Ive been shooting competitively for the past 30 years plus in both pistol and rifle or shotgun never had to hit a bird in the air. Last month at our 2 gun shoot we had many thrown targets to hit and shot horribly. I think I hit maybe 2 out of 20 ? Since this was unacceptable, I bought my self some birds and a hand held thrower and enlisted the help of my shooting partner that also couldn't hit a bird in the air to save his life ? I MADE him come to the range today for some practice. Prior to range time, I watched some you tube vids on shooting clays and learned about lead time, distance,followthru and slapping the trigger. The first 20 targets, I barely hit five, but then it started to click. The second box of ammo, the hits started to increase and by the end of my second box. I was able to hit 4 out of four and I was pretty jazzed.My shooting partner still sucked and couldn't hit squat and I sent him home to watch some you tube vids. Since my shotgun isn't the best for this,Mossburg maverick with a 18 inch barrel and no choke ? I learned to watch the thrower so I could pick up the bird flight angle quicker and since I have a short barrel and no choke, take my shot at about 35 yards. Further then that, the bird might move in flight from a weak pellet or I just didn't aim right. Either way, I had a whole lotta fun today. Question, from what Ive read? The Mossburg 500 barrels with its available chokes will fit my Maverick ?
