If I'm paying $4000 for an airgun and it has machining and design issue, I'd probably be livid. Then again, that type of airgun is likely designed and marketed to some sort of high-level airgun competitor which is probably why I don't own one. As a hunter and leisure shooter, what is quoted in bold above is pretty similar to what I was thinking. It's pretty much what I expect out of the box with regulated PCPs, but at 25 yards. With or without a barrel cleaning, I expect to see decent groups at 25 yards with pellets from a PCP pellet rifle. After cleaning the barrel, groups should improve to what I would consider "good" to where it's not throwing flyers and most shots are touching. After tuning I expect to see similar groups at 50 yards. With an unregulated air rifle, ideally I'm expecting it to shoot consistently out to about 40-45 yards before having to make adjustments. But this is contingent upon having a rifle that has been well machined and assembled. If I want great groups, then this is where I would think of making several aftermarket purchases, modifications, and further adjustments.
On a high end airguns (let's say $1800 and up), I have a whole lot less tolerance for mistakes in design, machining, and assembly, especially after a thorough and fairly aggressive marketing campaign. Using customers as beta testers is a practice that I am
not a fan of. I will take time to tune an air rifle. I'm not the guy who wants to test barrels or have to devise ways to stiffen a barrel because of a design flaw. I think that if I'm redesigning your airgun, I may as well make my own of at least make it a habit of building "Frankenguns". I don't want to get too deep into this because I'm probably one of the least mechanically inclined members around here. With that said, I don't appreciate having to remove burrs from transfer ports and barrels on new rifles when I paid good money for the airgun. I believe that I'm paying for quality when I chose to upgrade to higher end guns and that's usually due to how they are marketed. I should be able to clean the barrel, maybe adjust the trigger, focus on finding favorable projectiles, and balancing the hammer spring tension and regulator (if if is an airgun with a hammer).
In sum, if I cannot clean the bore, scope the rifle, air up, sight in, and shoot good groups at 25 yards, your gun sucks (to me). If it shoots decent at 25, but I have serious problems with groups falling apart out to 50 yard after spending a reasonable amount of time trying to tune it before asking for help, I'm going to be looking to see if others have posted similar complaints. I'm no pro and I'm not highly competitive. To me, good groups are consistent with how my shooting patterns print overall. Regardless of how tight my groups can get across platforms, there are patterns to my targets due to my habits. I have a good idea of how they look which is often why you may read me stating in posts "don't take my shooting as a representation of what this platform is capable of. I'm not a great shot." Although there are some qualifiers, this is my take.
@Franklink, is this unrealistic to you?
