It seems this is a bad time to be shooting and looking for ammo period. Looking forward to this passing

I load 18.6 grains of RD with 1 1/8 ounce shot in a SP-10 and of course with enough red beans to fill in . I load that in REM and Cheddite hulls . That’s a powder puff load so personally for myself I wouldn’t be afraid to try whatever bushing I’m using for RD with the IMR Red .

Thanks! Is this a 2 7/8” load? My Lifter has 2 5/8” chambers, if this is a powder puff load in 2 7/8” would it still be a powder puff load in 2 5/8”? And do you know the PSI for your load? I didn’t see any red dot loads in the spreadsheet that use less than 20 or 21 grains of powder.

I am trying to find a 1 1/8oz or 1oz load to use with some of the powder, cheddite hulls and versalite (SP10 equiv?) components I have. I can use beans or punch my own cardboard for filler too.

That’s a powder puff load in a 12 gauge . Yes I only load 2 7/8” .

That RedDot/1-1/8oz load is pretty much the standard extra light 10 ga load. I use it. One thing that always concerned me is the use of things like red beans, rice etc as filler. I have never seen any numbers where these loads were tested with and without the natural fillers. Looking at the available data, even 1/8 ozof shot can have a not insignificant effect on pressure. If you weigh the amount of red beans/ for instance, it takes to fill the hull, it may have a significant impact. Unlike a light cork cushion wad, the beans actually have a lot of space which the shot occupies, so it takes more than you would guess to really fill the shell. I don't remember the numbers, but I loaded a hull normally and added enough beans mixed with the shot to get the proper length and the combined weight of the beans sdplus shot surprised me. Be nice if someone loading these would have them pressured tested against a shell with a cushion wad filler and a simple shorter shell with the base load.

Comparing 1 1/8 ounce 12ga loads with a Federal Gold Medal hull 19 + or - grains of Red Dot and IMR Red produce very similar pressures from what I see in the Hodgdon and Alliant online manuals. Both were around 10,000 psi.

The larger the gauge the lower the pressure. A 19 grain Red Dot loading was tested by member here and the pressure was about 6700 psi. I would expect similar pressure from 19 grain IMR Red.

If your concerned have the load tested. Personally I would shoot a 1 1/8 ounce 19 grain IMR Red loading, my tens have rather stout barrels and I am long since past believing composite barrels could blow up with "normal" loads. Good luck.

I too am way past the don't shoot in the Damascus or twist barrel stage....I have more guns with composite barrels than steel ones....charlie

I've been loading Longshot in the short 10 with good success. 30 gr. under an SP-10 wad. Had some tested using a 16 ga. fiber wad as filler and an OSC, 1 1/4 #8, 1225 fps and under 6K pressure.

Dug these out, waiting on some others to be tested. Longshot because I have some! Shooting these in an EH Damascus 30".

Now….if I only had some longshot.

Loaded up the following to hopefully try today:

(A) 20.7gn Universal, 1oz #8, cheddite 2 5/8”, cheddite primer, versalite wad (SP-10 compatible?), with a cheerio or two, roll crimped

(B) 19gn IMR Red, 1 1/8oz #8, cheddite 2 5/8”, cheddite primer, versalite wad (SP-10 compatible?), with 2 cheerios, roll crimped
