Rifled barrel vs. rifled slugs

[Bushpilot]

Here's some high speed of a Brenneke

Interesting... I figured if any slug had any chance of actually spinning to any degree at all, let alone enough to impart some stabilization, it would be a Brenneke... But no...

I've handloaded some of these which allegedly rotate due to the finned plastic base.

Without actually filming them in high speed (really wish I could afford one of those cameras) I can't tell if they actually spin, but twist marks in the ballistic media I fired them into do show some evidence of rotation.

Unfortunately, I have not yet been able to find a reasonably accurate load for them.

Both Brenneke and Foster slugs fly nose forward because that's where the weight is. The "rifling" has no effect other than to ease them through a choked barrel. My experience with both 12 and 20 gauge smooth bores has been that the right diameter round ball was more accurate and effective than any "rifled" slug. I have used .690 in a plastic shot column for 12 gauge and a .600 similarly loaded in the 20 gauge. Good accuracy and very lethal out to 75-80 yards. Rifling in the bore changes the whole dynamic.

The best way to go if you want a shotgun to be flexible with shot and have good accuracy with slugs is to buy a shotgun with interchangeable choke tubes for your shot using the more open improved cylinder for buck and get a rifled choke tube for sabot slugs.

A rifled barrel shotgun is specialized to shoot sabots. Here in Illinois we must use shotguns for deer, rifled shotguns are common, and give very good accuracy. 100 miles north in Wisconsin where rifles are legal, nobody has heard of them!! They are not suitable for an all around gun, get a smoothbore.
