I am getting ready to send my .30-06 rifle off to be rebarreled to a .25-06. I plan on using 110 - 120 grain bullets, and I was wondering if anyone had input on the following questions:

1) What barrel length would you recommend? I was planning on going with a 23" or 24" barrel.

2) What twist would you recommend?

3) There are options for 3,4,5 or 6 groove barrels. Not really sure what that means. Which would be the best of these?

Thanks for your help!

Fine....I like 22" but those lengths are good too.

if you have a four headed coin flip it....I'm not sure there's a tinker's damn bit of differece at all.

The .25-06 is a marvelous combo gun for deer, pronghorns and varmints.....have a ball.

Being an "overbore" cartridge, the 25-06 needs at least a 24" tube to develop good velocity IMHO. Your mileage may vary.

Glen, can you explain about how much velocity loss a .25-06 will have with a 22" compared to a 24" barrel?

1) Given the 25-06's expansion ratio I'd go with a 24" unless you're trying to make an ultralight, in which case I'd go 22.5" or 23".
You'd be giving up a bit of velocity and gaining abit of muzzle blast, but not enough to make a difference in the field.

2) 1-10"

3) 3 groove allegedly wear better, though I judge by your statement of 110-120 grain bullets that this will be a deer/antelop rifle, and not a varmint rifle. Thus, I suspect this is not going to make much of a difference for you in a hunting rifle.

Thanks for the replies!
