Well I am starting to like this site! it's full of good information and I hate to bother everyone but I need to ask anohter question, I need to find a good brass catcher to save my window and keep my legs from getting burnt while shooting pasture maggots, any good suggestions?

Go to 3bucc.com they have good catchers.  Or you could go to brownells and do a search for the company "3bucc" they have it there also.  I don't like the DPMS ones that wrap around the handguard.  After a certain number of rounds (20 or so) the bag starts to sag causing the cases to hit the wire frame on the catcher and bounce back into the ejection port.  

You wanna know what I use?

I beer can case holder...you know, the one the 4 6 packs come in.  I'm assuming you're sitting down to shoot?  Well, just put this to the right of your rifle, slap a range bag on the lower side to anchor it, and you're done.  

Mine never fails to promote smiles at the range.  

The cheapest honest-to-God one I've seen is $20, and I've seen others for $40 that were pretty much the same thing.  I think the chepie one is in the current CDNN catalog....you might have a look there.  

btw...why is there a window anywhere near where you're shooting, and what's a "pasture maggot".  Ground hog??
