According to the proof tables in Greener's The Gun and its Developement the 4 bore used 279 gr of powder and a 2791gr ball as a service load. This apparently a conical since an 4 guage ball should weigh 1750.
In Chapter 26 he notes a 4 bore using 12-14 drams (up to 385 gr) and a 1510 gr spherical bullet. Though this comes out to a 6 bore ball.
The proof tables give loads for bores up to 1 but I doubt that bores over 4 were used in shoulder fired weapons. 4 bores were about as heavy as a man could handle in field shooting situations.
I am pretty confident the 4 bore is the most powerful BP catridge load. Using ME as a guide in guns of this sort is misleading as to its actual effect on game.

The .577 BPE was a very popular rifle at one time. Many thought it the 'cat's ass' for not only buffalo, but elephant at well, to 100 yards range. This info, from 'letters' to Field Magazine in Greener's book.
: Note that with our powders, the 160gr. charge of Harvey's #6 rifle powder in the .577 is equivalent to 192gr. of GOEX.
: Now apparently, Swiss powder 1-1/2F is supposed to duplicate the speed of Harvey's #6, but burns dryer, of course. Not being able to buy Swiss powder, I'll take Ross Seyfrid's word for it's use in duplicating regulation loads in British singles and doubles. Regulation in singles, means shooting to the factory sights. Regulation in doubles, of course, means shooting notonly to the sights, but both barrels into one group, or perhaps parallel, which would be perfect regulation.
; Ross's test of a 16 pound 8 bore rifle, and a 4 bore rifle are given in the July 2001 issue of Rifle Magazine.
; Recoil - 8 bore-16 pounds - 1,200gr. con. 1,450fps - 160 ft. lbs.
: Recoil - 4 bore-18 pounds - 1,285gr. RB - 1,500fps - 196 ft. lbs.
: Recoil - 4 bore-20 pounds - 1,800gr. con. 1,330fps - 212 ft. lbs.
: .577 NITRO EXPRESS - 13 pounds - 750gr. 2,050fps - 92 ft. lbs.
: I really have no desire to shoot a .57 Nitro, let alone an 8 bore, or 4 bore. Detached retinas don't seem worth the experience.
; I do have a friend with a 6 bore double percussion ball and shot gun, that regulates with a mere 150gr. 1F. That one, I'd probably shoot.

Bit late, sorry, but in response to:
".577x 3 1/4"......??? whats this? i have heard of the cordite round,but never the BPE round....."

empirevr:
Check on page 152-153 of Fleming's text, he lists 5 load combinations, with 160 or 167 gr BP and 560, 610, and 650gr lead bullets. Hoyem lists it on page 52 of his text, showing 4 patterns: the BP Express, the 'N-for-B', and two full nitro loads.

If you don't have these two books, I might recommend adding them to your library. They are pure gold as far as British Sporting cartridges are concerned.

"The History and Development of Small Arms Ammunition: Volume Three: British Sporting Rifle" by George A. Hoyem

"British Sporting Rifle Cartridges: a Summary of Case Types, Headstamps, Bullets and Charge Variations" by Bill Fleming
