H-870 is the number you’re asking about or at least that’s my assumption. H-1000 & Retumbo should be close, at least to relative burn rate. Too many variables for me to give an exact correlation. As you likely know, H-870 was the slowest burn rate powder some decades ago. IMR 8133 may also be close to what you’re looking for. Always consult and follow powder manufacturers reloading data.
