FTF on Sig P239 in 357??

[revjross]

I purchased a Sig P239 in 357 this Saturday and shot Federal American Eagles (125 gr) with no problem. I also shot a box of Winchester soft points in a 105 gr (I think) and had a Failure To Feed about every 3rd or 4th round. It looked like it was the ammo. ----- WHAT OTHER 357 SIG AMMO SHOULD I STAY AWAY FROM? ---- IS THE BULK STUFF AT GEORGIA ARMS DEPENDABLE?

Thanks,
Rev ,
