I have recently done some maintenance on my SDB and I replaced the white plastic guide rails that the main body moves on as one was cracked and another was on its way. The press now feels very tight as I pull the lever. Will this wear in?? I am assuming so since its plastic but I don't want to cause any undue strain on the machine.

Otherwise it seems to load fine, everything cycles/feeds correctly etc.

Also separate to maintenance, is there ever a plan for a shell feeder & bullet feeder for the SDB?? or is it just not mechanically viable or something? I love my machine and only reload pistol but I do reload something like 20-30,000 rounds a year or possibly more (ive kinda lost count)

Thanks,

John.
