Weights I don't know, but the Micky has a 22" Shilen #4.
It's the only one I had built
The Brown has a 24" Shilen (I think), maybe a factory profile.
The Banser I bought as a barreled action, 23 " Lilja, another slim profile
The Micky is the heaviest, Brown next, then the Banser.
I'd say the barrels have more to do with that than the stocks.
The mickey is the most accurate, most likely because I had the 'smith build it specifically for the 210 Nosler, all it's ever shot.
Sorry to not provide more info, but I'm not a real rifle Looney, I just hang around the edges of the group.
