[jimpa]

Guy at gun store called me and told of Hornadys e-mail announcement today of 300W ammo in 125 gr and the 208Amax sub sonic. Says it will work in the 300 ACC blaCVKOUT TOO. Musta paid JD for the Wisper logo.

Last Winter Riverguide gifted me 50 pieces of 300 whisper brass he bought from SSK. I believe it was hornady brass. I know its all sporting 125 Nosler BT's now. Nice to know there is another source of loaded ammo besides Corbon.

Check out Silencer Talk. They have a list of about 8 companies coming out with ammo and I think Remington will be behind due to flooding in one of the plants.

lots of "talk" of ammo coming out, I am just getting frustrated with it not "being" out.

220 gr. 300 Blackout by Remington runs great through my Model 1 300 Fireball upper, without a suppressor but with a carbine length spring. They were both very accurate. I've got to test the Corbon again for reliability with the shorter spring. With the stock spring the 220 Corbons didn't quite eject every time. But I think they will now.

You reallly have to just try various ammo if you don't handload. The problem isn't as simple as whether the ammo cycles an AR. The first check is whether the ammo will chamber without pushing the bullet into to case or jamming in the lands. Just being 50 fps faster can cange stable subsonic ammo into unstable (and terribly inaccurate) transonic ammo. Barrel length matters, Chamber, neck, and throat dimensions matter. Case dimensions matter. Seating depth matters, bullet shape matters. Air temperature matters, Air density matters. In some chambers with some ammo velocity dispersion from shot to shot exceeds 50 FPS. There can be several causes. It's not bad ammo or a bad firearm, just a mismatch of designs.

All commercial "Subsonic" 300WTF ammo I've tried works OK in some 300WTF firearms. No ammo 300WTF ammo I've tried works OK in all 300WTF firearms. Just going bang and not blowing up the gun is not all that's necessary to be "OK".

Yeah, a lot of factors for accuacy But my test is just grab one of two factory loads, Make sure they chamber correctly, are reliable, and our able to hit the neck of a deer @ 0-80 yards. Yup, I think she'll work good with my son on the back 40 with a Ruger 77-44 with 300 Gr. XTP max loads.
