Very heavy, but that's probably just right for a .458 Lott. I had a .375; it shot great, but was too heavy and bulky to suit me.
The only thing I wasn't too keen on was the metal strap that is used for the recoil lug. The lug takes it's purchase in the fore end, the strap engaging a small steel projection under the action, where the lug should be. It works OK, though.
FWIW, the smaller caliber RSMs are different, in both the size and in the lug arrangement (they engage as other Rugers do w/ a lug under the front receiver ring); these I like, have one in .338 and 30/06.
