46-H4350-100 Hornady. Does the job near and far in my Ruger. 3050 fps and accurate, I've killed several whitetails with it and an antelope doe at 375 yards. Have yet to recover a bullet.

As of today 100 grain GS customs over 48 grains of Hybrid V100 ,RP brass and federal 210 primers. 1/2 inch groups at 100 yards and 1 inch at 200. Totally suprised as I just put my Rem 700 75th anniversary in a B&C stock and resighted it . 3200 fps.

100 grain TSX over 45.5 grains of Hunter. I'm not sure of the velocity, but it shoots 3/4" groups in my Hawkeye. It hasn't been put to the test on any critters yet, but I'm sure it'll do just fine.

I like 120gr bullets (Speer, Hornady, Sierra have all worked well) with stiff loads of 4831 (either H or IMR). Velocities are 2900+ and deer die just like they were hit with a 270, 280, 264, 308, 7-08, ad nauseam).

This past deer season, just to see what the hype was all about, I tried 80gr TTSX's with 4064. That combo works well, too.

Been shooting the Bob's since the 1960s and tried many loads over the years. The 115 grain Nosler Partition stands out in a combo of accuracy and bullet performance on Mule and Whitetail deer.

Loaded with 42-43 grains H4350 in two tang safety Ruger M77s 22" barrels I get 2820 - 2830 fps.

A Ruger 77 LT (long throat) shoots best with 45 grains H4350 at 2875 fps.

43grn RL19 117 Hornady interlock 2.788"oal, CCI 200's. Accurate and a fairly hard bullet that will hang together when you hit deer in a hard spot. I have taken deer out to 310yrds with zero issues.

43.5grn RL19 115 Nos. BT 2.88", CCI 200's. Even more accurate, but just by a hair, .6-.7 moa, consistantly over several months of shooting.

Just to back up what other people have posted, if a .257 won't shoot well with a 100-grain bullet and 46 grains of H4350, then there's something wrong with the rifle. I've loaded for about 12-15 .257's and the only one that wouldn't shoot with this load was a Ruger No. 1B with a very long and loose throat.

This is by no means a maximum load, usually getting 3000-3100 fps depending on barrel length, but with the right bullet will kill any whitetail or mule deer quite handily.

MD,
Just reread your signature line-
There's a lot of truth to it, especially in difficult times.

Have you found that you have to reduce that load with "+P" brass to get the same velocity/pressure?

If I understand correctly, the +P brass is thicker and has slightly less capacity.

My loads....

All +p win brass

100 gr. bullet speer, horn, sierra, nosler bt or pt.
Imr 4831 46 gr. CCI 200 and fed 210. Seat 2.800-2.85 o.a.l
chronos at 3050-3098 fps.
3/4 inch groops @ 100yds

117 gr Horn btsp
Imr7828 47.5 gr. fed 210 seat 2.900 o.a.l
chronos at 2950 fps
1/2 inch groups @ 100

Old school 117 Semi-spitz Noslers
Same as the above load
1/2 inch lower impact at 100 yds but shoots just as good
Have not chronoed these, probably won't.
Leaves exit holes in deer like the exit shown in the side of the elk earlier.

Loads have all dropped 'literally' deer and coyote. Other than the bear, who only made it 10 or so feet with the 117 btsp horn, no tracking has been needed.

I blame the easy shootability of the rifle allowing anyone to make very lethal and effective shots

Is there such a beast as a "wrong" 100 grain .257" bullet?

If a rifle looney is at a point in his/her life where all of the really important concerns of everyday life are well in-hand and/or well provided for, is it then OK of roll in the minutia?

With the 117grn Hornady I was hitting the lands at 2.92". I ended up at 2.788 becasue the Hornady Custom factory loads shot amazingly well at that length. I started hand loading specifically to duplicate that factory load. Since then I've tried a bunch of loads and components in the Roberts, but that 117 interlock is still a killer load.

Yeah, the 117 Hornady works really well.

Then again, just off the top of my head I can come up with at least a dozen different bullets from 100 to 120 grains that my wife and I have used on various deer-sized animals from several .257's, and they've all worked really well!

Looking for a good load for .257 using IMR 4064 and 100-120gr. bullets. Can anyone suggest a load that they've tried with this powder/bullet combination?

100 gr. TTSX
48 grns Hybrid 100V

COL: Forget, but just made it short enough to fit into the Remington Mountain Rifle box.

Accuracy was very good with 3 out of 5 in almost the same hole, the two out-lyers I put down to my shooting. Will test again in a little while with a chrono.
