ported gas plug

[Faulkner]

Bumping this old thread . . . I'm betting time has shown that the vented gas port has indeed proven it's worth. I've been using one now for several years and it's a simple modification to allow the use of commercial ammo without any issues.

I'm also very curious as to what people do as the vents foul on the vented plugs and the pressures spikes.

No such issue.

That's what I found. I took an Allen and the extra screws if I was working up loads or using new ammo, start big and work down until you get reliable.

I've had a vented gas plug for several years now. Recently I ordered the 'ported' plug from GarandGear. I'm happy with the ported plug. Part of me wants to rig a strain gauge somehow and use my PressureTrace to watch what's happening with the 'ported' vs. vented gas plug in some recent handloads I made with Lapua D-46s over AA-4350, but I don't think I'm going to do that. The data on the GarandGear website addresses enough of a range of factory ammo that I'm not terribly concerned about the rifle with these handloads. I _am_ a bit concerned about my shoulder, as it is not what it was since I hurt it, but that's another matter. :-)

I just picked up one of the GarandGear plugs myself. It seems to do the trick just fine!
