tec CP33 in a rifle match at Pinetucky Gun Club. Ended up placing 2/39, however I had an unfair advantage :)
For matches I typically use CCI AR Tactical, CCI Mini Mags, or Aguila Super Extra HV CPRN. I don't run into many reliability issues with this gun, the only exception being when I use very inexpensive bulk pack ammo.
