Funnels...... I like most others, started out with a plastic RCBS do-it-all funnel. This morphed to the Saturn funnels....better in all regards, but caliber specific. Then Brad at Custom Reloading Tools (now defunct) brought out the most nifty, well-designed reloading funnel to ever come down the pike.
Manufactured on CNC equipment, all aluminum, it offered a funnel of the perfect size, caliber specific, used a screw-on 2" drop tube if wanted, and a series of exact caliber screw-on tips to perfectly fit the neck of the brass cartridge neck from .17 to .45. Extremely well made.
With the demise of CRT, I'm certain there must be another maker who picked up on Brad's great idea for a powder funnel design. I know it's the very best one I've ever used for precision handloading.
