Good morning, Chris.

My recommendation is to get a scale before doing any reloading. They are cheap and last a lifetime. (Well, I bought mine in the late 1960s and it is still accurate - checked against a digital scale).

You should be able to pick up a scale at any shop that sells reloading equipment. If you will be in an area for a week or so, Amazon sells digital scales for under $20. (Later you can get a beam scale.)

I have used the Lee scoops for light loads and they seem fairly accurate but I do always double check using a scale.

Load data for rooks seems to be all over the place. If I find my Colin book, I will let you know what he says (I moved a number of books into a storage area).

My exoerience with a 295 rook is that I was getting very high velocity using the loads recommended. However, thatmay just be the rook rifle I was using.

Best success with your rook.
