Just ran the ballistics on the bullet I'm hoping to use for the upcoming antelope hunt

Barnes 130 TTSX
300 Wby Mag
3650 FPS

sighted in at 300 yards it is

2.2 @ 100 - 3377
2.9 @ 200 - 3120
0.0 @ 300 - 2878
-7.1 @ 400 - 2648
-19.21 @ 500 - 2431


NOT that I would ever shoot that far....but extending the numbers out, my acceptable fps/ft-lbs to reliably expand a bullet and have sufficient energy (going by the general deer sized of 1000 ft-lbs and 2000fps for reliable expansion) is a hair over 700 yards!! Drop is 62 inches lol, but surprisingly there is only 37" at 600. . And its still only taking .775 seconds TOF lol.

Now I also ran the 165 NBT, just for kicks, it rises higher, and drops faster, and loses velocity nearly the same according to this chart.

Just thought I'd share some fun numbers I just read

    It appears that if you get a good hit, you can kill a goat in Alec's back yard from here.

    I hunted antelope years ago with my 300 wby mag with nosler 125 gr ballistic tips, and know it was over 3500 fps. I don't have the chart, and they shot good. Those 125 grain ballistic tips did a good job on the antelope though. Good luck.

    In defense of MHS, I recall an article by none other than Craig Boddington stating that he preferred the 'fast 30s' on pronghorns. I personally prefer something a bit lighter, but it's kind of hard to argue with the man's experience and success.

    I also have had the pleasure of hunting antelope with Dan (MHS) twice, and have no doubt that he knows what he's doing. If he's comfortable using a 300 Weatherby, I'm sure as heck not going to tell him to use something else. Give the man credit for knowing what works for him.

    Gun control laws make about as much sense as taking ex-lax to cure a cough.

    I know he is getting these numbers with the 130gr TTSX in his 300Wby - because in my 300 win mag with that same bullet I am getting across the chrony on the average the following.

    Bullet
    130gr TTSX

    Powder
    Norma MRP

    Brass
    Winchester

    Primer
    CCI250

    Velocity fps
    3512 fps

    COAL
    3.319"

    Group
    0.725" (3 shot)


    100 +2.3
    200 +2.8
    300 -0.8
    400 -9.3

    BT,

    Mind running those numbers again for me? The actual rifle weight is 9.5 fully loaded/scoped/slinged. Curious, but 30ft-lbs sounds about right.

    Thanks Jerry!

    Seriously, I WAS going to use my 308, but the game changed when I got a not always easy to draw tag on a prime ranch. That stretched string flat trajectory takes a LOT of the guess work out, because those who have hunted goats can all confirm....those range finders don't ALWAYS work on em. Small critters, the light fur and light color can make a solid range a bit more difficult.

    Yes, the bullet is much stronger then needed, but I'm looking at that arch....that is basically a hold-on-fur set up to probably 450 yards.

    I'm likely going with a 257 Wby as a more sensible choice for future goat hunting, but that ain't built yet. The 300 is ready to go, as is the 308, and thats going as well, on back up duty. Also have toyed for a few years with the thought of a 240 Wby as well.....
