That entirely depends on your gun as far as the accuracy goes. A rule of thumb that I have found is this:

The fastest burning powder that fills the case with your chosen bullet weight will usually be the most consistant (accurate).

That being said, I think Reloader 19 might be a little to fast for the 7mm for bullets that weigh 160 grains or more, but fine for bullets less than 160 grains. H1000 would be better for bullets heavier than 140 grains in the 7mm.

Reloader 19 should work very well with most all of the bullet weights available for your 270 Winchester, H1000 should be pretty good with bullets over 130 grains.

Reloader 19 should be just ok in your 300WSM, and H1000 is probably too slow burning to work well for most bullet weights in your 300WSM.

You won't know how good they work until you try them. Hit the bench my friend!
