Suppressors GAP built 338 "whisper"

[762frmafr]

Well the final piece to my 338 Whisper project came in today. The 5/8-24 to 3-lug adapter. Now I can run my YHM 9mm 3-lug SMG suppressor on my 338 whisper. Specs on the rifle are as follows:

Remington 700 action with side bolt release
6.5 twist bartlein barrel 16" long chambered in 338 Federal
Badger bottom metal
McMillan A-5 stock
NF 20 MOA base

All parts screwed together by Flounder at GAP. 300 grain SMK's at 1050 with Trailboss. This thing should be literally whisper quiet.

Will post video as soon as I settle on a projectile for hunting. If anyone has any suggestions I am all ears.

Re: GAP built 338 "whisper"

How is the case capacity when loaded? is there a lot of "free" space for the powder? I bet that 300SMK takes up a lot of room in the case. My 300 whisper is more consistant with the 220s and 240s to take up some of the extra room in the case. That is a sweet rig videos please

Re: GAP built 338 "whisper"

Is that "step" in the barrel aft of the 3-lug mount part of the mount?

Yes...reason being is because it is a "step down" adapter. 5/8-24 to 3-lug where is is typically 1/2-28 to 3-lug.

Done did that....he only confirmed what I was thinking. I have 100 Lehigh Subsonic projectiles on their way. http://www.lehighbullets.com/proddetail.asp?prod=338-501

Re: GAP built 338 "whisper"

Lehigh is a great group. Saw them at SHOT last year and they were explaining their 95BMG. The projectile weights almost a pound! The muzzle brake the on the rifle was 30 pounds alone.

Pretty crazy shit!

That is a really nice whisper! By the way, you're out of TP.

Re: GAP built 338 "whisper"

Would also like to see a video and hear what kind of range you are getting.

Re: GAP built 338 "whisper"

I will be posting video once I have my loads worked out. I just received 100 300 grain Scenars and 100 Lehigh subsonic projectiles that I stuffed with 20 grain 17 caliber payload bullets. In the following pic the subsonic projectiles are flanked by the Scenars.

Re: GAP built 338 "whisper"

THIS is what the Lehigh's look like when they expand.

Re: GAP built 338 "whisper"

Wow, that's so Nasty! That may have to be my next build.

Re: GAP built 338 "whisper"

so what was the inspiration of stuffing the lehigh's? I am very interested in building a subsonic suppressed rifle now!

Re: GAP built 338 "whisper"

nevermind, I just visited lehighs website. that's just innovative.
