@Jon222, I've had some real stinkers in my hands over the past 5 years of shooting air guns as an adult. Guns with triggers that practically needed a crowbar to lever them back far enough to fire, pellets that were only vaguely round and skirted and had the flight characteristics of a Meadowlark, spring piston actions that when fired sounded like the Hee Haw orchestra tuning up their banjos and singin' saws; I've struggled with all of these things as I poked about the cheap end of the air gun market. It was only when I found AGN and began to learn about ballistic coefficients, barrel crowns, o-ring issues, moly grease, and so many more critical topics in airgunning that I realized that not all of my accuracy issues were my own. Once that truth sank in, I began looking for ways to find improvement, even at the cheap end of the market. Trigger fixes for Crosman rifles, better lubing for any piston system, discovering which pellets my guns "like" best, use of the Artillery Hold... lots of stuff I'd never considered or heard of in spite of being around the shooting sports since Boy Scouts in my youth.
The most important thing I learned here on AGN is not to make someone else's level of performance the standard for me. I love watching Si Pittaway and Davey Thomas of VerminHuntersTV on YouTube as they shoot their way through Britain's pests and small game. But I can't replicate Si's brilliant shooting or Davey's skill in gunsmithing. Instead I take what clues I can and work to translate them to my $80 Walmart break barrel shooting CPHPs and Hatsan Supremes. As I see incremental improvement in my shooting I take heart and look for more clues to continue the trend. That, I think, is the best advice I can give anyone getting into airgunning: just get started with what you have to hand and make incremental improvement your goal. Believe me, I cringe now when I think about how excited I was to actually hit a gallon milk jug at 50 yards using a magnum springer. Yet that excitement back then is part of why I now challenge myself with 1" bottle tops at 50 yards with a spring rifle. Build strength upon strength and skill upon skill, all the while celebrating the incremental improvements, and leave the irredeemable junk in the past.
