Hidalgo, if one comes on here expecting to find good advice and cannot determine if that advice is accurate and don't know the difference of exactly the same and similar, but not the same...he has no business with messing with powders and bullets in the first place...he should buy his ammo off the shelf and when he has gained a workable knowledge of what he is about to undertake, then maby take up reloading. I see your point of telling someone that these powders are similar and someone thinking that "oh, yea they are almost the same so I will load by the numbers that should work because they are ABOUT the same"...but like others have been saying for years on here and many other reloading sites....if you are about to undertake this hobby you better read some books, manuals, seek advice, know your firearms inside out, have pulled a few triggers before, maby shot store bought ammo and are not satisfied with what you are shooting..so I believe I will start reloading...well, if you are you better not take it lightly and understand that this is dangerous if all rules are not followed to the tee. Just like driving a car, these kids get behind the wheel at 15-16 yrs. and some of them are dead before they get started...why?..because they did not take the advice of the instructors, read some manuals, seek some good advice, and my car is capable of going real fast and I can handle it, impress my peers with my new wheels, etc. Other words, like anything else in life they jumped into it before they were prepared and that is exactly what gets all of us in trouble to begin with...you have to start slow and proceed with caution in anything you do...including this. Thanks for the comments.
