    I got hit with the long range bug. I have stretched my bone stock 17 fireball and Armalite 308 to its limits I believe. I am thinking a custom 243/ 6X47 lapua or variation looking to run the 115's for Michigan whitetail and the rest for steel. I have a Rem 700 SPS 243. Do I just start replacing parts and pay someone to accurize it or do i just get a brand new gun.? I am hoping to either take a class or just learn on my own to stretch to 1000 yards plus. Thanks for your help.

    The 115's with a 243 will run 1k in fine fashion. I would recommend at least a 7.5 twist if you are planning to shoot said bullets.

    What part of Michigan are you from?

    I go to college marquette, but i live in Alpena not too many opportunity for long shots up in the UP. especially with this 10+ inches of snow we got today with the wind that goes with it but back home I deer hunt over a large field.

    Better you than me my friend.:) I guess at this point we are relying on the "warm" water of Lake Michigan to keep us warm and out of snow.

    Agreed. I had a tactical competition rifle built for my small-framed daughter in .243. We used a 1:7.5 Schneider barrel and shoot either 115 DTACs or 105 Scenars and it works VERY well to st least 1,200 yards. Because recoil is light, we were able to make the rifle light and portable and it is quite comfortable for her to carry and handle. It actually comes very close to my 6.5-284 for trajectory, although energy is down with the lighter bullets, and the lighter bullets will blow around just a little more.

    The biggest issue with your SPS, assuming it shoots well enough to effective at extended range, is going to be the (too slow) rifling twist rate of the factory barrel.

    Heavy bullets are needed for best performance at longer distances, and the twist rate needs to be rather fast to fully stabilize them. Even if they don't actually turn sideways, good stability is important to realizing the BC built into the bullet. If the bullet is only marginally stabilized and nutates in flight, the BC is compromised and drag, drop and terminal energy will be much more than expected.

    Even a new rifle is going to need custom work in the form of a fast-twist barrel, so your SPS will likely be a decent basis for having the work done.

    If you're planning to hunt with it as well, you might consider the .260, which delivers about the same trajectory, but more energy at the longer distances by virtue of it's heavier bullets.

    A workable compromise between a good hunting rifle and a good rifle for extreme long range may prove tough to find. First, we have weight and stock styles to consider, and a good prone rifle for long range is going to be a little unwieldy. Then, bullet performance may be an issue, since a hunting rifle with good quality hunting bullets may not deliver the long range performance of the long BTHPs, but those highly efficient BTHPs may not deliver the on-game performance one needs for humane hunting.

    Thanks for help I believe I am just going to have a gun built for me. Do it right the first time with out wasting the money on the SPS and wanting something else later. Hoping to spend under 2 grand with out scope. Then go the Leupold Mark 4 or Nightforce too since I have already sunk money into the gun, the scope isn't a good time to skimp on money.
    How plausible is it to have a 26+ barrel on a Mcmillan A-5 possible mag fed. rifle to and still take it to 1000 plus and staying under that 2 grand bill??

    I've priced it out, and it can be done.....without glass.

    I have a custom built krieger/mcmillan/surgeon/timney 243. I do 1k easy with a 22 IN. 1:8. why do you require such a long barrel? benchrest?

    Also, i wouldn't ditch the sps. you'll need the action. just send it to krieger and they'll fix you up with whatever you want.

    TEX

    better order the stock a month before the barreling job....like today if possible
