Opinions on 20" barrel for .223? (the result is in)

[X146-2]

Wanted to start with Sierra Blitz Kings but none left at the LGS, Noslers should go OK tho I think. Interesting to see what velocity I will get from this barrel using these projies, 2210, ADI cases and CCI BR4 primers??

Looks nice mate - give the 50 or 55gn Sierra Super Roos a run in it, they shoot real well in my Howa 22.250.

I also run the Sierra 50gn Blitzkings in my 222 Howa HB and the are very accurate also.

Also mate if you haven't already done so send the trigger down to the Ebay Guy (Glen Couglan) he's a bloody magican on the Howa Triggers, well worth the $58 which includes return postage!

Shot this 5 shot group using 50gn Nosler Balistic Tips after doing some Scope adjustments after opening up the barrel channel.


5 shot group @ 100m using Nosler Shots 50gn Projectile.

Thanks for the advice guys.
I settled on 25.7 grains of BM2 behind the Noslers for ~3220 fps. Cases are ADI weighed @ around 97 grains.
I can group the Amerian Eagle AR223 ammo at around .6 moa (5 @ 100m). My hand loads were half that but only a 3 shot group.
I'm no dead-eye-dick so I expect the rifle is more capable than me!
can't complain about Howas!

Have a play with the new BM8208 powder as well. Very good velocity, clean burning and accurate! I too rate the 50gr nosler BT's.
