Lots of good information here and some that should be taken with a grain of salt.
I pick up brass at the range, lots of high rollers who do not have time to reload use the clubs ranges. One can spot brass that is past it's experitation date with a bent paper clip and a good cleaning.
I do the powder drop and install the bullet and seat right then before going to a different case. No cases get a double charge that way. I'm old and slow and have all my body parts still.
Load well away in a scary part of the homestead from the family. You can sit on the couch for hours and hours twiddling your thumbs and no one says boo to you. Turn on the TV, Start reading,listening to the radio or start reloading then they (wife and kids) have all types of junk they need you for. If they can't see you all is well.
Keep plenty of loading blocks on hand so you can keep all cleaned and ready to go brass handy when you start reloading.
MAKE SURE YOU CLEAN AND INSPECT EVERY PIECE OF BRASS YOU ARE GOING TO RELOAD. Then inspect it again after you have reloaded it.
Want advice on the load for your 7 mm mag? Buy several reloading manual and do your own work up never trust a word of mouth or printed on a forum load. Typeing errors happen every day on the internet. Remember the thing in school to pass the message along to your neighbor and the end result was nothing like the orginal message?
Do you own work up and be safe.
I started reloading so long ago powder came in wax papper cans and kegs. Primers came in waxed cartons too. Herters was a bigger outdoor product supplier than Cabelas is today.
I keep records of my reloads and have Remington brass for the 243 and 308 that have been thru the press 20 plus times. Ya like me they are old and slow and accrite.
