Re: hard to find .22lr ammo?
Havent tried champions, targetsportsusa (TSUSA) has a good vareity but not as wide as say CTD (cheaperthan...) Which will have your ellys and so forth. I should also note CTD is sold out on a lot of what they carry.
I recently bought a few variety boxes from TSUSA and my shipping came to $14.51 + .082¢ for insurance. A big messege warns you (several times in fact) that due to demand , they are back logged and estimate a few weeks to process you. As mentioned above, if you already know what you want for a bulk order item, you can take advantage of free shipping, by adding a bulk item to your order.
Anyway I hope my info helps you. Good luck and happy shooting, friend.
