I am going to be loading some .257 Roberts ammo for an upcoming whitetail trip, I have on hand 100gr. Noslers, Partition, Accu-Bond and Ballistic Tip. Which would be be your choice, shots will be 100 yards or so.
Whichever is more accurate. (Bet the Accubond is 110gr)
Accubonds are the best of both worlds..
Accubonds are 110gr., accuracy by a slight edge is the Ballistic Tip. Any difference in performance on game?
I'll pick, the Partition if your shots are going to be close.
GW give the attached a look the NAB or NPT will be hard to beat. The NAB better at 257wby velocities.

Go with 110 Accubonds. I use them in 257 Wby and 25-06’s
What speed are you getting?
You can never go wrong with partitions
I use a lot of 100gr. NBT's with H4350 in my Ruger M77 MKII for deer and pigs with no complaints; several youngsters were introduced to big game hunting with this rifle and load.
I could use the 100gr. NPT and probably not detect any difference in performance on game.
Good luck this fall.

In general, a 100 grain bullet works best in 25 caliber rifles with 1 in 10" twist. My 95 year old shooting buddy loves 25 caliber rifles, and he says 100 grainers are the way to go. I can't argue with his 70 years of experience. In my old 25-06 the 100 grain Partitions shot bug holes at max charges. My current 25 caliber rifles with 10" twist are a 250 Savage and a 257 Roberts. 100 grainers shoot best of all game bullets in those, too.

I shot the 110gr AB's for a few seasons and was not that impressed with penetration. Switched to 100grE-Tips and they are mean indeed. Of your picks, the Partition is how I'd roll. They've always been great for me in 6mm/.25cal, soft enough in the front for good tissue damage, hard enough in the back to punch through.
I just ordered some 115 Ballistic tips. I’m gonna try them on pigs.
Isn't the 100 bt one of the heavy jacket versions? I wouldn't quibble about any of the three given decent accuracy. I'll probably switch to 100 ballistic tips when my 100 Hornady Interlocks run out. Only got 5 boxes left.
After over 40 years of shooting a 257 Roberts, I have to say most will shoot all the bullets you listed with acceptable accuracy. For me H4350 has been the powder of choice for 100 grain bullets on up.
I have shot deer with both the 100g BT and 100g Partition and bear with PT. Both out of a 250AI, so right around Roberts velocity. The BT is a well constructed little bullet. I haven't caught one in probably 8-10 whitetails I have shot with it. The partition I have used a little less just because my load with the BT shoots exceptionally well, but nary a complaint with its terminal performance.
The 100 gr Partition at about 2800 out of the Bob was my father's "big" gun for elk for well over a decade. He was a hunter, and an amazing field shot. He never had to shoot twice with the Bob and Partitions.
That said, I don't think they are a requirement for close-up deer, given the not-quite-magnum speeds produced by the 257. Shoot what you prefer. They are all good, and they will all work.

Unless he sized it too much I bet his brass lasted a good long time too. That's a mild load for a 257 Roberts.

He used the same box of 20 for his hunting. When he sold that gun and all accessories, I'd shot it more on a handful of deer than he had in 15 years of deer and elk hunting.
That was Nosler's accuracy load, btw, loaded with IMR4350. It certainly was mild.

Seems like he knew well what he was doing.
Maybe I'm an old stick in the mud, but over time I've come to believe most people are over gunned and under practiced.
For deer at "100 yards or so" I use the Hornady 117-grain RN. Very accurate and holes them like a German torpedo hit on the Lusitania.
He did. Sadly, I didn't get to hunt with him much. He knew how to get close, but he also knew how to shoot far, before the days of chronos, dial turrets, and range finders. His prize was a Salmon River mtn goat, taken in the late sixties.
I've used the 100gr Partition in the 250 Savage loaded to Nosler's manual max with very good accuracy and performance on deer. Shoule do the same in the Roberts. The only deer I've shot with my Roberts has been with Federal Premium 120 Partition. Also accurate and effective on deer.
I’ve had excellent luck from Ramshot Hunter & 100 gr NBTs which are nice & tough. I don’t think you can go wrong w/ any of those three, but can’t inagine spending premium dollars on deer bullets when NBTs kill stuff beautifully.
