That doesn't sound too far off really. Also how far out are you seating the bullets. Pressure tends to go down as you seat the bullet further in the case.
"Let glorious acts more glorious acts inspire,
And catch from breast to breast the noble fire!
On valour's side the odds of combat lie,
The brave live glorious, or lamented die;" - Iliad, Book V
