There are so many companies producing excellent presses and accessories. I started back in the late 70’s with a RCBS Rock Chucker press, dies, scale, and all the trimmings. I also bought most of the reloading data books; Lyman, Speer, Hornady, etc... and worked up my loads. I make 20 to a batch and then test them at the range for accuracy.
I keep detailed notes on powder charge, primer mfg and group size. I also keep control of the brass and make sure I have a note card that stays with the cases that lets me know how many times the cases have been fired.
I have since moved up to a Dillon 550 press so I can speed up the process.
For rifle cases I use a full length sizing die and I always buy Carbide dies for my pistol rounds. I pretty much stick with RCBS dies but have a couple sets of Lee dies that work well.
I am very careful with my powder charges/weights and can honestly say I have never had a misfire or dud (I have had a handful of factory ammo misfire) and once I get the right powder charge and bullet combination the accuracy is better than any store bought ammo I have used. Then again, I have never purchased the really expensive match ammo that is out there but I have never felt the need to spend that much cash when the ammo I reload suits me fine.
I keep my Glock 19 cleaned and oiled regularly and after every trip to the range. Yet after firing about 50-100 rounds, I find that I get frequent jams (1 per 15 rounds) with (only) Winchester ammo. I don’t buy it anymore. I don’t have that issue with any other brand. So, I will definitely not be reloading any Winchester.
