Why rework the later action ?
other than strength wouldn,t it be easier to find a Lee Speed - Lee Enfield - action & rework that !
or are these harder to find & or more expensive ?
I ask as I have just had a Lee Speed in my hands and liked it a lot & have now found a cheap Lee Enfield 1892 rifle ,also a Lee Speed action !

Thanks for the great tips and photos , but wish I hadn,t seen them now LOL
