Power - C:B

Many of us here are limited by the length of our barrels because of transportation issues but our chambers are generally not nearly as long as the barrel for obvious reasons. The generally accepted C:B is .8:1 but should one be limited by a certain length barrel; will making a larger chamber make it...

The stungun is 350KV, forgot the K. Dongfang: Im not sure about your second part applying for me because oxygen shouldnt affect whether the gun sparks. The first maybe be true because ive never checked for that. The problem is not getting the right mix of propane to air, i have that calculated out a...

Pat: When the stun gun sparks it has no problem igniting the mix and the sparks are set at about 1/8inch for each. Bob: I do have a fan and a ball valve for venting already but my question is, can the spent gasses actually interfere with sparking? That is almost what seems to be the problem because ...
