223 – Sierra 69gr. ?

[Bullet]

Could someone with the latest edition of Sierra’s reloading manual tell me what Sierra lists for the accuracy load for 223 - 69gr. Matchkings? Also what load do they list for the same bullet using Varget?

From Sierra Edition V manual:
69 gr. HPBT MatchKing
Cal 223 Remington

Bolt Rifles:
Accuracy load: Viht N540 26.5 gr 3100 fps
Varget start load 19.9 gr @ 2600 fps, max load 26.4 gr @ 3100 fps

AR15 Rifles:
Accuracy load: Varget 25.3 gr 2750 fps
Max Varget load is 26.1 @ 2850 fps

My 2 cents

I have had great results using the Siearra 69gr BTHP Matchking with once fired win Brass and 26.6 grains of BL-C(2) and Federal Magnum primers. Here is a link to a thread I started about the grouping, there's a picture of my best group using this recipe.

I like H380 in my AR. A lot easier to load than Varget and a slight edge in accuracy in my rifle.

What is the twist rate of the barrel you'll be useing these in...it would have to be a 1 in 9 or tighter to stablize this bullet.

I shoot 69gr Siearra out of my Savage 26" 1 in 9 twist bolt action. Does very well.
