I want to replace my 12-ga loader and have been researching the Spolar. Many of you have posted positive and negative comments on the Spolar and I appreciate your candor. I found a video on U-Tube, I've pasted the link below, of a guy from Texas demonstrating how to load on a Spolar. Now to the question; what is that God awful buzzing sound when the press is in the full up stroke position? And what is its usefulness.
