Hodgdon's Reloading Data Center

I'm still new to the world of reloading, but I think the answer is that yes they are both safe but they burn differently. One may generate pressure faster than another, or may require higher chamber pressure to fully burn, etc. Different compounds plus different physical characteristics (shape, density, etc) means they are different creatures entirely that just happen to do the same thing in the end :)

I'm just getting started in reloading, I've been shooting for seven years at this point. I'm just about ready to reload my first few rounds, but I'd like to clear up some confusion first.

I have Lyman's 49th edition reloading manual, and when I compare some of the loads on this site with the ones in the book for the same bullet, I find that some of the powder measures are significantly different. (3.5 grains vs 4.7 for the starting load using Winchester 231 powder on a 115 grain bullet).

This fills me with concern, and leads me to ask two questions:

1. Are they both safe to use?
2. Why such a difference?

I've always gone with hodgdons load info for their powders, and used the Lyman for other brands of powders.

Either one is safe, but I guess Lyman got more lawyers. What's the max charge for the same load?

He is talking about the same powder and bullet weight.
 
Hi all,

just getting a start at reloading .45 ACP, I'm looking for a press, 550B Dillon a buddy will sell me the dies and toolhead.

Case prep gear, possibly an all in one vertical set up like the Hornady, is Hornady the only maker of this type of set up?

Any leads on this would be greatly appreciated.

Boing_Snap, you may want to start a new thread for your questions rather then repurposing (hijacking) this one.
 
For the most part their published loads are significantly lower than any other published data from the competition. Take it for what it's worth & always use caution.
 
Warning to .264 Winchester Magnum owners using the Hodgdon Loading Data from the internet.

If you look up the .264 Win Mag Load Data here the load data for H4831 powder (and possibly others) and the 140 grain bullets, and 160 grain bullets are simply wrong. I believe they have interchanged the loading for the two bullets and as a result the 160 grains are way overloaded, and the 140 grains are way underloaded. I wrote to Hodgdon a few years ago, but the data remains unchanged, wrong, and DANGEROUS!

And if you think only overloads are dangerous, here is what happened to my .264 WM cases when I loaded some to Hodgdon's recommended minimum load for 4831 and a 140 grain bullet. They imploded! I think the pressure was not high enough to seal the neck, and pressure on the outside of the body collapsed the body of the case.

Using Varget and Hornady match 30 cal 178gr BTHP
Hornady doesnt list reload data at all
And this hogdon site recommends 41gr varget starting point for 180gr bullet, and 42gr varget starting point for 175gr bullet.
So i presume with my 178gr bullet i start around let's say 41.6?
 
Thanks for the confirmation, i imagine i bump up until one of these situations is reached.
Drop in accuracy, max load on chart (think its around 45gr) or pressure signs.
In 308, are first pressure signs seen in the shot primer?
