.260 Rem powders & 120/129 gr pills

[tabs4u]

I am trying to get the best accuracy and velocity reloading for the 120/129 grain bullets in me 21" Sako 75. I have H4350 but is anyone having better luck or experience with any other powders ?

4350 is usually as fast of burning of a powder that I will use with 120-129 gr bullets in the 260s I load for. I used to try Varget/RL15 with 120s (around 40 grs max IIRC - double check manuals) for 2800 f/s. Now I will use H4350 or RL19 with those bullets, gives me a better balance of speed and pressure with good accuracy. H4831sc is another I lean towards, last year I was loading 48.0 grs of it behind a 125 grain Nosler, for 2900 f/s in a 23" barrel. With 129 gr Hornady (either SST or Interlock SP) I shoot 43.0 or 43.5 for 2850 f/s

I had great results with H4350, I think it was 44.5 grs with a 125 gr partition. The load was excellent in two different 260's, just under 2900 fps, I got crazy pressure spikes and velocities with H4831 below max in the first gun I had so I never used it again.

I think you will have a hard time beating RL 19 in the 260 with those bullet weights for a combination of accuarcy and speed. I have had very good accuarcy with RL 15 and 120 grain bullets but have not pushed it for the highest velocity. For highest velocity you may want to try VV N-560, it may be the best for speed with the 125 grain partition, it is the fastest powder in my R 700 MNT rifle with the 140 grain partition and my best all around hunting load.

Thanks for the tips guys, I will try some RL19 if I can get it around here.
