Re: Shooting Technique -- horizontal stringing
After I posted that it occurred to me maybe I had been using the wrong words to Google. So I tried again.
Here is what Varmint Al has to say (although I do not understand why sandbags give one shape group and a front rest another.
TRIGGER CONTROL.... Ever wonder why benchrest shooters use triggers that have 2 ounce pulls, or less? Well, look at it this way. Let's assume the front of the rifle was fixed couldn't move. If while you were pulling the trigger, you just moved the rear of the rifle just 1/100th of an inch, you've just changed your POI about and 1.5 inches. JUST 1/00th OF AN INCH and you've just blown your group! So, it stands to reason, the more force you must exert on your trigger to release the sear, the more the rifle will move. I like to think of it this way. A two pound trigger requires half the force of a 4 pound trigger (32 oz Vs 64 oz). So, a 2 oz trigger requires 1/16th the force of a two pound trigger (2 oz vs. 32 oz)!
I can't tell you how many rifles have had amazing improvements in groups, just by changing to a competition trigger, or at least having it adjusted as low as you can get it. This is the first thing you should do to a rifle that you're expecting great things from. WARNING! Triggers are very touchy and sensitive mechanisms. If you are not sure what you are doing, have a gunsmith adjust your trigger and test it. <font color="red">
Now, test what your trigger pull is doing. You don't need ammo for this. I like to start with the gun cocked and the safety on just so you can see how much your crosshairs move when you pull on the trigger. Get set up like you're ready to shoot and aimed at the bull. Now squeeze the trigger, while keeping a very close eye on the bull and the crosshairs. Did the crosshairs move? Then expect it to move when you shoot for real. Now play around with different positions for your trigger hand and thumb. I'll bet you if you place your thumb on the side of the stock that you will get lateral movement when you pull the trigger. A better place to put your thumb is on top of the tang or not place it at all. Some benchrest shooters will place their thumb on the back of the trigger guard, and just squeeze thumb and trigger finger together to fire. </font> Whatever method you use, you should be able to exert enough force on your trigger be it 2 ounces or 2 pounds without causing the crosshairs to move on the bull. Practice this.
