Let’s Dive into RCBS UPM-3 Competition Powder Measure
The RCBS UPM-3 Competition Powder Measure promises precision and repeatability for reloaders seeking to fine-tune their ammunition. RCBS, a name synonymous with quality reloading equipment, aims to deliver exceptional accuracy with this measure, catering to both pistol and rifle cartridges. Its single cylinder, micrometer adjustment, and ambidextrous handle suggest a versatile tool for both seasoned competitors and meticulous hobbyists.
I was tired of inconsistent powder charges throwing off my groupings at long range. I wanted a measure that could consistently deliver precise amounts of powder, especially for my precision rifle loads. My old powder measure was fine for plinking ammo, but I needed something capable of extreme accuracy.
The RCBS UPM-3 Competition Powder Measure arrived in a no-frills package, but the heft of the unit immediately conveyed a sense of quality. The green finish is classic RCBS, and the components felt solid and well-machined. I appreciated the smooth action of the cylinder and the tactile feedback of the micrometer adjustment.
I had been considering the Redding 3BR and the Hornady Lock-N-Load Powder Measure. Ultimately, I chose the RCBS UPM-3 Competition Powder Measure because of RCBS’s reputation for durability and the simplicity of its design. I wanted a measure that would last for years and was easy to understand and operate. The simpler design seemed less prone to mechanical failure.
My first impression was one of cautious optimism. I was excited to see if it lived up to the hype, but also a bit apprehensive, as powder measures can be finicky. I knew I would need to pair it with a good scale, but the initial feel gave me hope for improved consistency.
Real-World Testing: Putting RCBS UPM-3 Competition Powder Measure to the Test
First Use Experience
I tested the RCBS UPM-3 Competition Powder Measure at my home reloading bench, preparing rounds for a precision rifle competition. The weather was mild, but the humidity was relatively high, something that can sometimes affect powder flow. I was loading .308 Winchester with Varget powder.
The RCBS UPM-3 Competition Powder Measure proved easy to mount and adjust. Finding the correct charge weight using the micrometer was straightforward, although it took a few adjustments to zero in on the desired amount. I didn’t experience any major issues, but I noticed some minor variations in charge weights.
The initial throws seemed consistent, but after about 20 throws, I noticed some bridging with the Varget powder. I solved this with the included powder baffle. After installing this component, the throws became significantly more consistent.
Extended Use & Reliability
After several months of use, the RCBS UPM-3 Competition Powder Measure has proven to be a reliable and accurate tool. I have used it to load thousands of rounds in various calibers, including .223 Remington, 6.5 Creedmoor, and .45 ACP. It has consistently delivered accurate and repeatable results.
There are no noticeable signs of wear and tear, and the finish still looks new. I’ve kept it clean by occasionally wiping it down with a dry cloth and using compressed air to remove any powder residue. The action remains smooth, and the micrometer adjustment still provides precise control.
Compared to my old powder measure, the RCBS UPM-3 Competition Powder Measure is a significant upgrade. The increased accuracy has translated to tighter groupings on the range. It has definitely exceeded my expectations and improved my reloading process.
