Simply, I had a 338-06AI version built using the venerable 700 action. I then had a 24in Gaillard barrel mated to the action. The twist I believe is 1-10. The action is trued and bedded.
The load I've settled on uses a 210gr Scirocco on top of 61.0gr RL-17. This chrono's 2850 and groups under an in. Great ballistics.
Glad I had the gun made. It compliments my 270 well.
In total I have about $1200 into the gun before optics. It helps to be good friends with the gunsmith otherwise you can add some green to that dollar amount.
Good luck with your project.
