257 Weatherby loading

I started my son with the 100 gr TSXs his first year and we got to see a few animals run a little ways. The two loads are interchangeable in my rifles so I let him use the ballistic tips. He stubbornly refuses to switch back, and it doesn't matter how persuasive I try to be. It's hard to tell a kid not to believe what he sees, and what he sees is deer folding. Over and over.
It probably wouldn't hurt to go up a weight, but its hard to argue with 11 straight 1 shot kills.Hes on a roll.
 
69gr rl22
100 gr Nosler
210 mag primer
3.25 oal

I run this same load with Nosler BT as well, same POI. I haven't shot an animal with them yet :)
 
At what distance are you guys useing the 100gr bullets .I was of the mind that the 115 to 120 gr bullet would perform better in the 25 cal.I am new to the 257 wby I do own a 270 win and use it with a 130gr BT.I find it to be flat shooting but after 2 trips to the range with the 257 I now have a new appication for flat shooting.
 
ive shot 3 head of game with the 115tsx and 2 with the ttsx.

mt. goat at 109yrds
moose at 250yrds
whitetail doe at 100yrds
all with the 115tsx

antelope was over 300yrds coulnd get a range
muledeer was 313yrds
with the ttsx this year

i would feel comfortable out to 500 with the wby for deer only if i have shot that far and had good data for drop and come up. i havent shot that far with my load this year so im going to keep it around 300yrds max.
 
Ha its not the 257 they hate .It that cramped up ride in to town in the back of the truck .:D

LMFAO!!!

I too am interested in the .257 WB. I'm looking for a 25 caliber that my gf can bench shoot, and maybe blast the odd deer with. Maybe I should start her off with a .243, but i'm really starting to take interest in Weatherby calibers.

How much deader do you want them? :p Actually, with some load combinations you don't give up all that much velocity and a 115ish Ballistictip or SST or similar can drop deer so fast that you won't even see them fall.


*off topic warning.
I've found that when people want to lecture on velocity not mattering, its best just ask to see their STW or .257 Weatherby or inquire as to what light bullets they're pumping out of their .300 Roy/Ultra these days.:rolleyes: 35-3600+ fps soft bullets hitting deer sized animals puts a jaw dropping end to the "speed kills" debate.
 
I killed over a dozen deer,a couple of pronghorns,an elk,and a mountain goat with my 257wby,all with 100gr bullets,either the 100gr Ballistic Tip,or the 100gr Partition.My rifle preferred H-1000 or anything else.
 
Yet another use for H1000. The more I use that stuff the more I like it, at least at longrange.

I had some good loads for the old H-1000,but when they made it into the Extreme powder,it seemed to change quite a bit.The new Extreme powder actually produced 120fps less than the old H-1000 did.I tried increasing the charge weight to match the velocity with the old powder,but no matter what I tried,I could not get accurate loads with the new H-1000 Extreme.About that time,I sold my 257WBY to a friend.
 
According to the book of Hornady Chapter 297 verse 4
117gr BTSP, H4831 thou shalt use no more than 61gr for a muzzle velocity of 3100fps and 54.7gr shalt thou use no less for a muzzle velocity of 2800fps.
There is no mention of H1000
This is the word of Hornady
Amen
 
reloader

had great luck with reloader 25 with both 117 sst and 115 barnes x with a fed 215 large mag primer seated as long as mag would allow 68.3 grns in the sst and 71grns in the barnes would start at 62 grns with both. went with the barnes due to poor expansion and bad meat dammage with the sst. both produced under .5 inch groups @ 100 yds.
 
My dies are Weatherby dies.not sure who actually made them.just full length resize the 7mm RM brass with 257 Wby die and your good to go.the neck will be a few thousands shorter but have been told its not a problem.all my brass is Wby 257 orginal ammo fired from the rifle.

Those loads are quite low compared to the ones in my manual, for 4831 i have a load listed for close to 3400 fps with a 120 gr spitzer, the min load i have listed is 3200 fps
 
7mm RM Brass

Thanks for the reply, I have only used 257 Wby brass myself. It seems if I was going to use 7mm RM brass, there would be no sense having the 257 Wby...

If you were to go and buy new 257 Wby brass you would soon see the value in resizing 7mm RM brass.:) 257 Wby brass is near $2.00 per piece. 7mm RM brass is about $0.65 cents a piece.
 
There's advantages either way. Necking down 7 Rem Mag brass is a whole lot cheaper.

Useing tougher Weatherby brass or the same thing with a Norma headstamp will let you load a little hotter before you start loseing cases to loose primer pockets. It doesn't matter much on a hunting rifle, but the Norma built stuff is more consistant.

I use Winchester 7mm brass in my boys .257, and Weatherby and Norma in my own. We both use the same load, 68 grains of IMR4831 with 100 grain Ballistic Tips and TSXs. Mine actually shoots a bit better with 1 grain more, but I like the idea of being able to use each other's ammo interchangeably if it were needed.
