I bought the FAS 6004 from AoA a while back anticipating my retirement. Now that I've reached that exalted condition I've been spending time with the 6004. The 2 pellets I purchased for it are the RWS R10s and the new H&N Green wadcutters. The R10s work fine but the H&N Greens require seating just a little bit otherwise the pellet will just sit in the breach and not go anywhere. They need to engage the rifling perhaps 1/16 of an inch or so to fire. I've used several small devices but everything I've tried so far pushes the pellet too far into the rifling. I've tried a plastic pencil, a plastic drywall anchor, and a metal pen. All push too far. I'd prefer to use lead free pellets if possible. Any ideas? Thanks in advance.
