weighted gun and accuracy

[Sticky_Tape]

I had a thought and tested it on my new gun. The gun I used was a copper barrel sealer that is piloted by a ballvalve. Ballvalves that are used on a light gun throw off accuracy an annoying ammount.My gun is very front light. I thought why not add weight 1/4 way back from the front of the gun. This would add more inertia near the front of the gun making the gun less susceptable to the heavy jerking movement of ballvalve pilots. I tried this. The gun without the weight was very unaccurate and probably couldn't hit a 2L pop bottle from 30' with a barrel full of steel bb's. With a wieght the gun could land 30 steel bb's on 4''x7'' cardboard box at about 30'. I really suggest wieghting the end of your gun if it is very front light. Tell me what you think.

They use the same idea on compound bows to balance it out. All i do is rest the tip of the barrel against something solid (my .50 cal piston rifle is nearly 6 feet long and only weighs 1024grms) The only other way is to use a blow gun trigger i spose.

Yeah but ballvalves have higher flow and if you wanted to use high pressures or a compressor to fill your gun you would most probably have to use quick connects. You would have to use a quick connect ballvalve and a blowgun on the pilot assembly of you gun making you spend more mulla.

Numbers numbers. My cannon is just over 1m long and clocks in at 2kg.

What it's made of makes a big difference ^^


Still, mine is also quite back heavy, the QEV, most of the chamber and the pilot tubing is situated well behind the grip.


Whatever the cannon design, the more secure its position the more accurate it will be simply through reducing unwanted movement on firing. More mass is one way but using a bipod or even attaching it to a larger object to fire from would work too.

Unless you're shooting from an unsupported position, you ideally want a rifle that's as heavy as possible in terms of accuracy - take unlimited class benchrest riflesas an example.

I like the scope Jack, is that the kind of thing manufactures of ammo would use to test their stuff?

I would like to see someone shoot it from the hip!

Why not skip the BV altogether and get a levered globe valve.

You could have a blowgun piloted qev piloting the piston for cheaper than those valves you posted.

Not quite, it's more the kind of thing enthusiasts with deep pockets use to knock off a gnat's knacker from 2,000 yards

Meh....

I should find a way to bring in pics of our .50 BMG at work.

Gun weighs in at just over 600 pounds.... And its held to a 3,000 pound table using 1" bolts.

[damnit, double post again... WTF!]

All this for a 50 cal? I've guessing it doesn't quite need a recoil absorbtion system
