Has anyone built a 6.5 Roberts AI lately? I put one together and still hunting for a good load.Thanks, Joe

Close...just a touch longer case.....6.5x55 AI.

What is your case capacity?

What bullet(s) have you tried?

Chronograph any of the loads?

Barrel length? Twist rate?

Several of the manuals list 6.5x57 data - I know the shoulder is farther forward on the 6.5x57 than on the 257 Roberts or 7x57 so it has more capacity. Don't imagine it has as much as the AI version of the 6.5 Roberts but that should be a decent place to start.

I think Sierra and Hornady list the 6.5x57 - maybe others too.
