223 with Hornady 68 BTHP

[KnotRight]

Trying to play around with a couple 223s. One is a CZ 527 (1:9) and the other is a 18" AR that I built (1:8). With a few 68 grn that I have loaded, I have not found a rifle that likes them. Going to play around with some CFE223 and Varget. Was using 748 powder. Trying to reach out to 500 yards. I have no problem with the 18" gun and 55 grn FMJ to hit steel at 4-500 yards..

I cooked up several loads using the same bullets and TAC powder and couldn't maintain 1 MOA to save my life. My 1:8 rifles have done much better with 60-65gr bullets. Pushing them out past 400 I see why you would want the heavies but I think you're going to need SMKs to get better performance in that weight.

I got a good price on the Hornady's a few years ago but wish I had spent the extra pennies on Sierra's.

The factory loads of SMK and Hornady Match shoot great out of my rifles.
I can't replicate that with any powder and primer combo I've imagined.
I gave up. Now I use Sierra Game Kings for anything over 300 yds in my .223 loads.

Me too. 68gr BTHP Siera GK with H335 powder. CCI primers.

Harsh reality is that those bullets might not like that gun no matter the powder, primer and/or brass!

Varget in 223 with heavier bullets is great. It doesn't meter well in a progressive press. Imr8208xbr is solid for running on a progressive.

I second hornady match. Tight groups. For a 1:8 64-68 grain worked well in my ar’s.
