Here are some pics of my Cummins B3 that I tuned myself, and a shot of a group of 6 that I shot today at 75 feet. Sorry it took me so ling to get this up here for you AirRifleGuy, been busy. I need to find a muzzle break badly to hide that horrablyugly turned down area where I removed the hooded front sight. Its an el-cheapo gun ($20) with a cheap Daisey Powerline 3-9x32 scope on it, Leupold rings, polished internals, my own style of synthetic seal retrofit, and replaced the mainspring. Not bad for the little bit of money I have invested in it.

TexasTweeter,

That'll do very nicely.

You are sure having a lot of fun with a $20 gun! Your tweaks are "on the money" with a great group like that. I'd still like to see some chron numbers- just curious what it's producing.

Too bad we are not closer I'd let you shoot the Greydigger I stared at through my scope for 10 seconds before I decided it was a stick, lowered the gun and of course it moved and went straight down the hatch!

I took a walk came back and waited on him. Bi-pod, my back against a tree at 25 yards. He poked out, looked straight at me, I had him fullscreen in the scope, released the safety and he went back down- he beat my a$$ but I know where he lives.
 
My father has just challanged me against his sheradan. gonna be a two part test. Part one, target shooting in his back yard. Part two grakel shooting in his back yard along with various other trash birds... I dont think he will know what hit him. I may have him break out his chrono,a dn we shoot over it during the target part of his so called challange. He has been talking some smack about out shooting my .22-250 with his .25-06 too, but he has been shooting the same winchester model 70 for over 20 years, so I have a feeling that he might have his handloads a bit more dialed in than mine... Is that a deent group for an air rifle at that range? especiall taking into consideration the lack of money and knowledge i have on the rifle? this is all jsut fun and games to me, have I stumbled onto something?

TexasTweeter,

you da man.

Sorry to bug yo about the chrono. I only chroned one gun (ever) and it was boring as piss.

I neeed to do it again on my .22 so I can get better with mil-dot usage. These airguns aren't exactly a .223 so you have to choose zeros carefully.
 
chrono shouldn't be that boreing, set it up so that you are shooting through it during target practice or sighting in, and shoot through it as normal. a decent chrono should keep the information for you to go over later.
