230 gr in a 10 twist

I shot 230's for a while in a 3 groove 10 twist Lilja barreled 300 win mag. I got consistent 1 MOA groups without keyholing and saw one mule deer get shot with it and it absolutely hammered it. That was back when Berger had "1-10 minimum" printed on the box. I switched to the 210VLD and 212 ELDx and saw consistently better results which prompted a change.
 
I'm out of town and dont have all my data but my 25" barrel 1/10 twist long range put together 300 Rum seems to like the 230 bergers & Nv570 @ 3036 ft.per.sec. Worked great out to a mile on a milk jug !

I'm actually switching back from a 1:9 twist to a 1:10 for the 230 OTM.

I was previously running the 215 hybrid. Running my actual numbers through the Berger twist calculator, the 230 OTM is actually more stable than running the 215 Hybrid.

Don't fear a little extra twist. I tend to prefer a stability ratio around 1.8. I have over twisted a lot of bullets with excellent accuracy. It also helps them open. For example, my 280ai with 168 vlds is an 8.5 twist. Well over 2 stability factor. It kills elk well and has shot a pile of 3 shot 1.5"s and under at 600yds.
