I drew an antelope tag this year and am considering my options as to which rifle to take.
Right now I'm debating between my 257 Roberts and my 6.5 x 55. Both rifles are Remington Classics.
My last buck was taken with a 100 grain ballistic tip out of the Roberts. I've got a load with 100 grain Sierra's that are shooting well out of this rifle also.

The 6.5x55 will handle the ballistic tips well and currently I have a load with 125 grain partitions that show promise out of this rifle. I'm leaning toward this one as I've taken antelope with the 257 before and would like to try something new. For an antelope I'm thinking I'd prefer the ballistic tip as at the Swede's speed the partition may punch right through.

I'll probably take one of these rifles along and also my 264 Mag. The 120 grain Sierra bullet groups best out of this one, but 125 I've also used 125 grain partitions with some success.

Then there's the 25-06, 7x57, 30-06 and a couple of 30 caliber mags I haven't really considered.

Looking for some help from you antelope hunters out there.

I took a blacktail a couple of years ago with a Ruger 6.5 x 55 with a 100 grain Hornady SP, with an MV of 3350 fps...

I have also taken a few with a 260 shooting a 100 grain Ballistic tip, with an MV of 3350 fps.. yet recoil was low enough, I never lost sight picture with the scope on 4 power, and the deer was at 300 yds... ( although I was cheating as I had a rest off the hood of a Ford F 250 at the time...)

The Swede will take the 100 grain BT or Hornady SP and shoot them very accurately....with velocity in the 25/06's MV....3350 fps...

zero it at 3.5 inches high at 100 yds, and check out the ballistic charts to see how flat shooting it is out to 400 yds!!

You've certainly not listed a caliber that isn't capable of getting the job done. Which do you feel comfortable shooting? What rifles do you have in each caliber?

If it were me I would try the 6.5x55 with 120 grain Ballistic tips or 100 grain Partitions. Antelope don't need much of a bullet to stop them but if you make a bad shot on them they can go for miles.
I am in the same boat, I have a 6.5 that I am working on loads with the above bullets but I also have a .257 Roberts that will be together and shooting in a month or so.......................
Decisions decisions.

snellstrom. You are gonna love the Roberts.
Get your self someH-414 and and some IMR-4350.
As for your lope hunt, if the teritory is real flat and there is nothing to hide behind,I,d use the .25,06. but if you can snek up a -bit Pick , witchever load and rifle is the most accurate...tj3006

TJ I am already a huge fan of the Roberts and have been since I was just a boy. I've wanted one my whole life and this is "my" first one. My gal has one in a Ruger Ultra Light that is scary accurate with 100 grain Sierra's and IMR-4064 but it is "her" rifle this Roberts on the workbench is all mine. I'll give the H-414 a try and I always try IMR-4350 in about everything as it is a favorite performer for me.

Good luck on you endeavor Reloader2 and sorry for the minor hijacking infraction.

Congratulations on the tag by the way. I happen to have drawn one myself this year, only this year it is for archery.
Either of those would be fine, Antelope aren't all that tough an animal. I think I'm with you on the bullet choice too for them in the Balistic tip, and would save the Partitions for something tougher if between the two choices.
I say go with the caliber you haven't used before on your choice of weapons just for the heck of it, and don't look back. Good luck.
PS- if you have never tried a decoy before on Antelope, you may find it exciting and fun if you have somebody to "work it" for you; even if alone probably too. During the rut anyway, they really take notice and will come to it...sometimes too fast for ya'; 'yikes'...ha ha.

My last trip to Wyoming for antelope (05)I used my Sako in 6.5x55 to take two nice does. I used 120 grain NBTs at 3000 fps, which performed as expected - they hit like the hammer of Thor, even though the bullet and jacket completely separated.

My 6.5x55 went with me to Wyoming last year. 120 grain Balistic tips running right at 3,000fps put them down as well as anything I have used before (.25-06, .30-06, .308, and others). If I get drawn this year, it will be my gun again.

My wife and I use 100 grain TSXs in our .257s with great success on antelope. I used 129 grain Hornady SSTs in my 6.5X55 last year on two antelope does and a nice muley buck. The worked real well. At the modest velocities of the Swede the opened up very nicely and created great wound channels. I assume this though, because all three exited.

Either the Roberts or the 6.5 X 55 are excellent for speed goats.....as previously posted...H-414 is the powder and almost any 100 grain hunting bullet will do fine.

Again, either would work well. I'm a 6.5 fan so my choice obviously would be the Swede. I however don't like plastic tipped bullets (other than varmint bullets)and I like to load a bit heavy for caliber. If your rifle will shoot 129gr Hornady SP Interlocks well (I know, it's retro as hell) I suggest them. I shot 2 deer last year with a .260 Rem loaded with that bullet to 2800 fps give or take and I'm quite impressed with their terminal balistics.

For long range prong horn hunting the old 264 Winchester is tops.

Most anything bigger than a 22'll kill an antelope. If you drew your tag in Wyoming, make sure the diameter of your bullet is at least .23
