Powder for 257 Weatherby

[Gpkhill2]

Ok Guys, Thanks in advance. What's everyone's thoughts on powder for a factory Weatherby Vanguard in 257 Weatherby with 110 gr Accubonds. I have RL 23, RL26, H1000 and IMR4530

 

[Jud96]

RL26 and H1000 would be the two I would test and pursue

Just bought a 257 Bee as well, and agree with above, most gents have great results with 26 and 1000.

Best accuracy we've seen is with H1000. Going to experiment with RL-26 when weather cools off to conserve the H1000.

The 257 Bee is not picky about loads. Any slow burning powder matched to the bullet weight will invariably give good groups and speed. I use what I can get hold of easily and that is 7828SSC. Meters well, top velocities with the heavier bullets I like and 1/2 MOA loads with 5 different bullet makes/weights. Most are so easy to load for they will shoot Weatherby Select factory ammo, at 40 bucks a box, into well less than a half inch for 3 shots. If it wasn't for wanting a different bullet than the 100 grain Hornady Interlock for Elk or Moose (it is a great bullet on Deer and Antelope but a little fragile up close for the heavier game), I would probably just use the factory ammo.

Thank You to everyone. I have 6 or 7 pounds of 26 and 3 or 4 pounds of H1000. But my 7 Rem with heavy bullets like 26 also. So i may start with the H1000.

I would also try 100 grain bullets,Barnes ttsx etc mine shoots very small groups when I do my part!!

Imr 7977 did great with mine with both 100 hr and 115-120gr bullets. Great accuracy, sub moa with all bullets i tried and velocity both 3550 w/ 100, 3300 w/ 115-120 in a 24". Plus temp stability with decopper added. Its always available here as well.

My 257 WBY loves Rl22 and the 100 gr. Barnes TTSX.

 

[orifdoc]

Mine likes H-1000 and 100gr TTSX. I tried RL22, but wasn't quite as good.

H1000...or Retumbo if your barrel is over 28" long.
