<P style="MARGIN: 0px">I just finished my first round of sporting clays with the Baikal MP153, and, except for one failure to eject with an overly long Rem. 3.5" case during pattern testing, there has not been 1 hiccup of any kind regardless of shell length or type in over 450 rounds through the gun.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">I examined the one shell that failed to eject. It was extracted from the chamber, but lay in the action. It was obvious that the shell was long for the ejection port, but I had to measure it. It was 3.495" long, just .005" short of a full 3.5". There were some other cases which ejected, but fell relatively close to me as I was shooting, compared to the other cases ejected, so I measured them, too. They were all close to a full 3.5" long.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">I had a number of cases I had purchased from Precision Reloading, and a couple of hundred given to me by Big Mexican after his goose hunting trip to Canada last Fall. So, I measured several of each variety.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">The Remington's had three basic lengths: 3.350" which were #6 lead turkey load cases, 3.490" which caused the ejection problems, and 3.430" which composed the majority.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">Winchesters were composed of: 3.430" Supremes, 3.440" Xpert HV, and Drylocks which varied from 3.450" to 3.490.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">Kents were averaging 3.380".</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">The cases would vary plus or minus .010" within each grouping, but were fairly consistent otherwise.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">When the 3.5" Mossy 835 first came on the market back in the early '90's, the two guys with whom I hunted each had one. They had ejection problems with every 3.5" shell except the Federals. The Federals were the same length as the Win. and Rem. cases, but the plastic in the mouth of the case was softer and often shredded, allowing more reliable ejection.</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">I made a trim die and am trimming all my Rem. 3.5" cases to the more common and trouble free length of 3.430".</P> <P style="MARGIN: 0px"> </P> <P style="MARGIN: 0px">So, if you're having ejection problems with your 3.5" gun, where the shell is extracted from the chamber, but is not ejected from the gun, if the ejector is working properly, consider switching to a shorter shell. It just might cure your problem.</P>
