I'm having some trouble with my browning semi-auto 22. cal long rifle. It has new springs and a new firing pin and is in very good condition. When I shoot it, it'll ejects the spent shell with no problem but jams when loading the second round. I have to manually pull back the breech and release it to push the round in completely. I've cleaned, oiled and inspected it and can't seem to find what I'm missing. Any help or advice to get me looking in the right direction would be greatly appreciated. Thank you.
