this page offers interesting information from a top european World champion in several MLAIC disciplines.
http://www.avancarga.com/8_articulos/25/1_revolver/temas/18_replica/18_replica.htmhe is using now a Pedersoli, but he complains about softer steel on the frame, like evident marks on the frame where the cilinder rests, from continous shooting, softer steel (typical italian....
) in the trigger and mechanism, softer steel on barrels, and oversized grips that had to be filed for competition in the 2011 Finland european championship and weak hammer springs.
he says that it might well be a Uberti revolver with a better Pedersoli barrel, at twice the price, but shows no proof of it beyond finding just the same shooting marks on the frame in another Uberti revolver (see photos in link) from continous shooting. (lets nor forget that these World champions normally shoot their guns a lot, to the point of needing a new revolver every few years)
it seems that the HEGE 1858 revolver is highly appreciated for competition by top shooters thanks to the Lothar Walther barrels and the heat treatment in parts and frame.
I think I might be buying one also, as I need a new Remington.
Portuguese shooter Paulo Jorge, WORLD CHAMPION in Mariette ( MLAIC 25 meters bullseye black powder revolver,) discipline, in 2006, in Burdeax, France, uses a Hege army Match revolver and it seems that many top shooters do it too.
his pet load:
a mild 16 grains of SWISS N2, with a 32 long case full of semoline (these World champions never use wads, which prevents them from getting top accuracy results) and a 454 H & N german ball, with a minimum amount of Wonder lube 1000 grease over the ball (according to him, too much grease is no good for accuracy).
all the best
