Anyone have some favorite .257 Roberts handloads they'd like to share? I'm working up loads for my M70 for deer. I've had some experience with reloading this cartridge in my Browning BLR, but have never tried any other bullet weight besides 117grs. If you have a recommended preference of bullets for deer-size game in this caliber I'm all ears. Thanks

I reload the 25-06 but not the 257. I don't have any pet loads but can give you a few out of some different manuals if you want to try something new.


* make sure to verify any load you get from the internet with another source to make sure it is within safe operating pressures. I could make a typo that will split your barrel and blow the bolt back through your nose. :eek:

Yes, I'm going through my manuals now (Hornady & Speer) as well as those on-line from the different powder manufacturers. That's what I've been using. Not looking for shortcuts, but trial and error load development with reloads today seems so much more expensive than it was 30 years ago. Maybe that's what I'm really struggling with.

In the .25-06, while it runs at a higher velocity over the .257 Roberts, do you prefer the 100 gr., 115-117 gr. or 120 gr. bullets for deer?

I have the best groups with sierra 100gr boat tails using 38.2 grains of IMR 3031.My rifle has never been a tack driver . but with this load she holds around 1.5 inches

100gr with Barnes X Bullets and 117 or 120gr with conventional lead core bullets.

My 25-06 is a Remington 700BDL in a custom Fajen thumbhole stock. It can shoot 1/2 groups with a couple loads but all others I woudn't even take it hunting. Is your 257 consistent?

I've only tried one bullet weight so far in the M70: 117 JSP (round nose) and 117 SPBT. Seems to shoot consistently, but really haven't wrung it out enough. I will know later this week after some more range time. I've had good luck with IMR4350 so far, and the 117 gr. SPBT shoots very well in a BLR I have in the same caliber. I plan on trying some 4064 next (actually the only other powder I can find in my stockpile that seems to be acceptable per the manuals.

If I remember correctly, I use IMR4350 for most of my 25-06 loads. It's been a few years, though.

I only reload as needed now. Mostly in the Fall for our hunting rifles. Don't get to load or target shoot much these days.

Yes, I agree. I loaded and tested more in my youth than I do today. Other priorities I suppose. Now it seems I just dust off the dust and use what I've got laying around.

I started my rifle hunting career with the venerable .257 Roberts my Dad bought for me at age 12, I killed more bucks with that rifle than any other I've ever owned, I still bring it out on accasion today. After trying lots of them, the go to load for my Ruger M77 .257 Roberts is 47.5 grains of IMR 4350 topped with 100 grain Sierra Game King in BTSpitzer or 100 grain Nosler Partitions. The Sierras shoot a little better, the noslers held up a little better but never lost a deer with either. The gun performs well with 100's, in fact I dropped most the deer I shot with that load right in their tracks going for the high shoulder shot, and when I lunged em, they never went far either! I experimented with 117's & 120's but went back to the 100's as they simply performed the best, I found. Good luck, they are shooters, you can shoot...and that's the key right there!

Thanks for the info. I will try the 100 gr. bullets and see how they fare in the accuracy department. I am sure the 100 gr. .25 cal. bullet is more than enough for deer. I've used a 100 gr. bullet in the smaller 6MM Rem. for years.

Try 38 grains of WW 760 with the 100 grain bullet. Either Speer or Sierra. Shoot good in my 250-3000.

I have had good luck with the Sierra 90 grain BTHP in my 250-3000. I am shooting 36 grains of IMR 4895. If I were you, I would call either Sierra or Speer or both and ask them for their recommended loads. Both of them have techs ready to give you all the info you need. Good shooting.
