Just wanted to pose a review of the new RCM laser powder check. We all know the problem with probe-based powder checks are the mess they make on our presses (Unless you are in a humidified controlled room). The RCM laser powder check mitigates this issue, but better yet it provides far superior adjustability and accuracy.

Just wanted to pose a review of the new RCM laser powder check. We all know the problem with probe-based powder checks are the mess they make on our presses (Unless you are in a humidified controlled room). The RCM laser powder check mitigates this issue, but better yet it provides far superior adjustability and accuracy.
This laser is pin point accurate, but unfortunately the manner in which powder measure fills a case is not. A friend and I were loading 9mm with three different loads using HP-38, CFE Pistol and Silhouette. Here is what we found:
We used brass sorted by head stamp (in this case we ran federal once fired brass that was wet tumbled with 1/8” diagonal cut stainless steel media, de-capped and roll sized on a rollsizer.com commercial unit). The powder charge was set at 4.3 Gr of HP-38 and verified on a FX-120i scale. We followed the setup procedures by RCM with the proper charge and the upper limit alarm to +.020” and the lower limit alarm -.015” (We don’t mind the load a smidge hot, but to meet power factor we definitely cannot have under charges). The press was run at 1000 rounds per/hr. with the top and bottom dwell set at 8. During the run we did not get any high alarms, but we did have a few under charges, those charges were .05gr or less that activated the incorrect charge weight stoppage. We did get a few false alarms during the process, we attributed this to how the powder splashes as it falls into the casing from the powder measure.
Even though we do not chase the lower spectrum of power factor, these settings would allow for very tight tolerances for those who do. For Major match ammo we as individuals would rather dump and recharge versus getting a DQ at Chrono for not meeting power factor
The next run we did was with mixed range brass (brass was processed the same as the once fired brass). To be cautious we ran primed cases without powder pass the laser. During this process we noted which cases were on the extreme portions of the spectrum in regards to height. As this is my competition load for CCP I knew in advance that 3.8 Grains made power factor and provided significant energy to eject the casings. We placed 3.8 Gr. of HP-38 in a LAX casing (as the base of the case was the furthest read from the laser) and set this as the lower alarm level (.344) We than took a Seller & Bellot case (as the base of the case was the nearest read from the laser), placed 4.0 Gr of HP-38 and took a reading and added .005” and set that as the upper limit (.286). We ran 450 rounds and had a fistful of low charges, each of these charges was activated due to undercharge. We weighed each charge and they were all 4.0-4.04 gr., the common factor in these alarms was they were all LAX casings. During the entire run of 450 rounds we did not have a single over charge stoppage. The Lower to Upper alarm range was significant at .058, unfortunately mixed range brass is just that. The majority of the powder filled cases measured .308 to .324, there were very few outside that range and once again we attribute the fluctuation was due to the brass.
This load is a CCP load and nowhere near the upper end of the load data as the power factor needed is only 105. Individuals loading near the top of the load spectrum or +P loads we strongly encourage you to use the same head stamp of brass to mitigate any over pressurization.
In conclusion, this is by far the most accurate and adjustable powder check I have encountered. Most powder checks will alarm anywhere from squib or double charge for one vendor, .1 +/- on another (lots of false alarms due to mixed brass or .2 +/- on another (again lots of false alarms with mixed brass). During my reloading tenure I have used these 3 different powder checks, not a one of them even remotely compares to the accuracy of the RCM laser powder check!
