Jeeze, I had not even thought of doing something like this to solve my "I can't find buckshot" problem!
Is the powder load in high brass turkey load the same as in a buckshot load? If so, It should be possible to open the end of the turkey load and then refill it with buckshot.
Thanks, I'll just wait it out with 20 GA, 3", #4 turkey shot as my HD load. Better than birdshot #7-1/2!Wouldn't do that. Shotgun loading, unlike metallic cartridge loading, you work from and stick by recipes developed by the component and equipment manufacturers. There's no room for experimenting. Load with the exact components recommended and you're safe. Try a different wad, even, and the load ain't gonna be right. Also, I'd buffer a buckshot load, myself. The factory loads are buffered, works through the choke better.
