I have 3 .257 caliber rifles.
2 Standard Roberts and an AI. Love the rounds.
I have a great load for one of my Standards, using the 100 grain barnes triple shock over H-414.
It gives me 3100 plus And great groups , and this from a ruger RL with a 20 inch tube.
I would like to get the 110 Acubond to shoot 2900 and MOA , from one on my other rifles.
My other Roberts is a Beautifull Custom Springfield. 24 inch sporter weight Douglas barrel. My AI is a side safety FN with a 25 inch light sporter Douglas full length glass bedded in a nice chunk of walnut.
Does any body have any ideas that might help ?
So far i have tried IMR-4350 RL 19 and H-414 in both rifles. NO LUCK ! WHAT WORKS FOR YOU ?
Thanks guys ! ...tj3006

4064.

I've tried the 110 Accubond in a few rifles without much success. Hopefully your luck is better.

Years ago I had a .257 Roberts with a 23" barrel. My favorite load was a 117 grain Sierra at 2925 fps propelled by (original surplus) 4831.

That powder is long gone now, so I'd advise going with similar slow powders like H-4831, or maybe RL-22 or IMR 7828SSC might do it for you.

I used rl-17 in a lightweight 257 ai. It was not the fastest load, but it was the most accurate, by a long shot.

I went to Noslers pages and they really don't have many loads that run 2900fps. Might I ask why you need such speed from this particular bullet? My 257 Robts is on a Model 70 action and with 110gr AcuBonds it manages to produce 3/8" groups consistently however it is with considerably less velocity according to the book. I only load for accuracy though, not speed. I figure if it's anywhere near midrange it's good enough.

I run a 117 Sierra and max loads of IMR 4350 and get 2925 out of my 23 inch barreled ultra light rifle. Never tried an Accubond in the .257 and don't think I need to, accuracy is pin point and performance on game is fantastic.

I pretty much run 42.5 of H4350 in my Kimber for 110 Accubonds, 115 BTs and 120 Hornady Interlock HPs. I've clocked the BTs and Interlocks at 2750-2775 fps. I've had great accuracy with all 3 bullets (MOA or better).

I'm a simpleton, I use H4350 exclusively in my 257 Roberts and 6.5x55 with all bullet weights. It seems to work good enough and makes things easy.

Scott when I first started loading for my 30-06, I used 4064. For over 30 years I kept hearing 4350 was THE powder. I got some and 4064 works much better in my 30-06.

I too run a lot of H4350 in my Bob, 7x57 and now soon to add 6.5x55.

43.0 gr H4350 and a 117 SGK is my preferred load. I've also used 44.0 with the 110 AB - I did get 2900fps in a 20" Rem M7MS with accuracy hovering in the 1" category. For my rifle the SGK at 2850 simply gave me groups I just couldn't walk away from 1/2-3/4" groups with super consistency.

Regardless, I'm a huge h4350 fan.

I just checked my notes and 110 Accubond with 42.5 of H4350 was good for 2830 FPS from 22" barrel.

You might try either N-204 or RL19. I find the specific density of N204 (my stash of N204 is 20 years old so things might have changed) is very high so I can pack a heavier charge in a medium capacity case without taking up a lot of room. With the non-SC variety of 4350 powders, I often run out of case capacity too early.
I also have heard that RL17 also has a lot of mojo and works well in seemingly "miraculous" ways in many instances. I bought a pound but cold weather has cut short my range time so I can't say one way or the other how it works in the wonderful .257 Roberts.

My Roberts likes Varget. It does not,however, like Accubonds as well as it does Partitions.
GO Figure??

Varget , in the Roberts ?
Interesting !...tj3006

I have one old Rem 722 in .257 Rob. I shoot 120 NP's at Nosler's listed max load of IMR-4350. It is a consistent <1" load in that rifle. Don't know what it actually clocks.

No luck w/accubonds in my 6.5 X 06 so haven't tried it in my .257 AI. I have had best accuracy & velocities using 115 Partitions and Hornady 117's (any flavor) using R 19, R22 or H-4831.

I have shot accubonds in most of my rifles and they have aLL shot well. I shot them in a Savage 99EG 250-3000 and they shot wonderfully in that gun at about 2800 FPS. All EGs have a 1x10 twist btw..Its a long bullet and that can be problematic depending on twist..

I have two 250 Savages and one Ruger RL carbine and the best bullet I have shot are the Nosler partitions and and GS Customs..The WC&T bullets of yesterday shoot great in any .257 I have tried, but they are long gone other than I have about 200 of them left and probably that many loaded..Awesome bullet if you can find them..

