Does it have to be either or Brian or could it be both?
I really do understand your well made point on practice and I imagine the Devils Advocate is at play but I think its worth asking..
The claim of one particular manufacturer is that you can drop an egg from 20m onto their 6mm sheet and it wont break...Gelmec I think...
Probably have too much time on my hands at the moment as I'm between projects but I think its worth a dabble..
Just rang them and they are kindly sending me some samples.Will try it out on some old rifles and see if it helps..just quick inserts..easily done..not much expense...
Also going to try bedding in Silkaflex 292...marine sealant designed for vibration absorption....why not have a go??
Thought I would ask on here first though...probably been tried by someone..
