I'm just curious if these is much of an accuracy difference between a custom fitted and a drop-in savage barrel? I was reading that Barlein barrels won't make drop-ins because of the tolerances in the threads of the barrels. Would slightly loose threads add any play in the system or is there another locking mechanism involved? I don't own a savage, yet, but will in a couple days.

I was originally going to go with a drop-in, but now I'm thinking I might order a blank and have a barrel custom fitted. This will be for F class competitions.
