Gunsmithing Longer Mags for a .338LM?

[SavageLapua]

I'm planning on ordering a Manners T4A for my Savage 110BA. I run Berger 300's that are seated too long for the magazine... I was just wondering if there is an out fit out there that builds a magazine with an internal length of 4".

Seekins is your best bet. Mine feeds flawlessly. I think max OAL is around 3.93".

Excellent, Thanks.

Does the Seekins DBM inletting mimic any other DBM, like Badger Ordnance? Or is it another animal all together?
