I ventured down this road a few years back with 10gauge load options and bismuth.
initially, I wanted to repurpose the 400+ rounds of factory 10gauge federal hw15 turkey ammo. I made Loads with steel shot and bismuth shot with factory components, 52grain powder (federal factory), flight stopper wads, federal hull and primer. Steel results pattern well, and kill geese with steel 3’s, 2’s, 1’s, B’s.
Searching for advise on bismuth and the 10gauge, many on this forum and others, I moved away from the 10gauge bismuth load options. I will say 1.6oz of bis 1’s in a 3.5” 12gauge throws awesome patterns at 40yards.
I loaded a few Lyman’s 3.5” 12gauge 1.875oz bismuth 1’s loads as well. I’ll get around to shooting those soon. I did find good results and data with the original repurposing of federal components and using bismuth in 10gauge, the load was also a 1.875oz buffered load.
In testing Boss Bis 10’s, their pressures are around 12,300psi, at 2.0625oz, they offered bis 4’s, 2’s and 1’s. I think they more recently bumped up their payloads to 2.125oz, but did a limited run. I’ve found in my loading, sometimes less payload to be better.
regardless of overall payload, I routinely shoot 1.125oz of bismuth 4’s or #3.5’s in the 12gauge and can kill geese at 45yards. 1.5oz in 3” #2’s kills geese well, buddy used those to kill sandhill cranes and a swan this past season.
thanks for continuing the data on 10gauge options.
