Phil,

I shoot a great 450/400 3 1/4" NE Double made by Charles
Lancaster in 1911. It shoots like a dream (1 1/2" groups
@ 50 yds). I plan on taking it to Africa this Summer after
Cape Buffalo & have no reservations about its ability to
handle dangerous game. Who knows, maybe elephant in 2006?
If you are going to get into reloading I would get a
copy of "Shooting the British Double Rifle" by Graeme
Wright. It's very informative & gives a variety of
cordite to modern powder conversions. My 450/400 seems
to regulate better with Reloader-15 rather than IMR 4831,
but I guess each gun will behave differently. Good luck
with the Hollis. Jim
