Thread: .223 for the Roar

Well, I have been listening to you guys, so I went back and leaned on my 70 grains loads a little bit. Figuring I cant get enough 2208 in a .223 case to hurt anything too badly, I now have the 70 grainers going 2988fps for a 1.1 inch group.
I figure this is a warmish load. But normal extraction and I can still neck size the cases and use them again. Allowing for the shorter barrel length, it will have to be around the same pressures as the book max.

Sounds like you’re in the ballpark to me. My 6x45 sends a 70gr pill at 2950fps from an 18” barrel. Could go hotter, but not by much, it’s on the ragged edge really….
That’s with H322, a good deal faster powder than 2208. I would have thought that 2206H would be the ticket for heavies in the .223, but I wouldn’t go against @Flyblown on this one.

2206H worked well with the 70 grain Speer but didn’t give me quite as good accuracy as the 2208. But there wasn’t really much in it. I think as usual that’s probably down to the individual rifle than a generalisation. The velocity was pretty much the same as well. At the end of the day I had a 4kg bottle of 2208 ready to go. If I had to load up the next batch with 2206H it wouldn’t be a problem.

@JohnDuxbury how did you get on???? surely you got out and shot SOMETHING.....
