223 Rem 1-9 twist

[wvbuckbuster]

With a 1-9 twist what have you found to be the heaviest and or longest bullet to stabilize in this twist? Traded up a 223 with this twist and the heaviest I have on hand and tried is the Sierra 69gr Match King which went straight thru the target no keyhole. Just curious what others have found out through their exsperience.

77 MKs will shoot and the 77 TMKs may shoot as well. Just depends on what side of 9 you’re at the day it was rifled

All 1-9"s are not created equal, you will have to experiment to figure out your barrel. I have had barrels (16" AR) that would put them point on at 100, but never tried them any further out. My CZ 527 Varmint refused to keep them on the same page.

69 grain Custom Competitions, SMKs, and TMKs have done fine. The Nosler accuracy load, 23.5 gr AA2230 has done well in many different rifles. That is a max load.

Too slow a twist doesn't automatically mean it won't shoot, it will reduce BC.

A 1:9 twist can be a bit of a gray area, since stability depends on more than bullet weight alone—bullet length, construction, velocity, and atmospheric conditions all play a role. The fact that your 69-grain MatchKings are showing clean holes is a useful observation, though.

I’d be cautious about assuming that a particular heavier or longer bullet will behave the same way in every rifle. If you want to experiment further, I’d stick with published load data and the bullet/barrel manufacturer’s recommendations rather than relying solely on weight as a guide.

The Berger 70gr VLD is the heaviest I ran thru my 1:9 223 Rem without issues.
