30BR barrel suggestions?

[mike mccormick]

I have in mind to build a walking around rifle in 30br. I have a R700 single shot action. Would be using 115-135 grain bullets. The question is, what barrel profile? I have been told I don't need over a 22 inch barrel. What profile would give me .700-.750" at the muzzle? Would I stick to the 17 twist, or go to a faster twist?

The sendero taper is close to that but with a walk-around-rifle you may want a little lighter taper. I think you are correct with length and the 1 - 17 twist will work for you as I'm shooting the 125 gr. and stabilizing great with mine. My barrel is 24 inch Lilja and is a bench rifle as well built by ODCR (WSMNUT) here on the site.

Check out the Bartlein 3b contour. .700” at the muzzle on a standard blank and by the time you cut it back to 22” it’ll be somewhere between .700”-.750”.

I have a 17 twist Lilja #5, I think. At 16.1” it’s awesome. I walk around with it, suppressed. You don’t lose that much velocity going shorter with the 30BR. I can get 2,900 with a BIB 118 & 2,850 with a 125 TNT. I wouldn’t want it any longer.

Bartlien bull sporter is .750 at the muzzle if you want a sporter taper. A hunter benchrest is straight taper and .750 I believe.

30BR Repeater in 700SA Footprint

I got my new scope on it an headed out on Saturday. What a difference good glass makes! First, I got it printing 2" high at 100 yards, which is about a 225 yard zero with the 125 SST @ 2,860. Then, at 409 yards I just held the 2nd hash mark in the JM-1 reticle (which is supposed to be 400...

Two of my best friends did their hunting this year with 30 BR’s using the 110 grn Barnes TSX out of1-17 twist barrels at 3000 FPS. Both bagged nice White Tails. The recovered bullets opened to about 5/8 inch.

This is East Texas hunting we’re most shots are between 100 and 200 yards.
As for barrel length, 22 inches is about perfect. If you get a Remington Varmint Taper, you will have a good weight profile at 22 inches.
