375 powder???
Where to start.....please help!

Which powder, H4350 or Reloader 15, would be likely to give the most accurate load for a 375 H&H with 260 grn Accubonds?

Thanks!

RL-15 for anything under 300gr (235-275).

H4350 for 300+

For the 260 grain Accubonds you could try H4350, H4895, Reloder 15, IMR4350, AA2700, AA4350 or Ramshot BIG GAME. I'm partial to H4350.

RL15 and 4064 have been the powders for the .375. H414 and 4350 for 300 grain bullets. I have a feeling Big Game will work really well as it has in my .338-06 and 9.3x62.

I'd recommend RL15, IMR4064 or Varget for your application. These all perform well in my 3/8" bore. IMR4350 was too slow for me, even with 300 gr bullets.

If you are talking .375 H&H:
IMR-4064 From 61.2 grains to 73.4 grains
Remington 9-1/2M Primer

Reloader 15 has been a very accurate powder in my .375HH with 270gr bullets. I would imagine about 74.0gr of RL-15 with a 260gr bullet would make a good load.

With the 260 grain Partitions my 375 H&H loves IMR4350
