In a rifle, about 150 yards.
Depends on the rifle. For a .22 LR, about 150 meters. For an M-16, about 400 meters. For a .50 Barrett, about 1800 meters.
The .22 LR is effective to 150 yd (140 m), though practical ranges tend to be less. After 150 yd, the ballistics of the round are such that it will be difficult to compensate for the large "drop".
I believe it means it is a 10 round .22 caliber long range rifle.
In excess of 1.5 miles
150-300
Does not exist. However, a 22 LR does and it would be in the 10-500 USD range.
No. The case of a 22 WMR is longer than that of a 22 lr, so the cartridge won't fit in a rifle that is chambered for 22 lr.
Bullet weight is immaterial. If it is chambered for 22 LR, then any 22 LR load is fine.
10-225 USD or so
Depending on the distance, yes. At close range, definitely yes.
The weapon can fire 22 short, long or long rifle.
The mini-mag should still be .22 LR.
