I really like the Wilson case trimmer. You can inside neck ream to get rid of donuts. I have the rcbs trimmer with plates but wouldn't work with 338 Norma.
I had an old Winchester 300 mag and an old Browning 12 GA auto loader with a 32 inch barrel. I loaned a cousin some money on them and he begged me to buy them back. As soon as he got them back he took them to the pawn shop. I was dumb.
I ended up using 77.5 grains of H1000 with the 210 berger. I switched to the 215 bergers and with reloader 26 was using 74.5 grains . When accuracy fell off I worked up a load again and ended up at 75.5 grains of reloader 26. This rifle has around 600 rounds through it .
