Hello,
For my 7mm08, I'm switching from Hornady cases to Lapua cases. The Hornady case holds 56.9gr of water and the Lapua case holds 53.9gr of water.
If my pet load in the Hornady case is 47.3gr of powder (published max is 48.4gr), what should I load in Lapua case to duplicate it? I know it may not be as accurate as the Hornady case load I was using, but I figure it is a good place to start.
Does this look right?
53.9/56.9=.9472
.9472x47.3=44.8. new load is 44.8?
Back off 1- 1.5 grains. Current load is using 83% case fill. -1.5 grains in new brass would be 84% case fill. Should be close.
