this shotshell ammo is straight from The Bismuth Cartridge Company in England. If you’re not familiar, the original Bismuth is a step above Hevi and really excels in long range performance (40-50 yds) and is absolutely devastating on ducks/geese ... hits em like a truck. Bismuth can be shot in the same traditional barrels and chokes as lead ... does not damage classic/traditional shotgun barrels & chokes like Steel or Tungsten does. Of all the non-toxic options to steel, Bismuth is widely considered to be the highest performing alternative over the past 20-25 yrs. Expensive ammo but extremely lethal on waterfowl ... big birds look like they’ve been hit with a Turkey load. Simply awesome, devastating ammo ... a great load for younger hunters, females, seniors ... or anyone who may have a condition and is recoil sensitive. (no offense to anyone who may fall into that category)
I have 4 cases NIB left ... 10 boxes of 10 rds per case (100 shotshells). Initially offered to trade for other ammo but I’ve procured what I needed. Market trade-value (IF you can find original Bismuth) is ridiculous ... anywhere from $25 to over $40 per box. I have $15 per box ($150 per case) in this ammo and that’s what I’d like get out of it ... add $15 for shipping per case. If someone is interested in buying all 4 cases, I’ll foot the bill for shipping it to you (lower 48).
If I had a vintage 20 ga. chambered for 3 inch, I'd be making you an offer! Unfortunately a lot of the old damascus or early fluid steel guns (which also often had at least one full choke) were built with 2.5 or 2.75 inch chambers.
I actually found a pile of 3.5 inch 12 ga a few years ago stuffed with 1.5 oz bismuth per shell. Similar situation... almost all older 12 ga. had shorter chambers. So I offered the shop a bit less for all they had (the boxes had grown dusty), and they sold it to me. I've been cutting open the hulls ever since, harvesting the shot, and stuffing it into other hulls (mostly 16 and 20 ga.) keeping my old guns in service. And you are entirely correct... proper loads of bismuth SPANK birds, from waterfowl anywhere to Indian lands here in western MT where non-toxic is required for all species like pheasant.
