Thats all you need. I have used a .30/06 with 180gn Swift A-frames on those Wyoming Antelope but I was just a damn tourist hunter then. It still worked though, with a body depth holdover and a plop through the heart.
Used a heavier bullet because of the heavily promoted wind which was definitely there on range day, but not so much on the prairie while hunting.
When truth is ignored, it does not change an untruth from remaining a lie.
A mono would not be my first choice for antelope. The 125gr BTip has worked very well for me in a 30/06 on whitetails. Should be a good option for antelope, too!
Just about any bullet from the ‘06 would work well on pronghorn. If I were to pick a bullet, I expect the 165 grain boat tails would work very well (high bc plus reasonable velocity). Know the bullet trajectory.
If you want best results: Know the bullet trajectory, know the distance and if possible know wind velocity and direction. Down load an ap that all you need to input is bullet, velocity, wind velocity, elevation, height of scope over bore. The ap I have on my phone cost me something like $8. If you don’t have a suitable phone or ap, look up the trajectory and wind deflection on-line. Write the info down. Use a monocular or better yet binocular that gives you distance to the target. I was taught in the military how to judge distance. A range measuring binocular goes with me on every hunt any more. Way better than my ability via military training for me. I look at the ap on my phone before I get ready to shoot.
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally
Beings anything over a .223 with a 60 gr bullet is enough for a antelope, anything that shoots good and you are confident in, is good in your.30-06. If anything avoid faster expanding bullets because antelope are fairly tender and anything to explosive will destroy more than you want. I limit antelope hunting to a 243 because anything bigger does more damage than is optimal. A TTSX may just pass through with minimal damage and let the lope run a bit......
I am not a Barnes fan, but we have shot antelope with everything from a 22lr through a 375 H & H and 45-70. My last one was with a .25-06 and 100 gr. Sierra at 300 yards. The wind had not picked up yet so it was a reasonable shot. Wind can be a bitter enemy more so than distance. In an 06 I guess I would look at the 125=150 class of bullet in normal cup and core. Speed and accuracy are you friends. Good luck.
As a couple of people have noted, wind is often more of a problem than the simple trajectory. For that reason, a bullet with a high BC is preferred, since it will be less affected by wind. I'd be tempted to stick with a 165 grain bullet.
If you're upwind from them, you usually can't get within 700 yards of them. If you are downwind, it seems like you can almost walk up to them. At 700 yards, it's not a casual, easy shot, no matter what you load, so I wouldn't worry about that alternative.
Back when my only centerfire rifle was a .30-06, my deer and antelope load for it was with 150 gr Hornady SP bullets. They worked perfectly fine. Killed a few elk with them also...
I like the first bullet you mentioned the 130 ttsx but for 30-06 myself I would go with 150 ttsx. I load my 30-06 with 150 ttsx and H4350 at 3000fps. For the 130’s I’d probably go with varget.
The advantage of a TTSX or LRX for antelope is less meat destruction. Antelope are great eating but small, so lately I've tried to avoid bullets that might destroy a lot of meat if they hit, say, a shoulder. I don't take shoulder shots on antelope, but not all hunting shots are perfect, so a mono provides a little insurance.
My last antelope was taken with a 139 grain LRX out of a .280. Probably more power than necessary, but it worked great with very little lost meat.
A mono would not be my first choice for antelope. The 125gr BTip has worked very well for me in a 30/06 on whitetails. Should be a good option for antelope, too!
No experience with the 125SST.
That and the 125 NAB. At 3,100 fps, a real killer.
Now there may be better 400 yd. bullets, but for most shots, about perfect for that size game.
