Home Forums Hunting & Shooting Africa 257 Weatherby

Hmm. I have some 100gr A Frames somwhere. Might have to try them in my South Gate...

25 caliber Swift A-Frame bullets are an excellent hunting bullet and in a 257 Weatherby mag. this is a accurate ,fast killer and these bullets stay together very well too . good luck,Pete53

Jorge, load em up, they're little slap downers on white tail deer, also the most accurate bullet in my old FN.

Pete, were i you, i'd be over on the Hammer Bullets sight ordering the longest Hammer 25 cal bullet that would stabilize in that 7.5 twist barrel, talk about a Hammer! i saw that Davis guy shoot a Warthog at 417 yards with 338 Lapua Improved and 262gr Hammer bullet, vapor trail to, THEN through the Warthog, petals went through the pig too and landed 40-50 yards behind the pig at 10-1-and 3 o'clock, holy damn what a slap down!

Jerry shot was 250 yds took out both shoulders and found bullet just under off side hide

My brother had a 1961 German in 257 with the 24" barrel, He also bought 6 boxes of Weatherby 100 grain sciroccos and that rifle loved that ammo.

Mine was made in the mid 90s when WBY guaranteed 3 shot 1.5' groups. It pretty much does that but rarely better and sometimes worse.

After seeing deer shot stem to stern and what it will do to a big hog I would have no hesitation to use the 100 gr TTSX on an elk from my 257 Wby. That bullet is about perfect for that cartridge.

By god perfect Dan, good stuff buddy, this tells me my bullets loaded to 3450 will work perfect, your load impacting at 250 yards was most likely hitting at 3450 fps, tells me i can slam a Wildebeest at 25 yards and not worry about blowing the petals off before i can chainsaw the vitals, Thank You Sir!

The little 257 has just moved another notch up the ladder to take for plains game this fall.

Oldelkhunter, Thanks for that, i would have thought the 100gr Scirocco to be a bit too long.

JAH, yes, they're little burners that heat barrels fast, i've fired my old rifle two times, let cool a bit then fire number three, i havent threw up and fired at any game animal three times, so all good there.

GreggH, Thanks to you too, i need to revisit my 100gr TTSX load, will re-shoot with tip left in, has to make expansion a little slower, with tip removed a massive hollow point is visible.

We have never found for want with the tipped ones. Being that the tip is shoved into the HP it helps speed it up vs relying on tissue etc... I'd think.

Anyway some demand bigger expansion but we have never been left wanting on 100 TTSX

Yep, Thanks Rost, i went with the 100gr TTSX's with tips pulled because they're shorter than the 100gr TSX versions, hence my concern for rapid expansion, i think i'm barely scrimping by with a 1.050" bullet and 12 twist, as you well know a childs toy top begins to wobble as it slows it's rotation, my concern for the little 257 cal Barnes bullets to remain spun up tight enough to drill straight holes through larger African plains game, all i've ever hit with that rifle is smallish white tail deer.

myself i would use either Nosler Partition or a Swift A-Frame 25 caliber bullet they never fail , are very accurate in a fast cartridge with no pressure problems on warm days.

Pete, the 100gr A frame mics at an inch for me, it's the most accurate bullet in my 12 twist rifle, do you think it'd work on heavier plains game? especially that i run it at 3450 instead of trying for BTTW 3600 fps.

Trouble with me is if any other great example of a trophy animal appears i'll shoot it, a man simply cannot gear up, load up and go back to Africa for the cost of that trophy fee, even if he does, he may NEVER see that good of an animal again, that said, plains game animals from 30 pound Steinbok to 1800lb Eland, man that's a big stretch for my 257 WM and any 100gr bullet, i fear.

I would have thought so as well, he bought them for another Mark V he has but decided to try them in the old gun, nice cloverleaf groups.

^^^^^^^^^^Nice! Thanks OEH.

using 100 gr. Swift A-Frames in a 257 Weatherby mag. at speeds between 3600 - 3800 fps i see no problem on any plains game animal in Africa with this cartridge , but like i posted i have never been to Africa yet. good luck with your choice ,let me know how you do,Pete53

10-4 and Thanks, will do........................i'll have too, it'll be on video LOL!

Got the little FN out of the back safe yesterday morning, pulled it out of the stock and gave everything a good checking over then a cleaning and light oil wipe down, chrome bore cleaned right up with a couple soakings of Wipeout, S&K two piece bases and scope ring screws holding the old gloss 4-12x40 AO were all good and snug, forgot how trim and light this rifle was, went to the chronograph at first light this morning.

65gr Norma 204 pushed the 100gr TTSX with tip pulled to 3499 fps with COL of 3.235, COL of 3.170 went 3475 fps from the 25" barrel, dont know what either would correct to true muzzle velocity from 18 feet away, have three rounds loaded with each COL, will see which is most accurate when the winds settle and rains are gone, i've only shot a couple deer with the 100gr A Frames, [64gr N204, 3450 fps COL 3.200] they melt deer, i think this load will do a bangup job on plains game up to the size of Wildebeest, we shall see this fall.

You will rock anything you shoot with that load best of luck!!!!

my 4 - 257 Weatherby`s like these 2 powders best for speed and accuracy RL. 25 and RL.22 .
