Thread: 30 cal 165 Gameking SBT at 3100 fps

    30 cal 165 Gameking SBT at 3100 fps

    Does anyone use these bullets running them fast they work well at 2,650 fps in my 308 win, thinking about using them in a 308 norm mag for stalking but recall hearing the blow up on impact if run at 3,000 fps or above but can't remember where I hear/read it.

    Have used the 180gr Gameking in 300wm but my velocities are nowhere near book level
    180s should be 3000-3200 at book leevl

    can imagine pushing a lighter bullet even faster would be very messy

    game Kings are not the hardest construction so the concern would be massive bruising and potential blow up

    i use 185 grains at circa 3100
    but I used lapua mega before and corelokt now which seem to hold together better

    two shot yesterday with minimal fuss including one hind at about 35-40 yds!

    That's my concern they have worked very well at moderate speeds we know they go off like grenades when pushed to fast but how fast is to fast

    That is a bit toasty for a cup and core bullet I'd think.
    Perhaps the Mego, corelokt mentioned above or another bonded framed bullet?

    Like you say, they are great at modest velocities.

    The Barnes TTSX will do the job better than most at high velocity - They won't explode. they are designed not to break up, go straight through the beast & cut a clean blood channel through without bruising. The 180 grain bullet is 1.475" long, Needs a 1:11 or faster twist & has a BC of 0.484.
    What's not to like about them? Except price & avalability.

    They where my next choice but a 165grain I've used them abroad in the 308 to good effect yet are just hard to get than the ganekings.

    Simply Ammo sell 308 Barnes VorTX complete ammo with 165 grain TTSX for not much more than the cost of the projectiles. You could pull them & put them in your super whiz bang stick calibre. Then use the cases for conventional 308 loads.

    p.s. I've been thinking about doing the bullet swap thing to get 30-06 with the 165 grain Barnes option going, as that likes heavier bullets than the 308 ---- I realy like the 130 grain Barnes in the 308 & can buy those at Winkie's at Tain.

    I use these in my .300WSM, running them at 3050fps. They work just fine, they're very accurate plus they match the ballistics of my 168grTSX loads. At the end of the day, within reason it's shot placement that kills.

    Hi.
    These may be worth a try if you want to stick with a Sierra 165 Game King. Sorry it does not answer your original question but I thought it worth a mention. https://www.sierrabullets.com/store/...ia-165-gr-HPBT

    They were very accurate in my 30-06.

    Yorkie.
