[QUOTE="bbaley, post: 928438, member: 70360"] Hi all, I just received my new build, with an MCS-DBM Mini Chassis (in a T4A stock) and am having a problem.... The LAST round from the magazine will jamb when closing the bolt SLOW. The first four or three or two chamber fine. even slowly. 95% of the time, the last round will chamber fine when closing bolt fast on last round. I have never seen this before. (but, I am no expert either) on 4 other guns I have had with a magazine. I tested, by: 1) loading 5 rounds (in various order) at least 5 times. same result 2) loading one, of 5 rounds singly in magazine, same result - 50 total cycles. I changed order to make sure it wasn't specific cartridges causing the issue. The test cartridges measure same as Federal Gold match in my Hornaday OAL gauge. Every time, the first 1-4 chamber fine. slow or fast. anyway, I have contacted the gunsmith who built it, he is looking into it but unsure, so I thought I'd check on your experience with this chassis/magazine for similar issues. Last thought - it's only had 10 rounds through it, plus these test cycles... maybe it needs some "wear" ? appreciate any ideas/info/experience ! This is a .308 [/QUOTE]
