I did try a brick and had nothing but stovepiping ftf.
Later I found that my trouble was a trigger shield that I had installed to keep trigger group clean. The feeding round lightly bumped the shield and would cause jams regularly.
Never tried the ammo again as I found the federals to be cheap, dependable and accurate enough.
Another ammo that I really like is Aguilla 22lr pistol match. It does shoot better than the federal and uses eley primer. Last time I bought is was $2.20 for a box of 50 at Natchez.com.
