I use the internet and double check against what my reloading books show. Load information etc change over the years even with the same companies.

Buy a few new ones, pick up a few old ones, and look at the .com. Take notes and verify...
Actually between HERE and Handloader is where I get my most up to date info. And still verify...

are you planning on using sierra bullets for the majority of your reloading? if you're not, i would suggest you go after the mfg's reloading manual for the bullets you're gonna use most of the time for your first manual in your library.
i only mention this because even within a specific weight and caliber - lets say 150gr 308 bullets - no two bullets are going to be the same length or shape. heck - even among hornady bullets alone there are 7 different bullets in that caliber and weight.... and and 3 different recommended COAL's among them.
and while you can use another manufacturers' data as a starting point for powder in a similar class bullet, having a baseline where teh appropriate COAL is for that load is going to be helpful in more ways than 1.
1) case fill % - a short stubby bullet and a long skinny bullet loaded to the same COAL will sit a different ammount in the case. max charges for these two bullets, if both loaded to the same COAL will be quite different and would likely result in one of the two loads being WAY over pressure and potentially into the realm of dangerous.
2) how the bullet sits in the chamber in relation to contact with the rifling. Being jammed into the lands with the bearing surface if using data from another bullet can also cause unsafe pressures when it happens in an uncontrolled fashion.
this is why its critical that any time you change a component from the published data for that bullet that you do a proper load development to ensure that the load you're attempting to use is both safe and accurate in your firearm. doesnt matter if we're talking about powder, primer, bullet or even the brand/headstamp of brass. heck even the firearm can come into play with that too.
always remember - safety first! reloading is a wonderful hobby, but its not forgiving for the careless OR the reckless
