Benchmark reverese taper 2,3 or 6 groove?

[robb frazier]

Of the 3 choices which groove seems to be performing the best. Planning to install 24 to 26 with reverse taper on Hall Action but not certain about Groove. Will shoot Eley Black or Tenex with tuner. Any help would be appreciated.

Robb, I have used 2 groove for several years now and have had a lot of wins. For all weather conditions, I prefer a 16.5 twist.

Gene Davis prepared

I got a Gene Davis prepared Benchmark, two-grove, reverse taper, 16 twist barrel a couple months ago. It really hums. I'd avoid the slow twists as they seem to be very temperature sensitive. Gene prepared a Benchmark two-grove, reverse taper, 17 3/4 inch twist barrel for me earlier. It shoots well when the temperature gets above about 65 degrees, but below 65 degrees it doesn't shoot well at all. Even with the higher temperatures, the 17 3/4" twist barrel doesn't shoot as well as the 16" twist barrel.
