Building a coustom 300 or 338 RUM, need advice.

[Takman]

RidgeRooster, I had a 300Rum built with a 26' Hart barrel in 4 taper with a brake on accurized Rem 700 action and bedded in a Mcmillan Sporter stock . She shoots well out to a 1000 but if I had to do it over I would have done a fluted #6 in the same length and probably a different Mcmillan model(not sure which one). Good luck and have fun.

I have thought about the carbon barrels, but I know very little about them. The gunsmith I usually use (Perfromance Guns) recommended using one to keep the weight down. I do not see very many post about them on LRH, and I am curious why? One concern is chipping the carbon. Can anyone share thier experience with them.
Thanks for all the advice so far.

I guess that I am more concerned with being able to pack the rifle than extreme long range precision. This gun will be built for my first elk hunt, and I am told that I will need to pack it a little ways. A couple guys I work with are hunting with the outfitter that I am planning on using right now, so I will know more when they get back to Kentucky. I would also like to use it around KY for whitetails out to 500 yards max, so what twist should I concider to maybe shoot some 180 grain bullets if I go with the 300 Ultra.
Thanks for the great advice from all of y'all, this is a great forum!

If I was going to settle on the 300 Ultra in a 26" #4 or something I'd get a 1-10 twist, shoot 200 gr Accubonds for everything and be a happy guy. I highly recommend you choose a bullet and practice with it alot and not have multiple loads. If you take a Hart # 4 fluted and a HS sporter stock, your gun will weight 3-4 oz more than the factory 700 but will make you all warm and fuzzy when you shoot it. You might give some thought to selling or trading in your Sendero stock and getting a sporter if you want a packing rifle.
Here is a #4 fluted this rifle is mine in 300 Ultra, weight is under 9 lbs as you see it and it has considerable LR ability

Shawn, bad a## gun. Was that 9# with the scope, I assume it was, you said as you see. RidgeRooster, I sure like shootin ridge to ridge here in the ol' bluegrass state, don't you. I have a Rem 300 Rum and it loves the 220 smk over h-1000. Have shot 5-6 deer 200-500yds, all one shot kills and the SMK performed flawlessly. All kills were bang, flops. DOA The RUM sure prefers the heavy bullets and shoots sub .75 MOA with regularity. Good luck, who and where are you elk hunting with.

Hi as others have said dont use lighter projectiles than 200gr in the 300 RUM you are realy wasting your time. At the long ranges they do not have the eneergy and are effected more with wind drift. The 200gr Accubond or 200go + Sierra MAtchKings are the go and in a 10 twist you may get the 240gr to shoot. I would look at a 9.5 twist so i could shoot everything including the 240gr Sierra and i would start there with bullet selection. I would also use Retumbo as a starting powder as it is fairly stable in all temperature. I would use 1 load only if the 240gr Sierra did not work the 220 surly would then i would only use it as stated above if you switch loads all the time you will never know where your zero's are and you will find it hard to get used to your wind drift.

Thanks, it is under 9 lbs (barely)as you see it with optics. It shoots quite well I hit my 10" disk @ 1148 yards pretty regular with it.
