Not a core-lokt fan, I've seen the misfires. Loaded up with Federal Fusions and the gun never had another issue. Do what you want, but I DO NOT trust them.
seems like I remember Remington had some component issues back around 2004-2005 but they got it straightened out pretty quickly. havent heard of anyone having issues in a long time and I frequent a lot of gun boards.
are these misfire issues you guys had more recent?
