Weatherby 257 magnum 80 grain Barnes TTSX for coues?

[dpr64]

Most likely will be using the weatherby .257 mag this year and the 100 grain Barnes TSX but the 80 grain Barnes TTSX really has me intrigued.... at 500 yards it is -17 only.. Would anyone provide any input on if the 80 grain is enough for our smallish coues bucks?

I shot a whitetail with my daughters .250 Savage last year with a 80 grain TTSX and it worked perfectly. The 250 is considerably slower than the Weatherby but I was really impressed, the shot was just over 100 yards. I have shot 4 whitetail with 100 grain TSX bullets from my 257 Weatherby with just perfect results. I love these two .25 calibers! So to answer your question a well placed 80 grain TTSX will put any deer down.

I have used the .257 100 TX and TTSX on mulies with spectacular results. My last big bodied muley was taken at 488 yds. with my .25-06 Ackley Improved pushing the 100gr. TTSX at about 3590fps. Bullet went in at front shoulder and out at left hip. Deer did not take a single step. I don't think you would need any more speed than that, and the extra weight of the 100 gr. helps retain more kinetic energy downrange, plus better ballistics at extended ranges. For a lighter chambering like the .250 Savage, I can see the added speed of the 80gr. as being beneficial, but not in a .257 Weatherby. I say stick with a 100gr. TTSX.

Do they make the 100 grain in a TTSX? I thought that was just a TSX?

Easily. Placing the shot is everything. Energy is a myth.

 

80 or 100 grain it matters not. Shoot the bullet that is the most accurate.

They make a100 ttsx it is extremely lethal, you won't be disappointed.

I sure wouldn't say "energy is a myth". But the 20gr. difference we are talking here is not nearly as drastic as it could be with the velocities we are talking.

 

I would not shoot a deer with a .223 Rem. and 70 gr. bullet at 800 yds. (only about 244+/- lb/ft left), but I would have no problem shooting the same deer with a .257 Weatherby and 100 grain bullet (about 926 lb/ft left) if I could place the shots where I wanted. The .257 80gr, TTSX at about 3600fps would only retain about 514 lb/ft. at 800 yds. That is just over half of the 100gr. at the same speed.

 

At 100 yds, just about anything will do the job.

 

.223 70 gr. @ 3000fps=1203 lb/ft

.257 80 gr. @ 3600fps=2030 lb/ft

.257 100 gr. @ 3600fps=2763 lb/ft

.257 115 gr. @ 3440fps=2827 lb/ft

.308 215 gr. @ 3100fps=4413 lb/ft

 

 

But I do agree wholeheartedly that placing the bullet where it needs to be is priority number 1. An 80 or a 100 gr. TTSX will do the job on a Coues ethically and cleanly out to most reasonable ranges.

[Big or Bust]

Speed kills and BC matters is what you are saying. I agree.

 

Placement comes first though.

Hmmm, seems that the 80 comes in ttsx and the 100 in tsx? What is the difference?

I'll say again....

 

The .257 ttsx comes in 100 grains as well.

I think that is for handloads only.... I don't see the 100 in TTSX in ready to go shelf ammo....?

I have taken several Coues from 200 all the way to 475 yards with my 257 WBY MAG using 115 gr. Nosler Ballistic tips. (look at my avatar picture)

[Hoss50]

I will be shooting the 115gr Ballistic Tips or 117gr Hornady BTSP. My rifle really seems to like the hornady but shoots the ballistic tips well too. I shoot 257 weatherby but they aren't maxed out. They are about half way between a 25-06 & 257 weatherby maxed out.

[firstcoueswas80]

Ya never specified factory loaded.

 

Try the 110 accubond load.

[dse]

Corbon loads the 100gr ttsx. But not very speedy, and really spendy.
