Re: I'm back!

I just pulled one up on ebay. It says max velocity is 999m/s which is about 3277 fps. It also say max energy of 800 joules which is 590 ft/lbs. 3277 fps with an energy of 590ft/lbs is roughly 1.6 grain projectile? I am guessing more than 800ft/lbs on my rifle. Im not sure how there is a maximum ener...

Re: I'm back!

I have been curious about the barrel chronograph, but I am seeing the traditional style as low as $70 on ebay right now. I might just go ahead and order one... Maybe I'm just over thinking it but I have a tig welder and was thinking I would make something pretty. I'll definitely check out what you f...

Re: I'm back!

I usually shoot at 2000 psi. The pilot volume is almost non existent, so it opens with a sharp bang. I am currently figuring out how to go about attaching the sights. But honestly its fairly easy to aim as is. Although it would be cool to see the performance at 50-100 yards. I'd put this thing up ag...

Re: I'm back!

I'm shooting 360 grain slugs at the moment. At 1800 psi it shoots clean through 2" plywood. No hesitation at all. At 3000 I feel like it could drop a grizzly bear. A chronograph is pretty high up on my list but currently I dont have any actual number for performance.
