Tikka T3 30-06

[Kenneth66]

Looking at Tikka web site I noticed their 30-06 barrels are 1/11 twist . Will this be enough change from 1/10 to affect the use of the heavier bullets ?
I like the SGK 180-200 and Berger 175-210 hunting bullets .
Thanks , Kenneth

The 1:11" will handily stabilize BT bullets (.200"x9*) of up to 1.44" long. @ Std sea-level conditions, and 2850 FPS, this wist will produce right at Sg1.5, this should be very good for most .30 Cal. BT bullets of up to 210 Gr. RG

Lol , thank you sir , I'm glad you told me the up to 210 grain part . What does .200"x9* mean ? Thank you for your time ?
Edited to ask about the SG1.5 also .

if you know the bullets dimensions , and approximately the velocity , you could run them in this stability calculator .

BT 0.200" long, with 9 degree angle.

The Sg number posted was calculated using The Tioga Engineering (Bill Davis) Bullet design program - there is none better - JBM is just as reliable. RG

That's a fact.
