A good single stage press for reloading rifle cartridges.
Lee Classic Cast
Hornady Lock and load
RCBS
Lyman Orange Crusher
there are lots of bench top presses out there.
The Lee is the best buy for your dollar.
If you dont want to dedicate table or bench top space, then I have used the Lee Hand Press for years now to reload everything from .22 Hornet to .357 Magnum to .30-06 and .375 H&H to .416 Rigby. You need a couple reloading manuals. Buy those and read them for techniques and steps. Then look into presses.
Lyman's 49th Ed. book is great as is the Sierra manual and Speer. Richard Lee's 2nd Ed is good too.
Try the search function or listing at the bottom of this page for more info as there are LOTS of threads on this question.
Welcome to reloading.
