When you go get your loc-tite make sure the label says Thread locker or Blue 242. It will hold your nuts and bolts in place against vibration and still be able to break loose with steady even pressure without breaking anything.
Get some cheap surplus hardball .223 ammo and shoot at 100 yards, it will shoot good enough to gain your skills and won't break the bank doing it. After you have experimented with other bullet weights you will find the one your gun likes best but for right now just get good so you can tell the difference.
Lose the bipod and get some sandbags or a Caldwell sandbag rest to hold your gun in place for the best shooting. You will be surprised at the difference it makes. Use the bipod after you get good and you are out in the field taking those 200 yard shots at ground squirrels.
Once you are on target you only think about one thing. Imagine your cross hair is attached to your trigger and when you squeeze the trigger you are pulling the cross hair back towards you because it is attached to the trigger. Your only job is to keep that cross hair centered on your target no matter how hard or easy it is to pull back the trigger, no matter how far you have to pull the trigger back, concentrate on the cross hair. The shot will catch you by surprise because your concentration is not on the trigger and your groups will show it.
Use the same exact technique when you are shooting a gun with iron sights, handgun or rifle makes no difference, open sights or aperture sights makes no difference, concentration is on that sight and the sight is part of the trigger. Silly little trick but it works.
