280 ai build barrel contour selection

[MT257]

So I have a Winchester 770 that I am going to use as a donor action to build a 280ai. It started as a 30-06. I am in the process of looking for barrels. I have in the past used PacNor. I was just wondering what everyone thought the best contour would be for this build - lightweight, #1 or #2? How about barrel length? The primary use for this will be deer and elk. TIA

I would do a #2 at 24".

Used a Bartlein #3 @ 24" + brake for my son's 280 a.i. Shoots very good out to 600 yds, the farthest he's shot it.

You can flute a #3 to get very close to #2 weight and seems to shoot better at longer ranges.
Just my opinion.

 

[JMW67]

If it were my decision I would use a number 3 at 24 min. and make up the weight on the stock and optics

 

[MT257]

Would the flutes have any effect other than weight savings? Would it be smart to go the #3 with and pay extra for fluting or just get a standard #2?

Fluted Bartlein 3B at 26". Let the big dog eat. You won't notice the extra two inches:

I have a Bartlein #3 finished at 26" and it's heavier than I anticipated. I would lean towards a #2 or #2B or a fluted #3 if I was to do it again for a lighter weight hunting rifle. The #3 and #3B are best for an all around rifle or a dedicated long range rifle that's mid weight. That's just my opinion.

2b

I'd go brux #3 or #4. That's equivalent to Bart 2b or 3. Brux makes great barrels. Wish someone would carbon wrap em. I honestly think Helix6 uses their blanks but they won't tell a soul.

http://www.bugholes.com/product-p/b-7mm-9tw-ss-n4-28.htm here's one in stock. They have #3 and #4 8 and 9tw available.

I agree with the Brux #3. Got one on my 300 win Mag, and it's great. Actually I'm happy with all my Brux barrels. I thought Helix6 made their own blanks? Just put one on my 25-284. Still in load development but it's shooting really good with basically no copper fouling during break in.

I definitely agree with highdrum and Jud. A 3b is a pig. I had a 280ackley with a 3 bartlien at 24, it was a little bit more than I liked when finished. 2b are about perfect with mcmillan edge stocks and heavier scopes for my personal balance preferences.

 

[MT257]

Do Brux barrels projected weight on their barrels found on their web page run pretty accurate?

What bullets and velocity were you getting from you 24"?

Bartlien 2b if unfluted Or #3 if fluted, Or an equivalent Brux contour barrel. Enough weight to balance a rig out and hold steady. I have a Lilja #4 fluted on my rig @ 25 inches with a McMillan edge fill classic stock and Leupold VX6HD. Weight is 9lbs evan.
