most ithaca made field guns that have passed thru my hands are typically lighter than other american made guns...as such, it just seems like a good idea to use light loads in these old guns, in order to help preserve the old wood...plus, any pre ww2 made gun should probably only be fired with light loads, in an effort to keep the old, dried out or often oil soaked wood from cracking...

keep it simple and keep it safe...
