300 Whisper Feed Problem

[cpd23]

Hello all
I have a feed problem with my new ar-15 build. I have read a lot and seems to be a few standard ideas going to fix the issue. Increase the gas port size to match the block. Work with the loads for the gun. Change to a pistol gas port system. I have found info about everything but how to do the pistol gas pot. So what would you suggest to do next. Thanks in advance

open the port you have to.120 and use AA 1680 powder. should function with any of the slower fast powders.

Is this a 16 inch barrel?

Is the port in the carbine or pistol location?

I drilled my gas block with 7/64" bit. Carbine length position, 16" barrel. 11gr of AA1680 is around 1050fps and cycles the action.

Thanks for the info Sami. The load info really helps at least I have one that I know that works.
