    Re: How to build a LR gun?

    Hi, I was thinking of the same thing, building a custom rifle or order it but not sure about the barrel thickness and length. Which one will give more accurate at long range? Contour #5,6 or 7, OR increase the barrel length, from 26" to 28"? I was hoping that the rifle will weigh under 10-12lbs. I'll use it for hunting, and maybe participate some local benchrest competition. The caliber would be 300RUM. Any suggestions? Thank you.

    And...............
    I have another question.
    My friend and I were crunching numbers last night, and determined that a 30 cal. 240MK at 3000 FPS is capable of delivering over 1400 FPE at 1500 yards.
    so, do I want a 1 in 10, or a 1 in 9" twist for this rifle?

    Thanks, again.

    JP-

    Sounds like a nice project you have going there, with one exception.

    25 pounds? In a portable hunting rifle? I'd rethink that part. I too like heavy rifles, and have been known to Dremel out & fill the entire fore-end with lead, but only on range/tactical type rifles. My favorite 308 is done that way, but I wouldn't want to think about carrying it very far.

    Other than that, sounds like you should be on your way to a nice rig.

    Re: How to build a LR gun?

    I ordered the rifle yesterday.
    What I ordered was a Savage 116 BSS in .300 RUM. This gun has a laminated stock, with stainless action and a 26" barrel. The savage site says that this weighs 7.75 lbs.I'm assuming that the barrel is in a medium sporter contour to make it that light in weight.
    Does anyone have any idea how much weight will be added by going to a 7, 8, or 9 contour barrel that's 30" long? I'm thinking it would be about 5 lbs.

    Thanks.

    My info on Douglas barrels gives the following info...

    #4 contour (probably about what's on it now), 3 1/2#

    #7 contour, 6 1/4#

    Basic (straight 1.18" tube), 10#

    The #4-7 info is for a 26" tube, the basic is for 27 1/2". You can get a fair idea from this. Going to a 30" tube will pick you up a bit more.

    Re: How to build a LR gun?

    What would you all think of a fluted .900-.950" barrel at 36" without a barrel block. A little longer, about the same weight and just as stiff?

    Would you be inclined to say the added length would still increase leverage on the action in recoil over a shorter possibly even heavyer barrel, thus needing the block? Zero experiance speaking here, just pickin the brains that do.
