reduced slug loads in 20 gauge

[mickbr]

Hi folks, not much out there on reduced slug loads in shotguns. I was wondering if anyone has any data or or links on this subject. I'd like to load down below subsonic level in 20ga with some slugs for fun. I dont mind working all the way down to mousefart levels in pistol cartridges. Shotguns though are a different kettle of fish, would rather find some sources of information . If anyone has loaded slugs at low speed would be interested to hear.

Here is some reduced load data for 12 and 20 gauge. You might be able substitute a slug for the shot.

Hoping it helps.

Ajay, always enjoy reading your stuff....but do you have and light slug loads for 20ga 2-3/4" casings? My old RB shotgun only has the short chamber. Thanks!

Thanks, the data is 1150fps so I could safely drop a couple grains to get subsonic I am thinking.

Ajay thanks, but I was chasing subsonic loads and hoping to go about 1/3 the weight of powders you are using. If you have anything along those lines, very interested to hear.

It's not rocket science. Find a listed load with Red- or Green Dot, maybe Unique for a similar payload, and reduce the load gradually from there. If you have a chronograph you can plot the grains/velocity and extrapolate even more loads. When chasing light loads, fast shotgun powders is the way to go as they responds well to reduced loads. The worst than can happen is a partial blooper. You can often tell when the load is becoming too weak, as the smoke will have a "sweet" smell to it, and you'll have flakes of unburned powder in the barrel.
