Likewise with Isopon..
Assuming it's not a micky take..
The fibreglass is hard and the plastercine will harden and dry out. The silksflex is designed to remain elastic and absorb vibration in very demanding environments and subject to huge stress variations, without splitting, drying out.
Open to further suggestions before I get the drill out..
It was tongue in cheek, ish.
The HW97KT stock is hollow, and I wanted to add some weight, plasticine seemed weighty and flexible enough to fit into the gaps in the forend without damaging the stock, I managed to squeeze in ~500g front and back.
A combination of filling hollow voids, and an increase in weight has resulted in a pleasant to shoot "out of the box" springer. Oh I've also added an additional silencer to move the balance forward to my taste.
