    Just about out of W-W brass but I have a good supply of Federal which was shot in this gun. Does anyone know how much difference there is in case capacity? Should I just start load development over?

    I do not know, but my 270's both shoot better with resized 30-06 brass. I'll have to ook and see if I have any 270 brass in WW and Fed that I can test.

    Easy to find out ... put a spent primer in each case, add water, weigh.

    Haven't done it in 270, but every other caliber I've done it in (changing from Win to Fed brass) has required a pretty large change in the load (4 grains less in 308). Federal brass doesn't seem to have the same head hardness, or it really does make a lot more pressure. Either way, I would back way down to the starting load and work up toward your current load just for safety sake. Depending on how hot your current load is, I would sincerely dobt that you'll get to it without pressure signs.

    Thanks for your info. My present loads are STOUT. So I think I will just chunk the brass and start anew.
