That always mystified me because it is too fast even for the Hornet except at reduced load levels.
It MIGHT be useful in reduced rifle loads (much like BlueDot) but I haven't done any tests in that use - and don't plan any as my supply isn't large enough. Plus, what good would it do to publish data for a powder that's been discontinued for 20 years?
630 is a great powder for specific applications. I scour old gun shops because my favorite 32 S&W Long loading uses 630. Out of a J Frame S&W I can safely push the 115gn FNHP cast bullet at almost 1100 FPS using published data.
Mr. Andrews sent me four pages of load data for 630 from an old Winchester load book. I want to sincerely thank him for going out of his way to do this. I would be happy to share any specific load data for pistol loads on request. He copied it and sent it to me via snail mail. Thanks very much.
Attached are a few pages that I photo'd from Propellant Profiles for the 630 and 630P. As noted in the articles both powders are primarily for high performance pistol cartridges. You could use the powder in a 270 cartridge BUT you would need to be exceedingly careful and have very guarded expectations. Using pistol powder in a rifle will give pistol results. If you seek rifle results you may as well make an appointment at the local hospital emergency room. In a 270 the 630 powder would be at maximum pressures when it had pushed a low resistance bullet of about 90 grains to a velocity of about 1200 fps. Unless you are well versed in burn characteristics of the powder to seek on-the-job training would be very destructive.
