Mine's not too bad, COL for the .900" long 440gr Cast Performance would be 2.28" to the lands, that only leaves the bullet seated .230" in the case. I have some 500gr custom bullets that are 1.05" long, to the lands, they're seated to the cannelure .450" deep, so I'd say 700gr bullets, unless they're bore riders, will take up a lot of powder room.
Of course, you could have the throat reamed to allow full powder capacity with less pressure, have done that with my .45-70s.
