Powder question (reloading)

[BTLowry]

is there a dependable website or book that lists what powders interchange or how they relate to each other?

IE I see IMR4350 and H4350 on a reloading data table. One is for 110gr bullets and other is 130gr. Almost identical starting powder charges.

Before I get a lecture, I know to follow books and not just throw any powder available in a case

I would just like to know if there are certain powders that have the same characteristics. ie is 4350 the same from any manufacturer?

Refer to the burn rate charts

+1 on burn rate charts. Powders with similar burn rates should perform about the same.

Burn rate charts as stated above should help out!

Some powders are the exact same. I haven't heard that about H4350 and IMR 4350. Here are some that are

HP38=231
H110=296
HS6=540
HS7=571
WAP=Silhouette

Hogden power is less tempeture sensitive than alot of other powers.

IMR 4350 and H4350 are very similiar, but not the same. IIRC, the IMR can be a touch faster in some applications. Some other powders that are the same though, are H 414 and W 760.

X3 on the burn rate charts. Then factor in volume
