Manners MCS-DBM Mini Chassis problem
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
