Determining a safe load?
Ok, I have recently bought a sako 75 finnlight 300 WSM. I was surprised to see that it is a long action. I bought a full length magazine so I can run 200 grain accubonds seated close to the lands.
The max load for IMR 7828 in the book is 68 grains with an overall length of 2.860". With my bullets 0.020 off the lands my overall length is 3.100.
That leaves me 0.24 of extra case capacity. How can I safely determine a maximum load before heading to the range.
