I'd alway use safety first when reloading, although, Hodgen lists 71-73c grains of H1000 behind a 110 grain Hornady projectile. It appears that cartridge is capable of holding large powder charges.
One of the very best sources for reloading data that I have found is the One Book / One caliber series of manuals. Online orders can be obtain at Loadbooks Bullet Reloading Manuals, Bullets, Reloading, Guns
or purchased at many sporting goods stores that handle reloading products. I have one of these manuals for each caliber I reload and trust their data as gospel. They go under the heading of "The Complete Reloading manual for the __________" etc,etc.
