Like you, I run a few head over 20 at any given time. This set up works well for me. Excuse my drawing as it is not to scale, but should illustrate the concept. My chute has swinging doors on either side, so if I do not want the cow to load out, I can cut it back into the corral, or cut it out into the larger catch lot from the other side of chute. I back my trailer right up to the posts labeled load out. So, to answer your question, I absolutely load from my working chute. After the head gate on the chute, I have a 7 ft run leading up to the load out. Works well for my purposes and I can work cattle by myself if need be.
