41fan,

I've been looking for a starting load for the 500 grain lasercast using IMR4895, H322 or RL7.  I know that H4895 is not the same as IMR4895, any suggestions?

Hodgedon's 4831 and imr's 4831 are too different, that's why the data isn't interchangeable. However, H4895 and IMR4895 are very close, the data is interchangeable.  When working up my load for my guidegun, I started at 43.0g and worked up carefully. Seat the bullet as far out as possible while still being able to work through the action. This is a compressed load. Just be ready for some recoil. doug
