Hello, I own a 1/4 inch slide valve set combined with a QEV and would like to build or find an optimized semi-automatic loader to use with 1/4 inch steel balls. Any suggestions on what type of loader would be suitable? What should I look out for to ensure the loader operates reliably and does not jam the balls? Thanks.

You could look at making a blow-forward bolt which uses the air from the main valve to operate. You can probably see how it works in this animation from clide or this project.
