Just a heads up to any and all (mm shooters out there. If you have purchased the big white box-o-Winchester, 100ct. and your once reliable firearm is not so reliable it's the ammo.Two years of watching good guns fail to operate on this inferior ammo is too many. Plain truth the crap is under-powered and most European service grade pistols (H+K, Sig, Browning HP..etc) need full power loads to function at peak.There is no way Win. can put the same components in a $12 box of 100 rds that they put in a $10 box of 50. Rumor has it the ammo is being produced in Europe and the manuf. knows that the product is inferior and is keeping quiet about their relation to it. The problem seems to be only with the big boxes. The 50 ct, boxes seem fine.
