7mm STW Reloading Thread

Well, we have our own STW section now, we might as well start our own 7mm STW reloading thread.

Let's see what favorites are out there.

Please include what firearm you are using, including barrel type , length and twist.
Also include info for brass, bullets, primers, powder, charge weights, OAL, etc.
If you have a chrono, let use know the speeds you are getting.

Don't forget, anyone reading this, hand loading can be dangerous if done improperly.
Please view loads listed and a guideline and treat any load you find listed as if it is too hot for your rifle, and safely build up loads for your own firearm.
**Just because someone is using the same firearm you are, does not automatically make their loads safe for your firearm**

Be safe!

    Good job Fire! This thread type hadn't crossed my mind for some reason. Glad it did cross yours.

    Gun: Remington 700 Sendero SF 7mmSTW, 26" barrel, 9.25" twist
    Scope: Zeiss Conquest 6.5-20x50

    Current favorite is:

    Berger VLD 180gr bullets
    75.5gr H1000
    Federal Premium brass
    Federal 215 primers

    Seated to 3.858" C.O.L. (Which, as we all know varies from gun to gun ).

    No chrono, yet....However, the Berger manual says I should be right around 2,775 fps.

    Re: 7mm STW Reloading Thread

    Boy, since the STW first came out, some awesome powders have came down the pike, and for the longest time, I was a die hard RL22 user, and swore by it, even if it is temp sensitive. The H1000 has always been good, but when the RL 25 came on, that changed everything for me, except in one gun. My standard load is now,


    82.0-rl25-145LRX
    215 GM primer
    A Square brass
    COAL is 3.688. ( Remington Action )
    Coal is 3.640 . ( Winchester Action )
    1-9.5 twist
    3440 fps

    79.3 - RL22-140ct
    215 GM primer
    Winchester brass
    Coal - 3.675
    1-9.5 twist
    3389 fps

    81.5-RL25-140 partition
    Winchester brass
    215 GM primer
    3.640 COAL
    1-9 twist
    3377 FPS

    The formulas work for me, but were worked up to, not just assumed.

    Shooting a 24" bbl lh rem 700 with a (unknown brand) custom pipe on it
    don't know the twist; don't care.. the pills spin just fine

    using:
    140 nos a-bond
    82.0 grains rl25
    win brass
    215
    seated to 3.650" oal.
    My 26" bbl sendero was 3450 fps with this; I haven't bothered to chrono this rifle. I may eventually chrono it but a 100 fps loss (I expect less) for the shorter bbl still puts me at 150 fps over a 7 rem so what do I care?
    I am still working with other loads but looking back at the records and re-proving lately has proven this to be the only combo in this rifle to be consistantly accurate assuming the rifle to be 100%. The rifle has has had a few minor problems but is pretty bulletproof now.

    Savage 112 Factory 7STW 26' Factory tube 9.5 inch twist.

    Remington Brass
    CCI 250 Large Magnum Rifle Primers
    82 Grns. H-1000
    140 Grn Accu-bond
    3290 FPS MV

    Remington Brass
    CCI 250 Large Magnum Rifle Primers
    82 Grns. H-1000
    140 Grn. Berger Hunting VLD
    3300 FPS MV


    Both shoot at basically same POI

    I usually load a Berger in the tube since are loaded out past the magazine box length and put a couple of Accu-bonds in the mag box just in case I ever would need a quick follow up shot. Funny I have never had to have a follow up shot with the STW.

    Re: 7mm STW Reloading Thread

    Winchester 70 Classic Sporter 26" factory Barrel
    Ziess Conquest 4.5X14X 50mm

    Winchester Brass
    140 grain Nosler combined Technology Ballistic Silver tip
    85.0 Grains Reloader 25
    CCI 250 Magnum primer

    150 Grain Nosler Ballistic Tip
    82.0 Grains Reloader 25
    Federal 215 Magnum primer
    MV 3310FPS

    175Gr Sierra Game King
    79.0 grains Reloader 25
    Federal 215 Magnum Primer

    As mentioned by others, these loads have been worked up to and have shown no excessive pressure sign in my set up.

    I really like the performance and velocity that comes with Reloader 25, but it will take some time to get the barrel clean after running 10 or 15 down range.

    Last weekend I shot 34 rounds checking the accuracy of the Rapid retical set up on the new Zeiss scope, went back to shoot a 3/4" 100 yard group to finish.

    The reloader powder seems dirty, but does not seem to harm accuracy for longer shooting sessions.

    As far as performance on game, the 7STW does an exceptional job of sending 4 legged critters to meet there maker and really shines at 400+ yards.

    284nut, first of all, I like your screen name, as I am a 284 " Nut " myself. I noticed you are using the RL25' across the board as far as weights go. The RL 25 has really caught on with a few members on this forum, and everyones answer seems to be the same, ie, less pressure, more velocity, and low ES, SD. But I will second your opinion on the powder being dirty. It don't take long to foul the barrel. If you clean it at the range, it cleans up pretty decent, but if you wait til you get home, or the next day, well, have fun with that. I use Butches Bore Shine, and it does a pretty good job.
    I used to be a die hard RL22 man, with my STW's, but when the 25 showed up I tried it, and couldn't believe the difference. I finally switched all of them to it, and havent looked back. Nice load info, and welcome to the Brotherhood!
