Got this info using H4350 in my CZ 550 from Geoff MacDonald at Woodleigh. It worked on my rifle. I recommend you contact him to double check unless someone else on the board can confirm.

Your loads are very much in line with ours:-
375 H&H 350gr RN or PP SN
Federal 215 primer
68-72 grains H4350 for 2300-2380 fps.
For FMJ start at 68 grains and work up if required.
Regards,
Geoff McDonald.

Hi, I've bought 100 of your 350g PPs and 50 of your 350g solids for my CZ 550 in 375 H&H. My rifle is due in this week. The only load data I have is for Barnes 350g bullets. Do you have any suggested loads for the 350g bullets? I was thinking of using H4350. For 350g jacketed bullets Modern Reloading 2nd Edition by Richard Lee gives:

H4350 68g 2261 fps
H4350 72g 2432 fps

Thanks much,
Chuck


Regards,

Chuck
