The news reader scrambled the order so I have re-posted it. Sorry about
that. ;-)

# I cannot tell you if the Weatherby Guide is still available. I got my copy
# some 35 years ago when I got my first Mark V. It was a .270 W. Magnum and
# it came with a set of RCBS dies.
# The ammo at that time was $72. for a box of 20 hence I got into reloading.

# Your question regarding the issue of breech pressures got me searching my
# various reloading data manuals. Not many of them even list the .460 WEA
# data. They all seem to stop at .458 WIN. Even the IMR freeloaders guide
# does not list .460 WEA data.
# I cannot find anywhere in the Weatherby Guide where it definitively
# states if the pressure data is in CUP or PSI it just lists it as "Avg.
# breech pressure." The entry goes as follows.
#
#Charge. 126grs Powder.
#4350 Bullet. 500gr Muzzle
#Velocity. 2707 AVG Breech Pressure.
