You know why they think my accuracy is too good to be true? Because very few people bother to test under the same conditions that I do. Find me someone that has been working on long-range shooting technique as long as I have, sets up the shots under the same circumstances, and, most importantly, maintains their guns like I do, and then you'll see better accuracy. My accuracy results are not the results you'll get on average, for a number of reasons.
I've discussed this before, but the short story is that I set up my shots to get the absolute best possible performance, since I also do a lot of airsoft target shooting.
Want to duplicate my results? First, the setup. You need an indoor area with NO wind where you can take long range shots, measured from the sandbag to the target.
You next need to work on the rifle. It needs to be completely cleaned out with a non-abrasive cleaning solution, and you need to pay special attention to the trigger, so that the break is as clean and consistent as possible. Almost nobody does this, and it makes about a 1/4" difference in groupings at 100 feet, generally. You also need to wash the hopup bucking, and clean the barrel thoroughly. I clean every inch of my rifle, lubing the cylinder inside and out, and make sure my rubber parts are still in good shape. I clean the barrel out thoroughly, make sure they're still polished well, then leave a micro-thin layer of lube in the barrel. It has to be as consistent a layer as possible. Not cleaning the barrel and hopup can make up to a 3" difference in groupings at range. Once your rifle is completely cleaned out, it's time to zero the scope.
Third, you need to spend a good long time zeroing your hopup for the range and type of bb's. Use only clean, new, high quality bb's. I only use AE because those have the best consistency.
Getting the consistency of the sandbag right is less important in airsoft than in RS, but you don't want it too hard or soft, since you're trying to reduce vibration.
Once you've got your rifle set up, you can fire your shots. This is the other place where groupings start becoming really different. There are a number of different things that make the difference here. You can't just pick up a rifle out of the box and expect to shoot it well. You have to familiarize yourself with the rifle. I spend many hours making sure that I know the exact feel of the rifle, so I can get the same stock weld every time. I practice cocking the rifle with a coin on the top of the scope, so I can do it smoothly. I work on breath control, and I use my adductor muscles to control the vibration when the piston is moving forward. Finally, I have to stroke the trigger just right. Even the slightest jerk can throw the grouping off significantly. When I'm shooting my accuracy groupings, it's after I've already fired at least 500 rounds through the rifle zeroing and testing, and I'm quite familiar with the rifle.
Duplicate all of that, and you'll be a lot more likely to get results like mine. But nobody does, so they end up with wider groupings, and then accuse me of lying. It's no skin off my back, they're just missing out on a great gun. But if they took the time to duplicate the process, then they would see different results (and get better in skirmishes also). That clear things up for you?
