Ive not had any brand of HP jam in Bersa. I say DPX since its all copper their is no jacket that might come of. Will expand better than lead and be more consistent in its expansion. Don't hurt its clocking over 1000FPS from a Bersa Last test I saw was doing 1050 fps as stated on box. The was test by S.A. CAMP well known writer ,gun tester, and member of BT. He was testing the DPX in the Thunder.
Others will say Federal, Remington ,Silvertips, and so on. You must decide and test for relieability in your pistol.
