I would recommend (if very new to reloading) to get the abc's of reloading! I have the 8th edition, it was great learning material when I started reloaded 4-5 years ago! The author talks about everything under the sun in that book! From. Equipment, safety to benches and powders and on.
Personally I've had no problems with any hornady gear and there data shouldnt get you in any trouble even on the warm side of the scale. Provided you remember when reloading any NEW LOAD! Always work your load up! Start at the bottom of powder and try! Then look for pressure signs on your cases light flat primers or split/ting cases. Have fun.
Also just an interesting fact . When hand loading your firearm can be much more accurate with a colder load. Or maybe a middle of the road load? They are all different!
