Bricktop, you have likely done more testing with the 257 Bob than many on here, if given a choice of all the powders that work for it, which one would be your choice when using a 117 grain bullet? It would have to be that RL-19, without a doubt. It was the top powder I used with my No. 1 in .257 Roberts and it's provided the top velocities in this rifle, too. The 4350s would be a close second.
I have come here to chew bubblegum and kick ass. And I'm all out of bubblegum. I do tend to fit in well wherever I go in person. The campfire is the most outside exposure I get. No TV, no newspaper.

I have never tried Rel 19 in the Roberts, but IMR 4350 has given the best accuracy in my brother Model 70 with the Sierra 120 gr BTHP grouping right at 1/2 inch and my Sako 257 Rob Imp, IMR 4831 is the best powder i have used for this rifle.
