Same stuff. Burned the whole box without a problem. Don't know what to say. Have you had any problems with other JHP rounds? My gun won't chamber Fiocchi FMJ, for example. Same problem you describe. Very weird. Sorry you are having a problem.
I use Corbon DPX as SD and my P380 has no problems with it.
Range ammo is tougher to deal with. I started ordering Winchester, Remington and PMC when I got my 380 in October and I expect to have 6,000+ assorted by mid-Jan and 12,000+ by Feb. Once I'm stocked up I'll just keep ordering 1000 a month.
I fire about 1000 rds a month through my G26 and want to do the same with the P380. I also just ordered a PM9 which should be here this week and I'll do the same through that. The 9mm ammo doesn't seem to be a problem right now and I've stocked up on Remington and WWB. Academy's had decent enough pricing and no shortages.
