Sinclair Comparator Nut No.1
- This ogive gauge tool is used to help measure the actual “ogive touch” for regular bullets (Tangent ogive shape)
- Works well enough with deep seated bullets if measuring with bullets seated.
- A good alternative to the Sinclair inserts which do not suit short bullets deep seated.
- This “Nut No1” does cailbres 22, 6mm, 25, 26, 7mm and 30. (NB: The other product called Nut No.2 fits 17, 20, 27, 30, 33cal)
