Hello,

Looking for anyone who has some experience with 100 grain slugs in .257? Primarily for the .257 Roberts. I have been using 117 or 120 grain slugs for my big game hunting with the Roberts, but have seen several articles lately touting the 100 grain slugs. Any experiences appreciated.

I have never owned a .257 Roberts, but my 25-06 is on it second barrel.

I like to experiment and have shot a fair amount of game with 115, 117, and 120 grain bullets in .257 caliber.

However, my dad talked me into trying the 100 grain Nosler Partition and I am quite pleased with the performance.

Between us we have shot a pretty good representation of coyotes, antelope, deer, and wild hogs with this bullet and have been very impressed. It just seems to kill better than the paper ballistics would suggest it will.

Just yesterday my dad killed a heck of a nice wild boar with a great 275 yard shot with his new .257 Weatherby. That hog was leaving the country but a well placed 100 grain Nosler Partition put him on the ground right now!

My dad and I have killed more wild hogs than most people would believe with 25-06 rifles loaded with the 100 grain Nosler, it just plain works.

I would think that in a .257 Roberts the 100 grain Partition would be a great choice.

duckster,
I have been using 100gr. Sierra spitzers for a lot of years and a lot of deer as well as one Bull Elk and have been extremely pleased with their performance. I've never had a Deer(or the Elk) take a step, I hit a running deer in the guts a couple years ago, same result. Another bullet that works very well on Deer is Sierra's 90gr. HPBT. They don't pass through the animal but that never mattered to me as long as they drop where they are standing. The above bullets turn the lungs from solid to liquid form. Another plus is flatter trajectory, I never thought that 15-20grs. of bullet weight was worth a loss of 300+ fps.

As long as the deer you're talking about are whitetails at 150-ish pounds and less, then 100 grain bullets are plenty in the Roberts. It's no problem to juice 117's up to better than 2900 fps, which would likely be a slightly advantageous load for a 200+ pound muley. But I certainly wouldn't turn down a shot at a 300 pound, 30 inch mule deer if all I had was a 100 grain Partition!

What it really boils down to is, which shoots best in your gun?

I have been using the 100 grain Hornady Spirepoint for 2 years now, in both 257 Roberts and 25-06. Real pleased with both on whitetails. Seems to kill just like a 270 and 30-06, which I also use.

The 100 grainers are more accurate in my Ruger 77 Lt.wt. than the 117's. My gun doesn't like max loads and I get decent velocity with the 100's loaded with 39 gr. of RL-15. Because of the accuracy I am confident shooting whitetails in the neck or spine and don't have to track.

One day my buddy and I were working up a load with RL-19 (that works fine too, just more powder) and this ol' chicken flies up on his grader blade and he says "Shoot that chicken"! And I said what if I hit the blade. He said you ain' gonna hit it; shoot that chicken! So I shot the chicken. Feathers went everywhere and he was laughing his ass off. Later on I found out his wife was a bit unhappy about the death of the chicken as they had a previous discussion about its worth around the place. But the 100's perform well on chickens too!

I am wanting to try the new Accubonds in 110 gr. and have posted request for info or opinions and received no replies so I guess no one has tried them yet. Ought to be great on deer (and chickens!). Merg

Using my .257 Roberts I have put a very nice whitetail and a excellent Muley on the wall using the Winchester 100 grain silvertip.
I used that same gun to drop a doe this last fall in it's tracks and have never had to shoot any deer twice with it.
As far as I'm concerned.....100 grains of properly placed .257 Roberts is a good way to put venison in the freezer and put a trophy on the wall.

I have hunted for years with the 100 grain Sierra in my 25-06......down right accurate and drop'em dead in their tracks lethal.

I've used that bullet for everything from rabbits (head shots) to Elk with total confidence.

IMR 4350 was the best powder I found.

Some will say that the 100 grain it too light for big game....they are wrong. By the same token, you have to take a lung shot...it litterly turns the lungs to jelly and drops them in their tracks.

My Roberts is a Mexican Mauser with a 24" Douglas barrel. I drew for a late hunt in the fall of 2003 and shot the biggest buck of my life. It was a 4-pointer, but had a big body. He was broadside to me and all his senses were riveted on the doe that was between he and I. Since the other does were starting to leave, I took the shot over the doe and spine-shot him at about 75 yards. The Speer 100-grain spitzer bullet went through his spine just forward of the diaphram and exited, having penetrated about 11" of deer. He went down but he got about 25 yards downhill while I watched. I got 192 pounds of meat back from the butcher. I highly reccommend the Speer 100-grain bullet for deer. If you want a pic, I'll be glad to reply to a pm.
Earlier that day, I hit a coyote at a bit over 400 yards with the same load. The load that I use is 45 grains of IMR 4350 in a Winchester case with CCI primers.

Thanks for the experiences, looks like I might have to give the 100 grainer a try.
