Edd , I seen Wyatt's boxes that won't load from the top properly. You would have to push the loaded round forward towards the chamber. Then slide it back into the box.The option was loading them from the bottom. I did not like either option. I know you can adjust the feed lips to help. I have 3 Wyatt's boxes and they load from the top too. No problems with them.What do you mean on making sure it feeds properly, problems are you seeing when instwhat alled?
I also have had the spring replaced to help with feeding.
