The shotgun slugs and rifled slug barrels have become absolutely amazing over the past few years. Since the invention of sabot wrapped bullets, the ammo companies have come leaps and bounds. However, I believe that the sabot theory is still in its young stages. As the demand continues to go up for longer range shotguns, so does the research and development from gun and ammo manufactures. I understand that the shotguns shortcoming is one that is its greatest asset and that is bullet weight. Slugs effective range is greatly decreased because of the rate of drop the bullet incurs as a result of the heavy weight it is carrying down range and the deminished velocity that is needed to make an efficient and humane kill at extended distances.
With all that being said, I would not be surprised if what we one day see is a sabot cup designed to house a known long range bullet (i.e. .30 cal. 168 grain Nosler Ballistic Tipped). However, the sabot propelled from a rifled barrel with an insane twist rate, one that could get the bullet to stabilize. I know this sounds absolutely crazy, but it goes back to the premise, if you build it, consumers will pay for it. As we know, wooded areas to hunt are getting more and more scarce to hunt by the day. With that being said, the need to hunt more wide open fields that poses 250+ yard shots become more common, especially in shotgun only states. And for some reason, Game Managament personnel in these states stay true to the premise that shotguns do not have long range properties and dangers that rifles poses. Yes, it is time for them to wake up and smell the roses. Shotguns of today and the future are for REAL!
A good example of capabilities is years and years ago scientists sat down and studied the sport of drag racing. There findings came up with it to be virtually impossible for a human being to get in a car and drive it down a 1/4 mile drag strip with speeds any faster than 225mph. Well, turn on the tv, they are going 320+mph on a regular basis.
I am excited to watch the future of shotgunning unfold, and the limits continued to be pushed to what we think is beyond belief. Happy Hunting!
