Not a terribly popular rifle, so there were not a lot of them around. And it has been a while since I have seen one, so my recollector machine might not be working just right, but - I think you are talking about two different guns here.
Mr. Kelly is talking about one that is rather light.
and WH is talking about one that had either a 1 1/8 or a 1 1/4" barrel, forget which.. Neither one would be rather light.
And something that burns about 180 grains of Fffg??? Ufda!!!
Now, there is nothing that says you need to burn that much powder in it, so it doesn't need to buck an snort and such, but you're gonna have to do it at least once, maybe more.
I had one geez, I don't know, maybe 35 or 40 years ago, and it didn't feel like any lightweight, I'll tell you. And IIRC, it didn't kick like a feather, either.
IIRC again, I don't think that Forgett shot an elephant with it, but I think it was a hippo, which is still a lot of critter. I forget exactly what the bullet was all about, but I think it was somewhere in the 650 or 700 grain range, which is going to add to the recoil somewhat as well.
It seems to me that Navy Arms did put out a sporterized Zouave, but the details have faded a lot in the intervening years.
