H4198 versus Reloder 7

[Billy]

I found the thread on "H4198 vs N120" very useful. Would you gents in the know be kind enough to provide the pros and cons of H4198 versus Reloder 7? I've bought a few pounds of each and have some test loads ready for my .45 PacNor, but anything to shorten the learning curve would be appreciated.
Thanks,
Billy

Sabotless in the .45 with a 275gr BE, they both give similar velocities and accuracy at near the same charge weights. With 250's, #7 was not as accurate or as efficient for me but maybe I did not go high enough in charge weight.

Being a double based powder, #7 should be better for ignition.
