Mick, according to Accurate Shooter.Com(http://accurateshooter.wordpress.com/2008/04/15/hodgdon-and-adi-powder-equivalents/) AR2206H is Hodgdon H-4895. This is from Handloader Magazine (Issue #216, Mar 2002)
Test rifle Win. 94 W/20" barrel,
Win. cases, Win LR primers,
165gr Oregon Trail flatnose bullets,
Hodgdon H-4895
21.0gr 1,403fps,
23.0gr 1,505fps,
I have loaded some 175gr cast bullets with 28.0gr of H-4895, but they are of a gascheck design and are sized(0.311") for my rifle. The hardness and bullet lube also come into play, but at least this will give you something with which to work. Another good load has been 30.0gr of H-4350(AR2209).
