Doc,
I use an Oring pick for an Oring pick Seriously there are tools called Oring picks that are used just for this. Mine has a double bend. Here is one set that should work fine. Mine are really old. http://www.google.com/products/catalog? ... ps-sellers
When you get them check out the tips to make sure they are very smooth. 600 or 1000 grit sandpaper works well to smooth them if need be. I've found that getting the Orings in is a bugger unless you have something in the chamber to push back up with. I use a 3/16 wood dowel sanded smooth and inserted from the muzzle. I push the oring in so that one end of it goes into the groove. The rest of it will fold over and head down the bore. You can use the dowel to push it back up and it will usually pop in at that point with a little help. Grease it before you insert it, and make sure the groove is clean.
