A friend of mine had one years ago we used to shoot. I found it to me mild recoiling, compared to a Model 29, but extremely accurate. A very big gun for small hands. They've always been pricey to shoot, unless you reload. That box of converted .308's probably has quite a bit of collector's value, as do the original boxes of Normas.
Several years ago, I acquired a Wildey in .475 Wildey Magnum. I managed to find a box of ammo for it and when I went to shoot it I was afraid of the recoil. It's so big & heavy, but has the gas operated system, so recoil was very manageable and extremely accurate, but again, TOO big for small hands. I ran out of ammo before I could get really good with it!

Not practical or economical for me, so I sold it.