For whitetail and Mule deer I have no complaints on the WW factory and Hornady 87 gr. reloads, up to a couple of hundred yards or so.

For my 250-3000s, 7x57 and 30-06's I have about settled on H414 as the best of the best. Its extremely accurate and highest velocity..

I shoot accubonds in my 25-284 rifle and accuracy wasnt so good. For hunting less than 200meters its fine but many other bullets accuracy was much more better. And i dindt even see so big difference beetween whit this accubond and other non bonded hunting bullets like B-tip how they work in game. So i didnt get any reason use those accubonds.

I use the 110 grain Accubonds in my .25 WSSM & they are devastating on feral hogs & South Texas whitetails. I know it is popular to poo poo on the WSMs & WSSMs, but I am sold.
I used to shoot .25-06s & they always shot best with .117 grain BTSP.

I use Varget with 117 grainers in my 250AI which has a case capacity approaching that of the Bob, with 117 BTSPs. Very accurate at 2950fps.

Might be worth a try in the Standard Bob?

My .257 AI does well with IMR4350.

Hodgdon's lists a load for 115 grain bullets in the "Bob" with Hybrid 100V at 3,049 FPS and at a reasonable 46,000 CUP

That's quite a load improvement.

My 25-06AI likes RL22 better than any other powder I tried.

my bob likes accubonds and h335

I don't know the speed but 45 grains of Reloader is giving me sub 1" groups with the 110 Accubond out of the Remington 700 Classic.

Since they shoot great in most 250-3000s at a bit under 2800 or there abouts and 2700 FPS in my Ruger RLs short tube, I suggest backing off that load and see what happens..

I've shot a couple of cow elk with the 250-3000 with that bullet at those lower velocities with excellent results. but neither were a 100 yards out. IMO about all 2900 FPS would do with that bullet is flatten the trajectory, by how much I don't know, but it would only be a little.

.

For me, 43-44 gr of h4350 and a 110 / 117 AB/SGK delivers 2850-2900.

I've found that H4350 is about as perfect as I've found for the x57 case based cartridges.

With 100gr bullets I've done well with IMR3031, 4064 but have not loaded the 110 AB yet. When loading 115's and 117's I've used a little slower powders and gotten satisfactory results in different flavors. I'd try RL19 or IMR4064 then gradually move to slower burn powders as well as maybe different primers. Sometimes a barrel just doesn't like a particular bullet.

Winchester Bob cases tend to hold more powder these days. I recommend trying H4350 instead of IMR. I only shoot the 115 partition, but it sure is accurate with H4350.

I use RETUMBO in my 25-06 and 110's. I get MOA accuracy out to 275 and then it open to 3 1/2 at 300 yards.

I seem to have mis- placed my .257 info, but remember with certainty both H 380 & H4831 shot well. That may not help because for my guns RL19 & 4350 both were some of my better loads.

Not trying to start a flame on accubonds but in three different calibers, had better luck with other bullets (.257 AI, 6.5 X 06 and .30-06).

For .257 AI, had best luck using H-4831, RL-19 and RL-22 but better accuracy using partitions. Also had great accuracy using 100 gr. Sierras and 117 gr. Hornady's in the .257 AI. http://porn.im.41812a00.410568...f83f79bc4ec4949a0851 grain

Newtire, I had the same problems with partitions in my 25-06's. Neither would keep them inside of 1.5" at 100 yards. The newer of the two likes the Accubonds with RL19 behind it - 53 grains seems to be the ticket for that one. The other one has more than 3500 rounds through the barrel and I'm guessing it's a bit more worn out than the other. Loads for it were best with H4831 but the speeds were down in 257 Bob range - 2850 or so.
Now that the 110 AB's have become one more Unicorn to try and find, I'm working on some loads with some Sierra 117 GK's to see if I can find something I can actually SHOOT more often!

Only on the internet do folks complain about 1.5 inches at 100 yards and 3 inch groups at 300 yards..Confuses me to no end and don't know how to reply to such..

Ray,

The reason for me to complain about 1.5" groups is simple; the rifle has consistently put 5 shots of 100 gr cnc bullets into .5" or better. After having to track down 2 different axis does and finding pieces of the cnc bullet, I decided to try something that would hold together a bit better. The AB was what I found.

Since it seems that Nosler has decided to stop producing 110 AB's, I'm starting the search over with the SGK's.
