Let us advice you to adopt another fascinating hobby -- Gun shooting !!
Rasul Allah (sm) had ordered all Muslims to learn Shooting... It is part of our deen.
Air Guns are fully legal and commonly available for all. Everyone must have a decent air gun to practice. Improve your aim to hit the target. It is great fun and great training...
Once you are fully trained on Simple airgun, you can later add telescope on airguns too.
Air guns are excellent weapons... you can hunt small birds, rabbits, for food. Practice target hitting techniques and later you can upgrade to proper rifles under army or expert supervision using the same techniques you have learnt on airguns..
One warning -- NEVER point the gun towards any person... these guns can be lethal or seriously injure a person. Always ask for safety tips before you start to practice. Always fire in clear open places or against mud walls or sand bags.. metal pallets can bounce off walls and hit someone. so be careful. NEVER target practice on birds, animals. This is great sin and Zulm.
In the picture, I am firing a .22 rifle but next to me is my Spanish GAMO 5.5 mm air gun with a telescope. Excellent for family, children and beginners to practice target shooting. Its fun for whole family....
Later, we will also advice you on building your survival bags for home, travel and cars... a Momin is always prepared..
