Bismuth/Tss Duplex Pattern Test

[Ruggedsportsmen]

Wanted to show you guys this pattern. A lot of people say bismuth cannot be duplexed with TSS because the hard pellets will deform or fracture the bismuth. This was not the case in my experience. What we have here is a 28 gauge buffered 3/4 ounce published bismuth load traveling 1375fps. I replaced 1/4 of the bismuth with TSS 9.5. I only had bismuth #6(equivalent to #4 steel) so thats what I used here. I run bismuth #5 in this duplex now. Pellet count is around 218 with 118 bis 6 and 100 tss 9.5 or 190 with bis #5s. The only way I could get this load to pattern nicely is TSS on bottom and bismuth on top. With the bismuth on top I am still able to add buffer which I think prevents the bismuth from fracturing. Also, this load likes to be choked tight. As you can tell from the first photo the IC is too wide. Switching to an IM made for a really bitchen pattern. This was shot at 30 yards. You could probably run a mod choke and have a nice decoying load but I usually run everything just a tad tighter than most.

How did you take up the space that the 1/4 oz of TSS shot created in the 3/4 oz Bismuth load?

Wow that looks great. I’d offer even with the IC it’s a drt pattern. The IC pattern just looks a little left. Thanks for sharing.

My bad I forgot to add I used a 410 nitro card

Was a pretty gusty day. I was surprised it only moved the little that it did. I mostly jump shooting rivers so thats why I lean towards a tighter pattern.
