RiverWalker, you "can" use the rifle data for working up a load for your Contender, however it may not give the best results. If you're intent to use it, start low and work up slowly. You will not develop the same velocity in your 10/14" Contender as you would in a full length rifle barrel. You will also probably see unburnt powder as the shorter length barrel will probably not give enough time for a complete burn of the powder.

While your desired powder, 8208 XBR, may fall between the other two powders in the burn chart, it does not mean that it is ideal for this particular use. Powder manufacturers test many, many powder/charge level combinations for all calibers/bullet weights. Imagine the potential number of listings that each manufacturer might provide if they listed all their testing data. They only publish those powders that provide the best results across the board, with the least amount of liability (read: developed pressure).
