257 Roberts Load ?

Bitman · December 27, 2009, 01:33 PM

Is anyone loading the 110 grain Nolser Accubond with H-4350 powder, in their 257 Roberts? If so, care to share your load data? Looking for something in the +P area. If not H-4350, any recommendations on loads for this bullet?
I also have Varget and H-4895 on hand. Thanks, Dave

There are only 4 SAAMI designations of +P and NO +P+ exist, and these are only for pistol.

Cartridge and Maximum Average Pressure (PSI)
9mm Luger 35,000
9mm Luger +P 38,500
38 Special 17,000
38 Special +P 18,500
38 Super Auto +P 36,500
45 Auto 21,000
45 Auto +P 23,000

At Nosler's web site, in the loading data they have loads listed, one is for Varget. All their accurate loads are listed below max charge weights.

If you are anything like I was as a starting reloader, I wanted the fastest load I could get. I soon learned they were not always accurate. I also found out that Joe Blows pet load was only specific to his weapon.

I do my workups with every powder/bullet combination I try. My goal is to get the most accurate load. If it also is the fastest, then thats a bonus.

Good Shooting!

Speer #12 has 257 Roberts +P.
Hornady sixth edition talks about it to.
From the standard 45,000 cup, to 50,000 cup of the +P.

Sorry, I cant help you.
I love my 257, but I only use it for varminting with 75gr's as its a heavy bull barrel and too heavy to pack around.
