BP and PR both seem to be out of Red Dot.
What would be a good substitute?

FWIW Alliant has put production of Red Dot , Green Dot , Blue Dot and Unique on hold for awhile .

FYI, Sparky will have Red Dot, Green Dot and Blue Dot for sale at our shoot here at Rock Mountain in July.

To those of you using the BP1044 wad, have you had any squib loads? It is reported to be undersized compared to the SP10. One commercial maker of 10ga loads told me he puts a X10X under them for that reason. I found that easy to do with 3.5" loading of bismuth, but in 2 7/8" loadings I stick with the SP10.

I'm just getting ready to load for 2 7/8" and emailed Ballistic Products about the same issue. They called me and I talked with one of their reloading/ballistics data reps. I was told that the BP1044 wad is a copy of a European wad (not Gualandi) and they bought the molds and design to make it. They made changes to the plastic used and slight changes to the design. He said the gas seal diameter is the same as the SP10 (I measure .002" smaller on the BP1044). He said they worked with RST on the wad and that they still use it. He said powder migration is just the nature of the beast and really became a concern with clear hulls when people could see the components. With enough vibration you can make it happen. Ballistic Products was very nice and receptive with the concern and he said they stand behind their products with repeated testing and R&D. He also said he is writing an article for the LC Smith Journal on reloading 10 gauge 2 7/8".

I spoke with Lisa of RST today at Rock Mountain about their 10 gauge offerings and the wads they use. She said they use Gualandi wads and will not be producing anymore 10 gauge for the rest of the year.

Glad I started reloading the short 10.

Beyond Morris on Thursday and Saturday there was only one other RST rep at the Northern/Rock Mountain and her name is Chris = Office and Sales Manager. Ernie Hausmann is recovering from knee surgery and was along with Morris. Nice to see and talk with all.

You are correct Frank. I misspoke. Her name is Chris. Sorry for the confusion

It sounds like a good option to help fill the 2 7/8" hull for 1 1/8 ounce loads in the BP1044.

I shot a bunch of 1044 wads last week at Rock Mountain and I had no squibs or odd sounding shots. I’m unsure how the x10x wad would work in 27/8” hull, and I’m sure it would raise psi but I’d not venture a guess how much

19.2 grains of Red Dot is a 32 bushing.
21.7 grains of WSH is a 22 bushing.
That seems like a significant difference in volume.
Also, that BP-1044 fits more loosely in a Cheddite hull than any other hull/wad combination I have ever loaded.
