New 10ga recipe w/ BP-1044wad
 

Since the SP-10 is no longer available I developed a new load using the available Ballistic Products BP-1044 wad,
10ga Cheddite Hull 2 7/8"
Cheddite 209
18 gr RedDot
BP-1044 plus four .125" 16ga nitro cards in the shot cup
1 1/8oz #7 1/2 lead
6 fold

Average Pressure: 7600psi
Average FPI: 1163

Craig, I am using almost the same load and it shoots great at clays.I drop 19 grains of red dot and insert a 16ga 1/2" fiber wad into the BP1044. Thanks for the fps and psi.info.

That’s kind of a Charlie load ! He used to say 19 grains with 1 1/8 ounce using an SP-10 . I picked the bushing closest to 19 and it dropped 18.6 and used it with SP-10’s and the Gualandi style . I however used red Mexican beans instead of card spacers .

Craig L: is there a particular reason why you used four card wads rather than a 1/2” cushion wad?

No it's just what I had 16ga card wads

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 have not had an issue with the BP1044 wad not obturating in the bore of my 10s. I’ve shot them through a Parker (.775) and a Scott (.760). They definitely fit loose(er) in my hulls but they must expand in the bore sufficiently

I’ve used the 1044 wad with no issues.

Morris Bakers daughter told me I think two years ago when they used new CheddarCheese hulls with the Gualandi wad that if loaded for awhile the powder would migrate around the wad . They arrived at this from carrying a couple flats in the back of a vehicle for a month or so . She also told me they loaded pre fired hulls and this problem didn’t occur any longer .

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.

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

What does the x10x do to pressure?
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.

I wonder if you were loading this in 2 5/8" hulls if you would need the filler at all...

I use a #20 bushing with WSH that’s supposed to be about 18.6 grains . Tried that charge with both hulls using both wads .

Hello, I am new to reloading 10ga but not reloading. Recently got a 1860 Parker Brothers 10 ga, bottom lock, that I love and want to shoot it more. Looking to shoot in the upcoming Fall Side by Side. But I am *really* struggling to find 10ga components - I knew it would be difficult but I had no idea! Reading through this thread I can get most of these components except the Red Dot; as noted Alliant will not have for a while.

Reading 6pt-Sika's post, I want to make sure I am understanding this, using WSH, 21.7 gr for this load. Is that right?

I load WSH a **lot** for my 12ga reloads and have plenty. Would be great if I could use this for a 10ga load.

From this thread, I am thinking the recipe would be:
10ga Cheddite Hull 2 7/8"
Cheddite 209
21.7 gr WSH (Winchester Super Handicap)
BP-1044 with one 16ga Fiber Cushion Filler Wad 1/2" in the shot cup
1 1/8oz #7 1/2 lead
6 fold crimp

I can get everything from BPI, just want to make sure I am reading this right.

Thanks,
Eddie

Using a MEC 600 jr, you can adjust the height of the shell with the bolt and different holes at the base. I use WSF, Clays, and even Unique with great results with the BP1044 wad. My 10 is a 2 5/8" chamber. I use the 3 1/2" Cheddite hulls trimmed to 2 5/8". You can trim them to your needs.

Although I don't see any Alliant Red Dot currently available on-line I do see both Ballistic Products and Precision Reloading have Alliant Promo in stock. Promo is essentially the same as Red Dot, they advertise it can have variations from lot to lot meaning you need to weigh a charge or two from each bottle or lot to be sure you are getting the desired number of grains. 19 grains of Promo or Red Dot will deliver the same velocity and pressure but each may require a different bushing. FWIW I have never encountered that in my own use and the bushing that delivered close to 19 grains of Red Dot delivered the same weight of Promo.

Thanks! I did not realize that about Promo and Red Dot. Good to know. Looking into now.

That is good advice about measuring the loads. I do not use bushings for my competition and "old gun" loads. I powder drop and measure each charge. Takes much longer but I guess that's the engineer in me (and once had a squib load in a tournament...). Thanks!

May be 2 5/8"!?
 

You may want to double check the chamber length. 2 5/8" was standard early on. Then someone may have lengthened them to to 2 7/8".

Nope not 21.7 I use the #20 bushing and the table says I think 18.6 grains I’ve never bothered to weigh it . Seems to me I used the same charge with 1 1/8 ounces and just changed the displacement wads a bit . I’ve done this loading for 1 or 1 1/8 in both Cheddar and REM hulls using SP-10 and the BPI only thing that changes is the displacement wads . And granted this is what I’ve done for myself I’m
Not advocating anyone use my data but it’s worked for me . Use at your own risk . I kinda work on the premise of it went thru a 12 gauge hole and the pressure wasn’t great going thru a larger 10 gauge hole it should be no greater than and most likely a bit less pressure wise . Now one day that might jump up and bite me but I kinda doubt it .

Always weigh the charges! Machining differences can cost you the firearm, your fingers, eyes, or even your life.
