I know there may be other and maybe better powders and bullets for the Roberts, but I am ONLY seeking success stories with these combos.
Let's hear yours.

I'm now loading Hogdon 100V, but thats not one of your choices, so I'll honor your request and not tell you about it

The only experience I had with BLC-2 was with my .350 Rem Mag. Either I had a bad batch or a standard primer just couldn't do the job (Speer manual suggested a normal primer).

In either case, pulled the trigger - there was an odd sounding pop-fizz and then nothing. Waited 45 seconds, pulled the bolt back and saw the wieredst thing...

The powder looked fuzed, like a cake of powder balls and the color had changed from a gray graphite color into a tan colored fuzed block.

I banged the bullet out, tried again. Did the same thing. And after one more banged out bullet...tried a third time. Sizzle and fizzle.

I swore off BLC-2 ever since then.

Now if you want to talk 4350's, I got lots of stuff to tell.

TC,

not in the Roberts, but I have used both powders in the 6.5 x 55 and the 6.5 x 57 with 100 grain bullets....

both shot very well in both cartridges...

however for the pair, in several rifles chambered in those cartridges, H 380 performed the best out of the two..with 100 grain bullets

BLC 2 performed just slightly better with 120s..

and that was using large rifle primers, not the magnum primers you see published to use with H 380 instead...

can't tell him about MRP either then can I ?

I would certainly entertain MRP for a completely different reason.

I just did not want ten other powders listed and no information to fulfill my request. I have other powders, but want to burn some H-380 and BLC-2 that I have

With 90 to 100gr. bullets and Wcc846( Surplus BLC-2 ) My cousin is consistantly better than MOA with his .257 Roberts. It does bark, however. roger

Several years ago, I tried BL-2 with a 100 grain Speer spitzer and the 100 grain Speer boat tail. My rifle ( Mexican Mauser, douglas barrel ) didn't like it a bit. The bt were very poor accuracy-wise. The spitzers were reasonably accurate but left me with very dirty cases. It seemed to me that the charge ( and I tried everything in the book ), didn't give enough pressure to seal the neck, so soot got leaked back. IMR-4350 or IMR-4831 were vastly better, accuracy-wise, with CCI primers and Winchester cases. My rifle has a long throat also.
I doubt that your rifle is much like mine, so the only way to see is to try. I'd try Speer, Hornady, and Sierra spitzers and start low and work up.
A small investment in other powders might just give you a lot better-shooting rifle.

I use H-380 in my 257 rob. Imp. with very good results. It may not be the fastest powder out for it, but it does produce very nice groups, and that is what I'm after.
