.257 Weatherby vs. Whitetail Deer

Hey guys,

I've decided that for this year I'm gonna go ahead and get an Accumark in .257 Weatherby.

I've decided to go with a Zeiss Conquest 3-12x56 (30mm) scope.

I've been told that the 110gr. AccuBond is the way to go...is there not any heavier bullet weights a .25 cal., as far as Barnes or AccuBond goes???

I would really like to be shooting around 130-150gr. Barnes TSX...but I don't know if they make it in that size for a .25 cal.????????

Sounds crazy...but I just want something to have as much "pop" to it, when it impacts. I couldn't care any less about how fast it is.

Anybody got any suggestions, ideas, help, anything????

Re: .257 Weatherby vs. Whitetail Deer

Based on the projectile that you'd like to use, you may want to consider a 6.5mm or 7mm cartridge.

How about a nice 7WSM (or 7 Wby) with the 140 TSX? Plenty of "Pop" for most game at any reasonable range.

You could probably get a very heavy .257 bullet from a custom bullet manufacturer but then you would likely need a barrel with a faster twist then you would find in a factory Wby barrel.

Re: .257 Weatherby vs. Whitetail Deer

You have been looking at the .257 and the 30-378. Two ends of the spectrum. I think varmint hunter is correct. Go with something in between. You like the Weatherby, so get a .270 Weatherby or a 7mm Weatherby, or a 300 Weatherby. Worry about the extreme ends of the spectrum after you have your go to hunting rifle.

jmho, Steve

Hey Steve,

Good to see you chime in.

Yeah, I guess yall are right...However I did a home-made ballistics comparrison chart using ALL 4 calibers, with their bullet weights & types, that I am interested in...

Here are the results:

1.) .257 Wby. / 110gr. AccuBond - M.V.: 3,460 / M.E.: 2,950

2.) 7mm Rem. Mag. / 160gr. Barnes Triple-Shock X - M.V.: 2,940 / M.E.: 3,071

3.) 7mmSTW / 160gr. AccuBond - M.V.: 3,100 / M.E.: 3,414

4.) .30-378 Wby. / 180gr. Barnes Triple-Shock X - M.V.: 3,360 / M.E.: 4,513


These are the results I found.

If you look closely...the .257 Wby is NOT that much faster, nor is it that far behind on its energy, than the 7mm Rem. Mag.

I used to shoot a 7mm Rem Mag. for a LONG time...it's still one of my all-time favorite calibers!

So, why not get better ballistics, with virtually the same energy?

I was just saying that I AM getting a .257 Wby. Accumark for Whitties this year...however, I was asking is it possible for anyone to put a larger grain bullet in there...somewhere around 140gr.???

Don't you think that would be a deer killing machine!!!???

A .257 Wby. firing a 140gr. Barnes TSX!!!

Re: .257 Weatherby vs. Whitetail Deer

Slayer, +1 on what the other two said. I have been telling you that the .257 is the cat's meow. You just dont want to listen. Factory loads stop with 120 grain bullets in 257 Wby. You can get heavier, I've shot 125's and 130's but they get harder and harder to stabilize in a factory barrel. The 125's work well, but finding them is tough, need a custom bullet maker and then reload them. Seems to me that the deer season will be over before you can make up your mind. Get the 257 and dont look back or second guess yourself. The 257 will dispatch whitetails faster than you can ever imagine. The others cant do it any better!!

Re: .257 Weatherby vs. Whitetail Deer

You would have to re-barrel specifically for that bullet in order to get it to stabilize. The calibers built on the 6.5mm bullet will give you that long skinny bullet w/ high sectional density.

Steve

PS

I think you should get one of each. It is too hard to decide, and it would be much more fun. At least 7 new rifles, one for each day of the week.

Hey Jim,

Good to see you in here, too!

Oh trust me...I'm getting an Accumark .257 Wby. That's final!!!

I was basically throwing out that ballistics info. for comparison purposes only.

I am planning on using the factory Weatherby loads with the 110gr. AccuBonds.........for now.

I don't reload...however, I wish I did...but I just haven't prioritized my money properly enough to purchase a reloading setup.

However, I think I might treat myself to one this year for Christmas!!! Hahaha!!!

Then I can start experimenting with my 7mmSTW!!!

That's gonna be fun!!!


I was just saying that don't you think for 0-300 yard shots that a .257 Wby. with a 140gr. Barnes TSX would be one BADD mama-jama!!!!


Hey Jim & Steve...@ what distances do the heavier grain bullets get "flimsy" traveling through a factory barrel?
