Links from Quackenbush re anti airgun

[johncedarhill]

There are a couple of links on the yellow regarding anti airgun. The one I looked at was from South Africa. Implies intentional use of lubricants to raise velocity. I did get my copy of "the airgun from trigger to target" and read the first chapter on the "combustion" of fuels. The test gun did have leather seals and no mention is made of when the test in a "nitrogen" atmosphere was conducted. I wonder with new seals synthetic not leather if the test could be repeated with the same results.

Probably yes but that is a crazy idea putting lubricants in the combustion chamber. Unless you just want to distroy the air gun and get another one to distroy.. Most everyone knows that puting any low combustable petrolium product in the combustion area of an air gun will raise the velocity, at least until the seal burns up and or the spring breaks, not to mention the other parts in the action..

The article is anti airgun and anti gun because the velocity can be raised using petroleum etc.

My post was not clear. I mixed two topics. I just really meant to post the link which discusses the addition of combustibles to increase velocity thereby making them more like a firearm not an airgun. It claims to be a scientific journal. Perhaps they got the idea from Cardew. Cardew maintained that much of the velocity was due to cumbustion. The test for the combustion was done in a plastic bag in a nitrogen atmosphere where the velocity dropped by a significant amount. After returning to normal cycling in air the velocity returned. Cardew concluded that much of the velocity was due to combustion and not just the spring. The test gun had leather seals. I was wondering how a new gun with synthetic seals would compare in this sort of test.

The article uses this combustion and dieseling for anti gun purposes.

I did not mean to suggest that combustibles should be added to the gun. I should not have been in a hurry when I posted.
