A quick overview of the Benjamin Trail NP XL covering muzzle energy, artillery hold, long range accuracy, and night shooting.
Here's the scope I have on this rifle. [ Ссылка ] I've added it to the description because that question comes up a lot. The original scope was really good but whatever came loose rendered it useless so when the warranty replacement arrived I gave it to a friend. Here's a scope I have on another air rifle that I really like, but it costs almost as much as this rifle, so it just doesn't make sense at this level. [ Ссылка ]
Here's a calculator for muzzle energy. [ Ссылка ]
Here's a calculator for free fall.

Drop a 1 pound mass 1 foot and it generates 1 foot pound of momentum.
I can’t find any explanation describing that anywhere on the whole damn internet. Just formulas and calculators. All the formulas I’ve seen are in grains so I had to figure out what a grain is too.
7,000 grains = 1 pound
Free fall rate is 32 feet per second squared.
Knowing those 2 facts I worked the formula backwards starting with a 1 ft lb result and using a 7,000 grain projectile comes out to ~8~ feet per second which is the final speed of a 1 foot free fall.
