Precision-machined top punch for RCBS Lube-A-Matic and Lyman 450/4500 sizers. Eliminates nose deformation with exact bullet nose fit. Quality construction at an affordable price.
The RCBS Lube-A-Matic Top Punch .558 is engineered to solve one of reloading's persistent challenges: bullet nose deformation during the sizing and lubricating process.
When you're sizing and lubricating bullets, the top punch is the critical contact point. A poorly fitted punch can deform soft bullet noses, compromising both the appearance of your ammunition and potentially its performance. This punch's exact fit prevents that problem entirely.
Whether you're a dedicated handloader or new to the reloading bench, this accessory represents the kind of thoughtful engineering that separates quality reloading equipment from the rest.
