I'm starting the search for a barrel for my 25-06, based on the calculators I'm thinking 1:7.5T is the way to go for my elevation and 25-06 velocities if I want to shoot the 130 class bullets. I'm torn bc I'm thinking that twist will be too fast for just about everything else so I'd likely be locked in to just a few options. I think 1:9 will be too slow, even 1:8 doesn't seem like a sure thing at my elevation and hunting temps, or I wouldn't hesitate to go that route. 7.5T is generating a lot of RPM's at 25-06 velocities, so makes me a bit nervous unless I'm sold on sticking with the 130's for this gun. Either way, it's awesome that Berger is making this and the 135 gr option and I would like to have them as an option in my '06.
