I got a 9 twist 223 in the safe I need to mess around with more for target work (not hunting), wish it was 8 twist but it isn't. So in looking at higher BC bullets with bang for the buck it seems like the 68gr hornady match offers a good value, its marginally stable at sea level it appears but I'm at 5000+' so it looks like it'd stabilize. Anyone got experience with it in a 9 twist?

Other options that are higher BC that would stabilize: 60gr TMK (not in stock anywhere), 69gr sierra regular match king, 69gr nosler comp, 73gr bergers.

Twist rate can be somewhat of a guideline, not an absolute. Sometimes a barrel that shouldn't shoot a higher bc bullet well does. You might not get the best BC out of it, however it could still shoot accurately. The only way to tell is to try it. In my AR15 I have a 1-9" twist. but I pretty much stayed with the 53gr vmax which has a high BC for it's weight.

I just picked a couple of boxes of these too, and am looking for load data with CFE223 and Varget. For what it’s worth, the label says 1:9 twist on it. I don’t recall ever seeing a twist recommendation on a box of bullets before this.

It doesn’t seem like there’s much love for these bullets. Maybe that’s why they’re priced the way they are.

Correct. Not a TMK fan. They’re less accurate in everything I own. I understand the terminal performance, but I’m mostly banging steel and punching holes in paper with my .223s.
Shot out to 710 this past weekend before a T storm ended my fun. Did have some sporty wind to play in before the bottom fell out.

The Frontier 75 HPBT 5.56 ammo has been really accurate out of my rifles, but it’s hit or miss finding it.

I have an ar with a 9 twist and it shoots the factory AAC 77tmk better than anything.
Any keyholing at extended ranges? My 20" 9 twist 223 shoots 77 SMKs at 100 yards pretty well. But they start keyholing past 350ish yards. 75 BTHP are same story.

I shoot the Hornady 68 BTHPs exclusively in this gun. They don't shoot quite as well as 69 SMKs but they do everything i need to 600 yards and in.

40 round group I shot a few weeks ago for giggles while testing out the 75s I found on the shelf.

Nice group!
Good question on the longer ranges. I’ve shot steel out to 550 and had a decent hit rate. But I haven’t shot paper at long ranges to be sure it’s not keyholing.

I have a Savage with a 1 and 9 twist.
I shoot Sierra 69 grain match Kings, and they shoot like a stinkin laser beam right close to 3000 ft per second. My chronograph is kind of wiggy but I get a lot of 3, 001 and 3005 reading.
23 grains of benchmark with a federal 205 at 2.26 oal. But I got a long tube and it's a bolt gun.

Correction. 65 grain game for 3,000.
69 grain match Kings about 2900. Same powder charge.
