A friend got me on to this site. I live in extreme northern California. I've hand loaded since my dad taught me back in the late 60's. Things have changed a lot over that time. I'm now shooting a browning a-bolt 300 WSM. Here is where I need help. I shooting 168 vld bullets with 66.8 grains of rl-19 winchester cases and cci magnum primers.I get one hole three shot groups at 100 yards. Things look great until I checked speed. It's shooting at 2680 and should be somewhere around 3000. I'm concerned about long range tragectory. Any thoughts?
