C Product mags I can do 2.260". Believe it or not I have never rapid fired either of my AR's. Without pushing it I have had no feeding problems and yes possibly greater accuracy with the bullet seated closere to the lands.

OK found load data. None for .204. Ding dang it!

I just found it on Hodgdon's web site. Says available mid January. I'd be really interested to see if it will work well for the .204.

I just got a new sales flyer that listed the new Hornady reloading manual 8th edition. It said it had load data for the new Hodgdon Superformance powder. I assume it's the powder they use in the Hornady Superformance ammo. Anybody here of the release of this powder?

Does anyone know of a lightweight AR barrel in 204? Generally they all seem to be heavy varmint barrels.

The lightest I've seen was on an Remington R15 carbine predator (18"). Does Remington sell these barrels? I would assume they would, but I have not found them to be available.

Well I finally found this post. Thanks FireBallGuy for going out of your way to respond to my inquiry. I really appreciate it. I will look into the magazine issue as that was one of my major concerns. So as long as the Savage Striker 17 Fireball project looks feasable I should start looking for a go...

This is the best deal I've found for a 204 upper.

I have the same ER Shaw barrel that shoots absolutley amazing. 5/8" @ 200yds one hole group @ 100yds with 39gr BlitzKing handloads.

Dang, those are all nice. I'd like to know more about them if you guys would share some details, optics and all.

I dig the monopods. I'm trying to figure out the best way to mount an Accu-Shot monopod on an ARFX skeleton stock.

Can you guys post some pics of your .204 AR's?

I don't have any pics of my custom build yet, but will soon.
I just helped a buddy of mine finish his custom upper as well, and I'll try to get him on here to post some pics to.
