Who's making them?
Must be for the new centerfeeds. They have the larger opening.
The staggerfeeds are limited by the magazine opening on the action.
The CDI only seems to come available for Short action.
IS there a long action Detachable set up that can be used to set up for the 338's?
Aldon's right, CDI is short action only.
Nobody else makes a long action DM system for Savage.
That is unless I missed something. I'm a moderator at Savageshooters.com. I'm there quite a bit, but it is possible that I missed something new.
