Well I just got back from putting another 185rds through the Ultra CDP. It ran well but not perfectly. I ran 100rds of WWB and 85rds of Remington UMC 230gr JHP. It was nearly perfect with the WWB. I believe it had only 1 FTF w/ the WWB. With the UMC it had about 4 FTF's. Towards the end of the session it seemed to loosen up and not hiccup just like the first trip to the range the other day. One strage thing though. I felt it a few times the other day and several times today is that the gun will cycle very slowly. Almost like it's in slow motion. It will still function and ejects the casing and chambers a new round fine. In fact I don't think any of the FTF's were when the gun felt like it was cycling slowly. The gun was clean and lubed. The slide moves freely and smoothly and does not feel like it's hanging up on anything. When I think about it I believe it only does this when shooting the UMC. Could the UMC be a weaker load and cause this? Any ideas?
