Re: Help - 30-06 and 215 Hybrid
Normal load development, testing both seating depth and powder charge, usually requires fewer than 50 rounds to complete. You have plenty of bullets under normal circumstances. With the Hybrids, it has been my experience that it is not even necessary to tune them for seating depth, so the round count for load development is even lower.
I would recommend that you seat your bullets so that the base of the bullet is even with the bottom of the case neck or seat them to mag length (depending on your rifle and what COAL will feed properly). Then, do your powder charge workup with whatever powder you have chosen (I would bet that RL-17 would work really well for this combination).
With a single trip to the range and an expenditure of 25 rounds or less, you should have a load that is tuned to your rifle.
Even if someone else lets you copy their homework, I seriously doubt that you will have better results or fire fewer rounds trying to make someone else's load work in your rifle.
