I am reloading cartridges for my .375 H&H Magnum BRNO ZKK 602 and I'm planning to use 300gr. Nosler partition and IMR 4350 powder. I'm looking for a velocity of approx 2450 fps.

Wondering what other forum members have experienced with this combination.

Thanks

A google search of hodgdon or imr powders will provide info on all their powders. I looked and you can check me, but they show only a MAX load, so back off 10% (which should be close to what you are seeking):

300gr 78grains IMR 4350 (compressed) 2620fps

They do not show bullet make or primer make or type, but I'd use a standard rifle primer. The COL as 3.60".

Hope this helps. Kudude

I'd look here:

Nosler shows lower loads and velocity with IMR 4350 than I expected. I would use their data as a baseline and work out loads for your gun that shoot best, then chrono to find out where you really are.

Also, watch working up in the cold and then taking them hunting someplace hot.....

I've had good luck with both IMR and H 4350.

Cheers,

Dan

I worked up some 300 gr. solids with 76.0 of H-4350 and got 2497 fps with a 24" barrel.
