What boolit and load do you use? thanks!
Laser Cast makes a decent 170g .30 caliber hard cast bullet sized 0.310". I've fired several thousand of them with good results in my 1903 Springfields.
This website is a good starting point to develop light lead loads for 30-06. http://gmdr.com/lever/lowveldata.htm The chronograph data is close to the chronograph data I've collected over the years. I plan on using the 30-06 lead load data as a starting point when I buy a K31.
