I'm not sure where I'm going with this post, but here goes. My 1995 Hodgdon 26th edition manual has .303 British load data for 215 gr. I realize powders have changed properties, etc since then so I did a little comparison with old data vs the latest electronic Hodgdon data available. The latest electronic data didn't list 215's, so I compared 180's.

I'm not sure where I'm going with this post, but here goes. My 1995 Hodgdon 26th edition manual has .303 British load data for 215 gr. I realize powders have changed properties, etc since then so I did a little comparison with old data vs the latest electronic Hodgdon data available. The latest electronic data didn't list 215's, so I compared 180's.
The old manual recommended four different powders, but I compared only two: H335 and H4350. All listed are maximum suggested loads, and non appear to approach 45,000 cup.
- H4350... old data; 46gr 2333 ft/sec. New data; 48 gr 2500 ft/sec.
- H335... old data; 41 gr 2323 ft/sec. New data; 39 gr 2449 ft/sec.
Old data lists H4350 for 215 gr projectile max load @ 43 gr 2090 ft/sec. H335 for the same 215 gr projectile max load @ 39 gr 2047 ft/sec.
Please don't use this info as load safe! It is just for information as there seems to be some interest (me included) in perhaps developing a load for the 215 Woodleigh. Thanks!
