I would put out a handfull of dog food on the ground and sit on the tractor. Range was 10-15ft. Stayed real still and within 3 min. one to three of those big nasty bastads was eating. hammer was back and I took real carefull aim, and if they were real close together I could get 2 sometimes 3 per shot.

My formula is Standard primers, 6gr Unique, thick cardboard, shot to fill, top with a light card board wad, or a plug of styrofoam. If using cardboard then"crimp" by running it through a seating die.

Shot about 2ft dia.pattern at 15 or so feet. The rifleing tends to create a "donut effect" if the range is too long.

Hope this helps. YMMV

Never have loaded rat shot myself.

Consider using a .22. If we're talking ranges in feet instead of yards you should be able to make the shot.

The ones with the cute names like "The JUDGE", "The Governor", etc.

My neighbor's son in law, who resides in a state with more liberal gun laws, brought one by here a year or two ago and it would pretty much vaporize the vipers. But again, I'm not trying to pulverize them just kill them. Besides it's more fun when you can improvise. And those .410 shells are expensive.

BTW I hear rumors that Taurus is developing a 28 ga. revolver.

When I posted that I thought that you might not be able to have one of those, and I forget that 1/2 the fun of these things is experimenting (within reason) with loads, etc.

28 gauge? Oh, my!
