If your getting chased off a police dog, try not to run through a tunnel then onto a small see-saw then through a ring of fire. They are trained for that!

Well I had some left over 28mm pipe and decded i would make a barrel for one of my guns. I decided to put it on this gun as i wanted to keep the rifle likeness and breech loading of my other gun.

I did have a 28-22mm reducer, but lucky for me 22mm solder-ring fitting are a PERFECT fit for 28mm pipe so I soldered that in.

The gun should have gained 20m/s and (because of the heavier ammo).

Because the barrel have alot more volume, being twice as long and wider, I couldn't use the same chamber so I extended it to twice its length, thats why there a coupling in the middle of it.

It dose seem alot more powerful and it go alot further and alot more recoil.

I have made a super cool ammo and put the old chambers end cap with a bit of pipe attached then put penny and glue in to it, I plan to film it when it destroys some things and will post here.

Unfortunately i didn't have any large jubilee clips so for now it will have to stay with insulation tape.

Here is another thousand words.
