I would echo some of the above opinions. Know what you are reloading. That means reload your own brass. Inspect everything before you reload it. Look over your brass, primers, powder, bullets, etc. Throw away anything that is not 100% right. If you want to shoot lead bullets, buy a aftermarket, button rifled barrel, such as a
KKM or a broach cut
Lone Wolf.
Load reasonable rounds using information from reliable sources (read that "established manuals). Don't be in a hurry to load those +P rounds. You may find that shooting less powerful loads is more to your liking!
Lastly, know that ammo from any source can go KABOOM! The only round that I have ever experienced exploding personally was a factory round. Wear protective clothing at the range: eye protection, a hat and a heavy long sleeve shirt or canvas coat is a good idea along with appropriate hearing protection.
