Hey guys, I'm new to the forum but have been creepin here for a while. Anyway, I have a FN Slp 18" standard with about 1300 trouble free rounds on it and the only after market thing I've done to it is a nordic components charging handle. Today I took it out to run some rounds through it. I shot 75 rounds of cheap federal field & range 8 shot 3 1/4 dram with out a single issue. However, I tried some fiocchi 00 buck high velocity and all the rounds would eject but now and then I would get a click so I'd check the chamber and it would be empty with the next round sitting on the lfter under the bolt. Yes i did have a firm grip on the weapon with it firmly planted against my shoulder. Any info would be appreciated . On a side note, I did break down the recoil assembly to clean and lube it before this trip for the first time since I've had it.
