Tried it, no good. The thing is when your using glue or silicone etc it already comes in its own tube, its then just placed in the chamber and the air pushes the bottom of the cartridge as it has a built in plunger.
There is no plunger in the glue/silicone guns you refer to so its no good, it doesnt push the paste down, it just spits it all over in pieces.
I have one of these with three nozzles that I cut to 14,18,22mm, pretty happy with it and pushes the dough out with ease, I just make the dough a little softer than usual by adding a little water to the mix after the eggs are kneaded in, and then lightly coat with semo before loading the sausage into the gun.
A light spray of vegetable oil on to your boilie table also helps. Cheers.
Happy bait making.

That one is fine, the one i bought had no 'plunger' if you know what i mean??? It simply relied on the hard base of the silicone/mastic/glue etc cartridge to push out the materials with the compressed air. The one you show is practically identical to the gardner deluxe model which i have, they are definately worth the money.
