257 Weatherby Bullet Options

Last year a young hunter in our group was using a .257 Weatherby. He was shooting Weatherby ammo with a 120gr Nosler Partition. His first deer at 120 yards completely obliterated the front of the deer. The deer was quartering towards him, his shot clipped the left front shoulder, high, then took out the right shoulder. From about halfway up the backbone forward it was just a mass of jelly. Two days later he shot another at over 450 yds. Less damage, but he didn't hit any bone this time. Obviously too much gun for the size of the animal and the shorter range.
 
Use the 100gr barnes exclusively and it has worked great. I see minimal difference in 110gr accubond and 10gr more isn't going to get me to use a more fragile bullet in a caliber that can have bullet blow up. The 257 is tailor made for mono bullets
 
I read somewhere, that the reason that hasnt happened is before the ole man passed he told his family to basically keep their **** hands off his partition. The quote was pretty close to that.
So seeing as its a family business I doubt itll happen that we get a modified partition.

Just putting the plastic tip on a partition would be a large bc increase. They have always shot great but man that low bc just kills it for me. Nosler could easily do the tip on them. I bet they could sell as many as they could pump out. ..

"Partition LR" just like they did with accubonds. Put on that tip and squeeze a little more bottail on the back and it would be awesome.

I get 3500+ FPS with 110 AB and R26. Right at 3400 FPS with 115 BT and R26. 10 twist so haven't tried anything longer.

Friends shooting 131 Blackjack in 25-06 AI but using 8 twist.

If you anticipate shots less than a couple hundred yards on game remember that velocity is tough on bullets.. choose accordingly.

Great cartridge!

Its results like this that made me shoot them in the head or neck.I want the meat...I'm not a Horn Hunter.
 
Got a 257 Bee coming today, love new rifles, never shot this caliber but have been reviewing a ton of loading data and the high velocities of this caliber. Most streamlined bullet appears to be the Berger 115 but I noticed a lot of gents have elected to drive the 100 grain Barnes TTSX to 3600 fps. Other bullets I have are the 110 grain Accubond and 110 grain Hornady Innerbond, real question, mono bullet at high speeds or lower speeds with cup and core? Any failures of the TTSX to penetrate and mushroom? Mostly big whitetails up in Alberta but could be the occasional elk or bear. Best direction to start loading in?
My primary hunting rifle is a Cooper Model 56 in .257WBY. I have used the 100gr Sierra Gameking on several Whitetails. It's very accurate out of my rifle using RL 25. Terminal performance has been good. This bullet in my experience dumps its energy in the animal, sometimes there is no or little in the way of an exit wound.

Been shooting the Barnes 100 grain TTSX & TSX for years! Haven't had a "failure" yet. Haven't lost a single animal. Basically one and done... bang 💥 DRT! Hogs, Antelope, South Texas Whitetail and predators... MK5 RC 1/2" or better with either Barnes mentioned about if I do my part...my favorite bee that I own..
