I'm having a bit of trouble getting my Presidio to cycle a round. I appears that the lifter doesn't lift high enough, and the round is catching on the chamber face. At this time, all I have for bullets are 400gr flat nose that really look like SWC's, (got them from Big Lube) and some 292gr (Blue Falcon). Both type will chamber and the bolt closes nice and tight, the way it's supposed to. I tried making a couple dummy rounds in hopes of getting something to work, so far, zilch. Neither bullet has a crimping groove. This afternoon I am going to make a couple more but with BP loaded but a fired/spent primer to keep from spillage. I don't think its the ammo. It just looks like the lifter isn't lifting high enough. Is there an adjustment for this kind of thing? Getting a little frustrated here.
