Hello Scollins
I'm a Swiss user and i'm a newbie on reloading ammo.
I have a .300whisper-DSC upper with 16"-barrel and gas port position in carbine lenght. I don't know the gas port diameter and the gas tube/gas block are not adjustable. Unfortunately the only currently available .300whisper-ammo in Switzerland is the RUAG Swiss P with 220 grains, but this combination don't cycle on my .300whisper.
You wrote that your cycling subsonic load is 240grains SierraMatchKing with 9.9grains H110.
Do you think this load will cycle on my upper?
Do you mind if i ask you what OAL do you use for this and what kind of crimp?
Do you have any experience with cycling subsonic loads for 7,62x39russian?
I would try N130 due gas port position in the AKM-47, but N130 is not a very fast burning powder and i'm very scary about the danger of secondary explosion that will blow up the gun and cause heavy injury.
Best regards from Switzerland
