I want to re barrel my 300 weatherby mark v and with all the brand of barrels out there im having a tough time deciding what brand to go with. I want accuracy and low heat distortion. Im hoping for input on brands that everybody likes and things like if fluting has helped keep tight groups with a hot barrel. This is all new to me. Thanks

Low heat means bigger contour. I use a fluted Brux #5, .7 muzzle. Next one will be a Bartlein 3B, essentially the same contour.
I don't think fluting helps enough to cool a barrel over the few minutes a guy will wait when at the range, if they even wait that long. I haven't noticed mine cooling down very fast. Guys have good luck with a multitude of brands. Look at bugholes dot com and see what's in stock. Some guys like Pac-Nor too. Long range hunting dot com will have barrel discussions you can read and some of those guys are pretty good at 1000+. There's more to it then a barrel though.

A couple of years ago I rebarreled my custom commercial Mauser (it too is a .300 Wby). I researched barrels and decided on a Shilen match grade SS non fluted barrel. It was a great choice and shoots sub moa out to 500 yds (as far as I want to shoot) with my custom handloads. If you stay with .300 Wby, have a conversation with your 'smith about freebore, as Weatherby uses a lot in their factory rifles. I don't remember the exact amount in mine, but its a lot less than factory.

I'm all ears. I want to redo my Remington 700 7mm my wife bought me when we were dating. New scope, stock, barrel, and trigger update.

One thing to remember....if you buy the best barrel money can buy, and have it installed and set up by a 'smith that is not experienced and does not have the same expertise and workmanship as the barrel.....well you get the picture.

I have a Krieger barrel on my M700 7mm rem mag. I sent my factory barreled action to Krieger and they trued my action and installed the barrel. With this setup, I am able to shoot sub .5 moa groups at 600 yards when the wind is calm, sometimes .3 moa. There are several high quality barrel makers. If you do a comprehensive research, you will see 3-5 makers that are commonly at the top of the list of many of the competitive long range shooters. X2 on the importance of getting a quality gunsmith to do the work. If you want your new rig ready for next hunting season, get your project started pretty soon since barrel wait times can be several months sometimes.

good luck

Thanks for all the input. I think im going to go with a shilen barrel and have asked around about the local gunsmith and everybody speaks highly of him.

Wapita, I saw a great article on fluting and cooling and it has no effect. It was university study.
I've been researching a lot on reloading, barrels, and guns/ammo in general. The amount of info is enormous!
As a newbie, I learn a lot just reading posts on this forum also. Thanks to you and everyone else for their patience with newbie questions! :)

Don't discount a kriger or benchmark. I have both and really like them. Also have a shilen and went with a mcgowen for my savage 6.5-06 build. A #5 contour is a good compromise to good head dispersion and not being pencil thin. A lot of custom smiths like kriger and benchmark accuracy has been top notch in mine as well as ease of cleaning. The shilen copper fouls fairly easily. There are lots of other high quality barrel makers hart PAC-nor and lija to name a few.

Benchmark barrels are some of the best barrels I have used. I shot some matches with the owner of benchmark in Washington and what a great guy. Most of all my custom barrels have been benchmark
 
Look into Lilja for a premium barrel. Never had one that didn't live up to expectations. As far as the more popular barrel suppliers my vote goes to Shilen as I've had good luck with them too. PacNors, well my personal experience with theirs has not been the best. Others may have a different opinion but I had 2 that were problematic. Fluting, many different opinions on doing that. If you already have a good shooting barrel, don't touch it, leave it alone. On a new barrel, well that's up to you. It does shave a little weight off a rifle you'll be carrying which may be a small benefit. Best thing is the "cool" factor. And by that I mean cool looking.

I had my .300 wm re-barreled with a Brux as well as a lot of other work done and the thing is a shooter. A guy out of Idaho named Matt Yore did the work on mine. His company is called Sawtooth Rifles. He just moved his business from Colorado to Idaho because his wife is military. The gun is a shooter and he is a standup guy.
