opinions on best reloader for the common rifle ammo??for lite to moderate activity
RCBS Rockchucker.
It is the standard to what others compare themselves to.
Do you need to spend that much to make good ammo? No, but it is the best or equal to the best single stage press's.
A good kit to get started like a RCBS partner
http://www.midwayusa.com/product/531246/rcbs-partner-single-stage-reloading-press-kit will get you started. Lee equipment is good, except for that scale. It is accurate, but S-L-O-W, it will drive you bat poop crazy in short order.
Whatever you do, get a "O" framed press.
Man cave, rt to left Rockchucker, Partner. Reloader spl, and a old turret press. I could do it all with one, but I like to leave the turret set up with 2 sets of straight walled pistol. The RS holds seating die for 06, I shoot a lot of 06, and the other two get whatever needs to be in there.

All will load any rifle or pistol/revolver ammo I shoot, 222, 223Rem, 30-06, 8mm Mauser, 6mm Lee Navy (if I can get brass) and...... you get the picture.
Most of my stuff was bought used. The Reloader Spl was my first, bought used 30 years ago and it was loading stuff for 600 yard matches.
