Shotgun bullets for big game | J&G Brenneke | Wild boar hunting with shotgun

Are bullet cartridges suitable for hunting big game? What is its effectiveness and reach?
12-70 caliber shotgun shells usually weigh between 28 and 39 grams, reaching speeds of over 400 m/s and at close range they release a large amount of kinetic energy, being as effective or more than any of the rifles we are used to. see in our monterías. But the problem is that the weapons that are commonly used have limitations when it comes to specifying the shot and therefore its effectiveness and range.
Imagine the stopping and penetrating ability of a 600 grain projectile. Would you use it to hunt wild boar in short positions? Certainly, because there could be nothing more appropriate for the instant arrest of a running deer or wild boar at distances of less than 50 m.
This is exactly what the 39 grams of J&G Brenneke bullets represent, offering great expanding and penetrating power, being fast and effective. Undoubtedly ideal for hunting big game with a shotgun at short and medium distance.
