I picked up a SxS 410 shotgun for Chrismas. Due to the non existence of 410 ammo on the store shelves, I have resorted to CBC brass 2.5" brass shot shells and 9.3x74R brass for 3" shells. The 100 each that I purchased should last the remainder of my time left here. I say this cause I've done alot of patterning and experimenting trying to raise my scores. You get 1 good reload from a factory shell, after that, the strength of the crimp gets weak and your pattern shrinks about 2" each reload. I couldn't break a 90+ average without shooting factory new shells in competition.
I shot alot of 410 when I shot skeet competently so I know my way around a 2.5" 410 shell. Generally, the 410 is considered a 20-30 yard gun. There is a diminished return trying to stretch the killing power of the 410 further because of the small 1/2oz payload space in a 2.5" shell. Try to go to larger shot = less pellets in the pattern. There is a balance and 7.5 is about as large as you can go in a 2.5 shell.
3" shells are a different animal with the additional payload space.
While getting ready to start experimenting with loads for 3" shells, I found the TSS rabbit hole on a turkey hunting forum.
These guys are getting 100 pellet 10 inch patterns at 40 yards with a 410 using #9 and #10 size TSS shit. TSS is speedy but it is pretty impressive.
Material Properties:
Steel shot weighs about 7.5 grams per cubic centimeter (g/cc) and is harder than lead.
Lead shot weighs about 10.6 g/cc and is a relatively soft metal, deforms easily and is reasonably gentle on a gun barrel.
Hevi-Shot weighs about 12 g/cc and is a mixture of tungsten, nickel and steel and is a much harder metal than lead. It can damage the inside of the barrel of a shotgun and therefore must be loaded with thicker shot wads for more barrel protection.
Hevi-13 weighs about 13g/cc but is otherwise similar to regular Hevi-Shot.
Federal Heavy Weight weighs about 15.2 g/cc and has a higher percentage of tungsten in the metal which makes it heavier than the previously mentioned materials.
TSS weighs about 18 g/cc and has the highest percentage of tungsten of any shot available today and is therefore the heaviest shot currently available. It is an extremely hard material and requires even more precautions than the others to protect the shotgun from damage.
TSS comes in three densities, 13 (hevishot), 15 & 18
Non-toxic shot has come a long way. Good luck on the hunt!
This breaks it down very thoroughly. It would have saved me an hour or two of digging at the least if I had access to it a couple of weeks ago 😅
Lots of great info there. If you Google TSS or Hevishot pellet count you will find tables thatlist the pellet count per ounce from steel all the way up through TSS. That will give you an idea how shooting smaller pellets in the heavy stuff gives you a higher pellet count advantage.
