Most rifle shooting match rules include a minimum trigger pull weight.  Here in the US, the Civilian Marksmanship Program (CMP) Rules state that the trigger weight cannot be less than 3.5 lbs for the Vintage Military Rifle and are measured at all major CMP matches.  

I had worked the trigger pull on my No. 4 I shoot in matches down to less than 4 lbs and didn’t want to trust the spring scale I have, so I made up this “Redneck Trigger Pull Scale”.  The weights are bullet casting alloy ingots and some .577 Snider cast bullets.  


3 lbs 12 3/4 oz held.

Mk II upgrade includes a piece of tubing over the chord so that it doesn’t drag on the trigger guard.  That lowered the weight an ounce...still above the 3 lb 8 oz minimum...

i love the way we rednecks solve problems and thats a great example - im sure someone will comment n the pulley principle of that string doubled over rather than a straight vertical pull , but i like it ,

I set this up to measure the pull on my AR.  The Rules call for a minimum pull of 4.5 lbs and my Wheeler trigger gage was showing it right on the line of 4.5, so I needed something more accurate. 



Not much margin to spare, it’s 4 lbs 9 3/4 oz.
