257 roberts

[adigger]

I bought a pair of Remington 722 in 257 roberts and am looking for what best in deer loads I live in pa. I have imr 4831 and h 4350 powder to play with.

 

[ncageneral]

Either of those powders under a Speer 120 SPBT should work perfectly. If you can come across some H 100V it would also do well.

I got some 117 sst but have not got to play much yet . every use those ?

Disclaimer: These loads work in my rifle and anyone else should reduce by 10% and work up slowly.

My M77 with a 22" 1:9 Bartlein running 115gr Partitions over 48.5gr of RL23 and a 210M primer with an OAL of 3.025" is giving me 2962fps and 3/4" groups. High shoulder shot on a doe this fall broke both shoulders and exited. 20yards and down for good.

YMMV....

I have a bunch of those Speer 120gr BTSP that I was playing with using Norma MRP. I was getting sub MOA (0.70" 3 shot group) pushing them really hard....3042fps using 50.1gr. 50.6gr 3 shots were right at 1/2", but I had 0.001" head growth on all 3 of those.

My rifle really liked the Norma MRP for speed, but Norma powders have vanished, so I switched over to the RL23.

I did shoot a ladder using Hammer Hunter 103gr using RL16. My lowest fps was 2918 and the highest was 3168. I plotted all 18 shots I fired, with a 250fps velocity spread, in a 2.34" circle. The barrel was very new and my velocities kept climbing. The last 2 I fired were right at 3150fps and measured 0.18"

Hope some of this helps. Enjoy your Bob!

I have. Sierra 117 spitzer boat tail? I ran some through my 25- 284. They shoot good and they kill well.

 

[Drop Port]

100 NBT's were one of my favorites for culling deer

 

[std7mag]

Your 4831 with the 117gr SST should be a good combo.
As always, start low & work up.

I generally dislike plastic tipped bullets for deer. Bad experience with Nosler BT's so I use the Speer 120 SPTB's in the 257 Roberts and 25-06. The Roberts runs these at around 2925fps but it's a Bartlein barrel that's long throated especially for this bullet. The last time I took it to 300 yds it shot 4 into 3/4" and somehow, I managed to put one 2" away from the group. Still very good as far as I am concerned so I don't think you'd be giving up any accuracy because they were Speers. Hornady may very well do great in a 257 Roberts at slower speeds?

117 Sierras work fine on the Pa deer I have shot with thrm.

 

[Preacher]

Any bullet you use in a 257 Roberts.....will flat out kill a deer .....

Sorry to hear you had a bad experience with the Ballistic Tips.
In general, they are my go to deer bullet for any caliber/cartridge.
But i have learned not to hit the shoulders with one.
Ditto the Berger VLD-H.

For some reason it's reported that the 117gr SST doesn't perform as other SSTs do.
They don't expand as violently & hold together much better.
There is a good deal of talk about this from our southern cousins in Australia & New Zealand.

Use Accubonds!

 

[Orr89rocz]

117 hornady interlocks worked great for me. Dont use any of those powders but they should work. Have used reloder 19, 23, and H414.

my fav load now is 110 sierra gamechangers on rl23. Took a buck at 350 and seemed to perform adequately.

This is a Remington M722 Short Action, using loaded ammunition 2.775" COL. The .257 Roberts uses a 2.233" case in this Short Action giving you 0.505" of seating depth if you stick with the idea of not seating the bullet below the base of the shoulder.

 

[std7mag]

Use Accubonds!

If your rifle likes them, by all means yes!

For some reason it seems with the regular Accubond either your rifle really likes them, or it really does not.

Long ago I had 257's on a 722 and custom Ariska, plus a custom Mauser in 250-3000. all gave stellar performance with 100gr Partitions. I'm down to a 25-204 which will match velocities out of the old timers and the 100gr Partition is still working just fine.

 

[Kevin Taylor]

I have not reloaded in ages, but really liked 4831 and nosier partitions.

 

[AckleymanII]

117g Sierra and Hornady's are available, they are worth building a rifle around! Hornady is tougher than the Sierra, but I shot 10X more Sierra.

In most all the 25 caliber rifles, for deer, your powders are fine, and with a load worked up in your rifle, that is accurate, with a 100 grain Nosler partition bullet, you have a combo that will kill any deer, with proper placement of the bullet, any day of the season.

IMR-4350 and 100 gr Partition worked for 20+ years in our house. Two 700 Classics on long actions.
