Will, don't get confused with the modern rifle that is made by a company calling itself "Henry" they even imply in their ads that they have some connection to the original 1860 Henry. There is none.
The Henry that we refer to on this forum is either the originals or the Uberti made replica, which is what most of us shoot.
The other "Henry", which they call the Bigboy, was deemed to be legal for SASS matches. This came after several years of debate and where the members in straw votes kept voting it out. However in NCOWS where we try to recapture the 19th century experience it is not approved since it is an exact copy of a rifle that never existed in the Old West
.
What we refer to as the "improved" Henry is the Winchester model 66. It was the first rifle bearing the Winchester name and the first with a side loading gate.
Some of us really dislike the henry Bigboy and feel that their advertisements are misleading.
I hope this clears this up some for you. You certainly are welcome to ask as many questions as you like and we will be happy to answer them to the best of our ability.
