What you are talking about here is the "lazzeroni philosophy". some believe in it, some don't.
You ought to get on his website for further study

I used the 100gr TSX in a 257 wby loaded to 3500 on Exotics. Killed very well. But the 115 Partition did great at 3200 also. I used a then wildcat 6.5/284 (24") with the 125 Pt and 120 NBT right at 3200 ( I used Winchester brass) and they were both "outstanding" on antelope, flat shooting, just a joy to use. I also load the 120X in a 7mm Rem Mag to 3500, and it was a Lazer! The 240wby/90X @3500 was also a dream to use. I have some 120 TTSX (made for the Blackout) I'm going to try out in my 300WM, along with the 130 TTSX. Any coyote to mule deer would be in trouble, ha. I admit I like more weight on elk size critters, but for everything else, a light bullet in a Magnum case (that doesn't come apart at close range of course) is a Gee Wiz killer! Caveat...I don't shoot at unwounded Game beyond 375 or so. Up to that, even that WY Wind had little effect on my loads, and that's saying something! ha Good luck to you Pard.

Before Lazzeoni it was the Roy Weatherby philosophy.

Works like magic!!!

in my 257 Weatherby mags. we have used for last 15 - 20 years 100 gr, Nosler partitions & 100 gr. Swift A-Frames at around 3800 fps both have killed bigger bucks fast in Northern Minnesota and out west in Northern Montana . last fall 2020 in Minnesota i used 115 gr. Berger bullets at 3400 -3500 fps with Reloader 25 accuracy was excellent and i killed 2 larger whitetail bucks in Minnesota 1 buck dressed 175 lbs. jump up fell down dead other buck that dressed 205 lbs. went about 40 yards and fell over dead. yes speed does seem to make a difference for my son and myself . i just ordered a Brux barrel with 7 1/2 twist to chamber another 257 Weatherby mag. with a 28 inch barrel contour #4 to be installed on a Weatherby mark 5 action. i wanna shoot the 128 gr. Hammer bullets,131 gr, Black Jacks and the new Berger 135 gr bullets with this rifle out west for deer and elk.

Another one. Not a max load BTW 5 shots

The only projectile I've used on game from my 257Wby is the 100gn TSX @ 3650fps. I've taken a black bear, pronghorn, cow elk, and a bunch of deer. I had one Mule Deer buck go <50yds over a fold and into a draw but I really didn't' have to track him. Once I got to the point where I could see down the draw he was laying right there just barely out of sight from where I "lost" the visual on him. Everything else has died within sight where I could walk right to them.

Over the last 50 years or so I haver owned and played with several rifles that shot at 3400 up to about 3600 FPS and so far my overview on super speed bullets' for killing game has not left me very impressed considering what I had to spend on powder and bore life from my 7Mags, 7MM STW and 30/378 Weatherby mag.

As of this writing I have NO big game rifles and loads that shoot faster then 3000 and most go about 2250 to 2700. My only "fast gun" is one of my 270s which shoots 130s best, so I have a load that gives me 3175 FPS from that gun, but even my 300 mag is set up with 200 and 220 grain bullets to I don't get even 3000 from it, but it doesn't matter. Kills are VERY good with it and I get no erratic results like I did with the super speed bullets I tried before.
Overall I have had better results with them then I got with the super-speed guns.

Shoot solid expanding bullet in the super fast guns for best results, but even then you can get some wild internal trajectories from impacts much over 3000FPS, which are very possible if you have 3500 to 3650 at the muzzle. I bit more weight and a bit less speed seems to work better for me.

I really like soft lead at low velocity. Pigs don’t even squeal.

It means with the high speed of 3700fps you are going to get away from exit holes. As long as you put the bullet in the vitals. boom flop.
Unless you use a quality constructed bullet, you won't need an exit..

I always wanted to try the 22-250 (1/14) with Barnes 45 grain bullets around 4K. Alas I probably never will.

130 Accubond at 3300 FPS out of my 264 WM has been one shot lightening bolt for many deer and antelope. Retumbo powder.

ditto for the 125 partition . Same cartridge and MV.

The Berger 140 video hunting at 3200 works well. If you're going for speed I'd try the 100 grain partition.

been wanting to try some 120 bt's runnin' bout 3,400fps outta a 7 rem mag.

I’m currently trying to work a load for my fathers 257 Weatherby. I’m partial to Nosler bullets, and was thinking to go with the 120 Partition. Can any of you 257 guys offer any recommendations?

RL25 and 120 Partition. The other is RL33. I know the 25 load is in a Nosler manual and runs around 3250’ish and is dime sized accurate in a couple different 257’s.

Just my 2 cent's worth from years of experience. I have found over the years matching the bullet performance envelope to the velocity is more important than just about any other factor. I've used Partitions for a very long time, but found in high velocity situations they tend to come apart even more violently than when pushed within their design envelope. If you shoot a deer, elk, or other at 100 yards with a partition moving along at warp speed, don't be surprised to see massive damage inside, on the far side, and have lots of metal fragments and bone fragments in your game meat.... in those cases I use bonded bullets like the excellent Nosler Accubonds, or Barnes TTSX or similar...

As for reloading, I use H4831 for most of my overbore cartridges and it seems to do very well in most cases. The 257 W is teetering on going with RL26 or a similar powder , which is a bit slower burning than H4831 and is reputed to be very stable ....

Yep, that

The 257 Wby gets a 100 gr TTSX here. It is a bolt of lightning on deer and hogs. Have been thinking lately of the Nosler BT of the same weight just for research sake.
