How To Measure Trigger Pull Weight

Thread Status:: Not open for further replies.

I've adapted my Rem 700 trigger, but I'd like to ensure it's not too light. Is at that place whatsoever way to do this without a trigger pull scale?
slam the bolt and hit the butt to make certain it doesn't "fire". numbers are a reassurance, however, yous need to accept control. though my target rifles are in ounces, my hunting rifles are between two-2 ane/2 lbs. a good jump calibration can be had from a science shop for less than $ten.
If y'all take some weights of a known size y'all can brand your own. Bend upwards a piece of heavy wire so it hooks on the trigger on ane end and you can hang something on the other end. A coat hanger might be too flimsy, maybe something like copper tubing might work. UNLOAD THE RIFLE and close the bolt. Hold the burglarize muzzle up with the suspected weight attached only resting on the floor. Gently raise the rifle, don't jerk it, and see if it trips the trigger. Adjust weight accordingly. Don't have precise one or half pound weights? You volition have to become inventive. If you have admission to a scale that can read small weights (a bathroom scale isn't good plenty) you are set. Possibly large fishing sinkers? A milk jug and water will work if you can do the math. A gallon of water is 8.34 pounds and yous can go from there.
Did I mention UNLOAD THE RIFLE?
So in that location I was, in the garage late one night having just installed a new trigger mechanism in my 700 and wanting to give it a 2.5# pull. What should I use for weights...hmmm, there's an unopened 2.5# bag of marshmallows in the pantry...so I put it in a plastic (paper or plastic?) grocery bag, bent a brusque chunk of dress hanger to fit and did the adjustments. Slammed the barrel of the cocked (unloaded!!) rifle on the ground to brand certain information technology wouldn't fire and was finished.
A ii.v pounds of marshmallow trigger is <ahem> existent sweet.
dirt cheap calibration
Hook a piece of glaze hanger over the trigger, gun pointing upwardly. Then hang a plastic milk carton on the other terminate of the wire. Pour h2o into the jug until the trigger fires. Then weigh the jug (and coat hanger).

Do that a few times to make certain the weight is consistent. Information technology's accurate and inexpensive.

SD, what kind of scale are you lot using that gives you authentic 2 to v lb measurements? My bathroom calibration's accuracy is almost +- 2 lbs with readings starting at 10 lbs, my reloading scale is only good for a bit over an ounce, and I don't have a postal scale that's skillful for annihilation over 8 oz.
I utilise a fish weiging calibration, does an excelent job, merely you have to watch information technology real well to see where it breaks.
