I learned about shooting from practical positions when I went to a shooting competition. I thought I had it locked up. I could tear the 10 ring out of a target with my Bisley, FROM A BENCH!! Standing there on the line with 20 other guys, forced to shoot offhand, I embarrassed myself. I shot just about everything BUT the 10 ring.
Can I say I didn't take it well??
1000 rounds later, not a one shot off the bench, I feel that I'm a bit better shot now. I try to shoot from practical postitions. Kneeing is a quick postion to assume and is quite steady for me. I've also done some practice resting my hands and forearms on something, usually the rack or fender of my ATV as it's the closest thing. That always helps.
Another part of my problem is that I was forced to recently change my grip style. I used to cross my thumbs behind the gun, left over right. A few of the HEAVY rounds let me know that that WASN'T going to work out. I've reposotioned my left hand with the thumb forward and the index finger around the trigger guard. IT HELPS! No more blood.
