6.5x47 Factory ammo test in bulletin - What bbl length?

[65BR]

I may have missed it....the one Robert Whitley did....how long a barrel was used testing the ammo?

Thanks.

Lapua uses a 660mm or 26inch barrel.

The test I was referring to I thought was one not carried out by Lapua, but by someone testing the factory ammo, not factory test results, but none the less I appreciate the info, further reading on the forums,other than the article on the test results) show some test rifles used by Robert had 31" bbls I believe, so perhaps that was the gun used in tests.??
