I like the stock designs on the 70's and 80's made rifles. I don't think there is a lot of difference in function but many including current production are just too fat. Many from the 50's and 60's were as well.
I like straight stocks too. The one on the left is a 2005 rifle in 35 Rem. Notice how much thicker the forend is.
Marlin and Winchester, both made in 1958. The forend on this Marlin is as trim as the Winchester
