There are very few things in my humble opinion that is as rewarding as trying to achieve the most accurate ammo as possible assembled by your very own hands from your reloading bench. To be able to strike that steel plate 200, 300, 600 yards away or shooting those sub MOA groups at varying distances is a very rewarding accomplishment. To achieve that sort of satisfaction with reloaded rifle ammunition and bottleneck cartridges uniform trimming of your brass becomes essential. I find trimming the most time-consuming step in the process of reloading and up until now absolutely hated it. I think if you ask any reloader to name the most tedious part of rifle case prep, more often than not, the overwhelming answer will be trimming. To avoid trimming rifle brass I would often purchase additional once fired fully prepared brass to avoid the tedious process of trimming. I have used many manual trimmers and they all work as advertised but the process can be quite strenuous. There is also several cost effective power trimming options I have used that are available on the market that can be mounted in your cordless power drill or drill press. This class of trimmers work very well and are less strenuous yet it still was not as fulfilling as pulling the lever on the press and watching completed rounds fall into the bin. With so many empty 223 and 308 once fired and range pickup cases it just didn't make since to continue with my dislike of trimming. I then began scouring the Internet for a high volume powered trimmer and I found CTS Engineering. This has now become my favorite reloading tool --- sick huh but thats how easy it makes trimming.
