Hi all.
I recently picked up a used Kimber 8400 Advanced Tactical in 300 Win Mag. The prior owner had, among other things, a CDI DBM installed. From my research, it looks like CDI was the only company to ever offer a DBM system for the Kimber 8400 SA/LA actions.
I won't be able to shoot the rifle until next week, but sitting at home and hand-cycling ammunition has revealed that the magazines do not sit high enough in relation to the action to reliably feed the rounds. The first 1 or 2 rounds will feed, but rounds 3-5 do not. The bolt starts to push the rounds forward but it overrides the rounds and pushes them back into the magazine after a short distance. If I put upward pressure on the magazine, the feeding issues go away.
The only two options I can think of are:
A - have someone cut the inlet just a little bit higher to allow the entire system to sit closer to the action
or
B - find someone to lengthen the mag catch latch to allow the mags to lock in higher
CDI has been out of business for a long time, and I am unsure if other manufactures use the same latch as the CDI (probably not). Would it be possible to weld on some material to the top of the catch and then file it down to get the magazine to sit at the correct height? I don't know of anyone that does inlet work for the 8400 actions anymore, so option A is probably out.
Or are there other options that I'm not thinking of? I've already tried Magpul Pmags, same problem. I have some Accurate mags on order, as well as a mag lip tool to see if I can spread the lips slightly to allow the round to sit a bit higher, but I'd rather fix the problem instead of having to modify every mag I want to use with the rifle.
Pic of said gun for shits and giggles.
Thanks for any help.
