    I've had my 300 for 15 years now and it is in need of a makeover! Its a Remington 700 sporter weight barrel with a well used wood stock. So heres my build list for my 300 win mag pack hunting rifle. I want to keep the weight down as I do a lot of backpack hunting. Is the cost for a CF barrel worth it? Tell me what you guys think.

    Mcmillin A-3 sporter stock

    Lilja 28" 1:9 #5 barrel or Proof 28" 1:9

    already has a calvin elite trigger

    I seen yesterday that carbonsix is having a sale on there cf barrels. $755 for a chambered and threaded barrel. I don't know the quality of them but I thought that price was pretty good. For another 80 they will install it or for 165 I think they will true your 700 action and install the barrel. No personal experience with CF barrels so I don't know for sure. To save weight though it seems like a no brainer if you got the cash.

    If you're serious about saving weight, ditch the 28" barrel idea . C.f. is great if you can afford it, barrel and stock . My 24" 300 WM smashes critters with authority, 215 Hybrids at 2800 fps .

    Oh I know 24" tube would work but I have always felt like 26" is the min in a magnum. but maybe i'll drop it to 26...

    I have both steel and CF. I don't see that much of a weight benefit in the CF over the steel in relation to the more expensive CF. if you want less weight, then flute the heck out of the steel barrel and it will probably only be a few ounces heavier depending on contour than the CF. Also, 26 or 28 will give you better velocity and stability than a 24. Keep in mind, too light weight of a rifle is much more difficult to shoot accurately than say one a couple of pounds more. Good luck on your venture.

    I have Lilja barrels, 30" in .277 cal 1:8" and 27" in .30 cal 1:9", both are 3-grooves and #6 contour and loving it thus far.

    I don't think you can go wrong with either one, both are Made in Montana products. :cool:

    I have a Proof CF and steel barrels. If you make this barrel last another 15 years I'd say the CF is worth it. It will look a lot better sitting in that A-3 than a skinny steel barrel. The slight weight savings will help your rifle balance out a little better with a 28" Bbl, especially if you go the carbon fill A-3. Although I would prefer a 26" max but nothing wrong with a 28. In a hunting scenario the carbon barrel will not give an accuracy advantage and not enough of a weight savings advantage compared to a 4-5 contour worth mentioning. In my eyes it just comes down to looks and budget. If your going to make this barrel last as long as the first one then go for the CF barrel for the extra $350-400. If your going to shoot it all year and hunt with it then have to replace the barrel in 1-2 years maybe your better off with the steel barrel. Either will perform great, one just looks cooler. :D

    I'm building a 338 edge and ordered a CF barrel. Saving over 1# for comparable barrel rigidity is a big deal. Highly doubt you'll ever wish the gun weighed more, especially if elk in high elevation is on the list.
    Went with a 26" barrel due to the handiness. I'll give a little velocity for ease of use. If you add a brake, that adds a couple inches too.
