7mm08 and 140 gr HPBT Gameking

  • Wondering if anybody has any proven results with the 7mm08 and the Sierra 140 grain HPBT Gamekings. I will be hunting Pa whitetails in the timber so shots will b fairly close. I do realize that it doesnt take much bullet to harvest a whitetail with correct shot placement. Just looking for some input on expansion, exit and weight retention.
    Thank You
    Ryan

  • Just been shooting a customers reworked 7mm08. Trued up model 7 Remington action, PT&G recoil lug,?Mullerworks #4 Sporter, 7mm, 1:8.77 ,5R, 20" McMillian BDL stock in Edge Technology. I would recommend 120 Barnes XXXMX, 140 Nosler Accubonds, 140 Barnes XXXMX, or 150 Swift Scirocco bullets.

    Shot loads from .3 to 1.5"

  • I am not a fan of the Sierra BT as a game bullet. The core and jacket tend to separate and penetration is poor. There are many better game bullets and
    the Nosler BT is one of them. I have had core separations as low as 25-2600 fps on quartering shots with small Whitetail.

  • I wondered about the S 140 Gamekings at higher velocities - was just dinking around with an assortment of 7mm bullets in a new 280 AI, trying to get a feel for what it likes. Chrono'd a H100V/140GK load at 3087fps, and thought to myself what a whopping mid-range load that'd be for big mulie bucks that'd be. Sounds like it might be a better bullet for whacking steel than for harvesting deer at that speed.

  • Hey 1Hole, I used to shoot a .270Win and for 1 year I shot the Sierra HPBT gameking. I hunt in Texas where "Hill Country" whitetails tend to be small, body-wise. I shot a very nice "Big-Bodied" deer>>about 170 pounds. The bullet killed the deer and put him down in his tracks! Sounds good! BUT the bullet never exited and I found pieces of it all over the heart / lung and off-side hide. It simply came apart. Believe it or not, one of the best "regular" bullets I found for "deer-sized" game is the "Hornady Interlock"... I have never had that bullet fail. One of the best examples of how that bullet performs was a deer I shot with my 7-08. It was at 216 "measured" yards and the deer was trotting away at a 1/8th angle to me. I put the crosshairs on the front of his chest and let'er rip. It hit a rib going in, tore up the inside like it was placed in a blender, exited out leaving a HUGE hole and hit the front leg almost blowing it off! The "Inter-lock" is really all you will need for deer sized game..

  • My gun loves the Nosler Partition bullets and it will b almost impossible to find a load that will beat group size. I shot a few deer with the partition and they performed very well. I have been looking for a different bullet to play with in the 7mm08.

  • my experience with the Sierra game king is supurbe killer, however i do not use the HP i use the SBT and they do not show seperation, i have used the 140Si SBT in 7-08, 7-08AI, 280Ai with excellent results. some have exited and some have not depending on the angle of the shot.

    The Nos BT also is great yet in my experience then never exit, just come apart in the animal, a number of WT and Mule to prove no exit

  • I use sierras 140g jsp and in my 7-08 Savage,  22" sporter they print at .630 to .820" at 100 yds and at 2793 fps.
    The nosler 120g hunting BT goes right at 3000 fps and prints an average of .700" @ 100yds and is a great bullet for antelope/deer as well. My COL is 2.780" on them.
    I aint fast.....but my aim is Deadly!!

  • 1Hole, Built a 7MM-08 in 1992 with a 24" tube and worked up a load with IMR 4064 and 140 Gr. Sierra Spbt Game Kings. Shot a very nice Eastern Montana Muley @ 450 yds and when I returned to Pa. I had the barrel shortened to 21" and I hunted about 4 more years taking white tails in each until my son confiscated it around 96. He has since killed 10+ white tails since all with one shot. I can highly recommend the Sierra GK's they flat work. If you want to try something different, try the 140 Berger Hunting VLD's and let me know how they work. The 130 are pure poison out of my 6.5X47 Lapua. Good Luck and have fun experimenting.

  • Like fishin-goat, I use the Nosler AccuBond in most all of my hunting rifles. I have not ever had one not pass through. The jacket is a bit thicker than the Nosler BT. The Partition is also an excellent bullet.

  • I built a Mauser 7X57 sporter on a VZ24 action a couple years ago.  I have worked up a bunch of loads and based on reading a lot of articles, the majority favor the 140 gn Barnes solid or the 162 gn A-MAX.  The A-MAX especially is supposed to be a real killer on medium animals like the coastal Black tail I hunt here in California.  Loaded to about 2700fps, they expend all their energy for a decisive kill.  And, at that velocity, the ballistics beat most faster, lighter bullets.  I use the Barnes 140 gn TTSX at 2800fps for pigs.  Most coastal deer are shot at 40-75 yd and pigs even shorter ranges.  So, 3000 fps is not required. In fact, the 162 gn A-MAX sighted at 200 yd will kill at 300yd easily with minimal drop, 40-250 within 4" and 300 only 10" drop.

  • I spoke with a Sierra "bulletsmith" whom I have gained much respect for over the years.  He told me I want the 150 grain spitzer boat tail from Sierra as an excellent deer bullet for up close or longer ranges.  Plan to shoot a moose with one this year.

  • Good posts above.  Used 140BTs, Sierra SBT, 130 SSP and SBT, 139 all on deer.  The Sierra, did well, frontal shot at 35 yds thru chest, destroyed innards, bullet found in gut pile.  Died w/in 30-50yds, from a M70 Fwt 22" about 2900mv.

    I really believe the Accubond is one of the best bullets in the 7/08 and if I run one again, it will be fed ABs FWIW.
