Well, you know when I read something like “Oh, I’ve changed my mind to buy L2 since I’ve watched that video…” I am really happy that I will not have among my clients persons who is so narrow minded and thrashing about having now idea of what it is about. I prefer them to drill the mind of the other manufacturer
I like to work with people able to think and consider the facts, not emotions.
So, I’ve watched that video as well. Have no intention to discuss the ability to shoot, scopes, weather and so on. I just want to point out some significant facts, from my point of view.
Based on my experience while changing the pellets the shooter should clean the barrel, then lead it with the new pellets and only after that try to group it.
Based on my experience every pellet with every gun has so called “sweet spot” , some barrels allow it to be in a wild range of dozens and dozens m/sec, some only in a small range. To shoot different pellets from one barrel without even trying to find the right speed… Well, to me that is inappropriate from the point of view of making conclusions.
The following from above said it that the speed of the pellets should equal the length of the barrel. No problem to speed it up, but it can be done at the regimes far away to be optimal. Overconsumption of the air and my worse accuracy than it can be. So for 350 mm barrel the speed about 290 m/sec that is too much. If the shooter wants more energy he should use heavier pellet, not faster speed. Or increase the length of the barrel.
To me those three is more than enough. If you have different opinion, welcome to discuss, but as I told in the beginning I prefer to avoid the discussions lead by emotions not by facts.
