Hey guys, I posted this in the range report branch, but decided to repost here, as I am getting no responses over there. I am trying to make my Kimber Ultra Eclipse II 100% with all kind of ammo. here is the story. Shot it with .21lb spring assembly installed. Those are visibly longer springs comparing to my 18lb (although used) ones. Bad news/good news.. Bad news is that it gave me consistent FTE with +p ammo. I only had Hornady +p 230gr XTP today, otherwise I would try a few different ones. All the FTEs happened on the last round in the mag. Good news is that the gun was free of any problems shooting standard ball ammo (WWB and UMC 230gr). I shot 100 with 21lb springs and then switched to standard 18lb springs for another 150. No issues with any of the spring sets.Got couple of case-into-face though. More with 21lb springs. Hope this is not my hold, but definitely could be one of the reasons for getting the brass fly into forehead...For now I more concerned with FTEs. So how would you guys explain the +p FTE issues? My thinking is that it's probably my extractor not holding the case in place, as with the faster slide cycling with +p ammo the mag did not have enough time to move the follower up to support the empty case which perhaps was too low for ejecting. Also as having a round in the mag did make a difference vs an empty mag, I think that two things helped: 1. the round in the mag was able to support the empty case a bit higher than the empty mag follower would and 2. due to mag's spring compressed more, next round moved up sooner and on-time for supporting the empty case from bellow for it to be ejected. But that's assuming my extractor tension issue. Also, shooting standard ammo I did not get any issues with 18lb springs, although the slide cycle is shorter with 18lb vs. 21lb springs or is it? Any other causes you might think of?
