30+ with Remington, but I have very good headspace. Switched out both bolt bodies and bolt heads to obtain less than .068 headspace.

I load using new unfired bulk cases for first firing, not reloaded factory load cases. I also mark rims and rotate 180 degrees on second firing. This insures equal expansion all around.
Neck sized 2/3 the length of the neck to center the bullet to origin of rifling.
My favorite load is listed at near maximum pressure, but appears to generate far lower pressure than the data indicates. Expansion is smooth with no annular ringing of the case body. Annular rings from first firing are what cause short case life.
