I'm looking to reload ammo for my .338 WinMag for whitetail hunting in PA. I want to try reloading some lighter loads using H4350 powder and the 185 grain Barnes TSX. The Lee guide has me doing 62 grain for 2727 fps. From the research I've done my bullets should still expand at velocities as low as 1600-1800fps. Anyone have data on how much powder to use? I'm looking at hitting as close to 1800fps as possible.
I'm fairly new to reloading and for the past year have been sticking to the book. I tried doing some rough calculations for a place to start and came up with 46.0 grains (which seemed low). I took two Lee data sets and ran some calculations:
62.0gns ~ 2727fps (62/2727*2000(fps)=45.4)
68.5gns ~ 2971fps (68.5/2971*2000(fps)=46.1)
I used 2000fps rather than 1800 because I didn't want to underload. Is this a system that would work if I tread cautiously? Any thoughts?
Thanks for your help.
