Our reloading log books have the features we felt were important. We have two sizes, the smaller size (LOG-1) measures 5-1/2 x 8-1/2 inch so it fits right in your loading box, our larger size (LOG-2) measures 8-1/2 x 11 inch. Both logbooks have space to record date, temperature, wind conditions, case, primer, powder, charge/setting, bullet, weight, style, OAL, number of shots, group size and observations. The larger size also has room to record chronograph information. The books are spiral bound and lay completely flat on your loading bench. There are 50 pages per book with room for over 300 different load recordings in the small book and room for over 650 recordings in the large book.
