42.0gr of 4350 works well for me Tried 4064 and didn't have much luck getting good accuracy

I prefer RL 19. Shoots 110 Accbonds extremely accuracte

There use to be a sticky that covered situations like this. Its gone now so I'll say it,You need to work up your own loads. If someone states a particular load you should always check your reloading manuals and see where it falls. If its anywhere near the Max you should start at your manuals beginning load and work up carefully.

A load that shows no signs of excessive pressure in one rifle may very well be dangerous in yours.

The very best and most accurate powder I have ever used in my
old Rem. 257 Roberts was IMR 4320...I can't remember what the
loads were now,but that stuff worked with every bullet I tried..
Killed a lot of deer with that old rifle..Reading you post brought
back memories..Wish I still had it.That was 30 years ago...
Good luck with your and be safe---Happy Holidays

I have used IMR 4350 and even RL 22 in the 7X57mm Mauser round with heavy bullets and gotten good results. There is no reason at all why IMR 4350 would not be even better in the .257 Roberts. After all, it is the same cartridge shooting a smaller diameter bullet through a smaller bore.

.257 Roberts in a BLR
42.5 gr IMR 4350
115 gr Bear Claw

Accurate & deadly
