Bad time to start reloading 10 gauge?

Thanks Pete! Now….how daring do I want to be trying a Red Dot recipe with IMR Red? Wonder if Blue Dot can be swapped for IMR Blue?

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” .

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.
