group size

Welcome to the forum jeep4. We shoot 10 shots keep the best 3 this is our group size.
Just kidding. I use a benchrest. Slow fire 5 rounds at 100 yds. using the best form I can. Then draw a straight line thru the 2 furtherst shots, using calipers, along this line measure center to center. I fire a minium of 5 groups of 5, measuring each, then average. The results I always state avg. group size, but for bragging purposes I will state my Best group size. after I give my avg.
The BR guys say if you can't keep your fingers on the barrel for 30 sec, ya need to let it cool. For the mini its about 5 shots. It works for me.

Hey Jeep, like cajungeo said keep the barrel cool. A hot barrel has move. I try to shoot 5 shots 10 to 15 min. Keeping the barrel at a constant temp. (WARM) A few of my buddies take a temp gauge to shoot at the same temp every shot. Maybe getting a little carried away, but it has its points. It is sooo easy to shoot a semi-auto too fast. Take several guns with you to past the time for cooling. Group size measurements are as cajungeo noted. Make sure that your gun is set real good on what ever type of rest you use, that means that when your hands and shoulder are positioned, looking through the sites there is no (repeat NO movement) of the target. If you can't get still learn to control your breathing and time shot with your heartbeat. Practice makes perfect.......shoot em up.

Jeep, there are many ways to stablize your riffle, just need to experiment and see what works best for you. I use two bags, place the bags at the action side of the fore stock and just behind my trigger hand, the butt to my shoulder. I am actually shooting as if free standing. Some guys don't grip the fore stock and use that hand to cup under the butt of the riffle. You see that alot with bi-pods or adjustable rests. After you shoot reposition your riffle back to where you started. Usually having to move the gun forward and set back down. Just gonna have to see what work best for you. You can also check the internet for target shooting techniques.
Good luck!

Hey jeep. My rest has a forestock stop, so each shot is fired from exactly the same spot, also the same spot with the rear bag. Consistancy is the absolute Key for accurate shooting. When I use sand bags, or bipods I put my left fist under the butt. By squeezing my fist I can raise or lower the muzzle for fine adjustments. Do like BullseyeBilly sugested there is a lot of Marksmanship techniques, on the net. Benchrest shooters, have made it a science.
I check out mods, or reloads, by eliminating as much of the human error as possible. When I'm satisfied with what my rifle, and ammo can do then I work on field shooting positions. Then I know its me not my equipment when I shoot poorly. Course then I could always blame a gust of wind.
