Thick case necks are one of those problems you don't notice until your groups start opening up or your pressures creep higher than they should. The Forster NR1432 Inside Neck Reamer takes care of that by shaving the excess brass off the inside walls of your .44 caliber case necks. It's ground to a .4325" diameter, which runs about .003" over the .429" bullet it's meant for, giving you clean clearance without taking off more than you need.
This reamer isn't a standalone tool. It mounts in the cutter of a Forster Case Trimmer, dropping in place of the pilot, so if you already run an Original, Classic, or Power trimmer you're ready to go. You insert the shank into the cutter shaft, lock down the set screw, and turn the assembly until the reamer passes all the way through the neck. One of the nice things about doing it this way is that trimming and reaming happen on the same bench setup, so you're not juggling a dozen different tools.
The body is ground from high grade, wear-resistant tool steel, so it holds an edge through a lot of brass. The staggered tooth design is the real story here, since it cuts smoothly and keeps the chatter down that you'd otherwise fight with a cheaper reamer. Clean cuts mean less cleanup and more uniform neck walls, which is exactly what you want when you're chasing consistency in your .44 loads.
Timing matters with this one. The reamer is built for use after a case has been fired with a full load and before you run it through your neck or full-length sizing die. A simple way to check if you even need it is to slide a bullet into a fired, unsized neck. If you feel drag or interference, there's brass to take off. Chamfer and deburr the mouth once you're done and you've got a case ready for the next step.
It's sized for .44 caliber brass using .429" diameter bullets and reams the inside of the neck to .4325". It mounts in the cutter of a Forster Case Trimmer in place of the pilot, so you'll need an Original, Classic, or Power trimmer to run it. The reamer itself doesn't come with the trimmer.
Standard reamers like this one are meant to be used after a case has been fired with a full load and before you run it through your neck or full-length sizing die. The general rule is ream after firing, turn after sizing. Reaming at this stage removes the brass that flows forward on the neck during firing.
The quickest check is to slide a bullet into a fired, unsized case neck. If you feel drag or interference, there's too much brass on the inside walls and the neck can stand to be reamed. A tubing micrometer gives you exact wall thickness numbers if you want to be precise about it.
Forster grinds standard neck reamers roughly .0025" to .003" over the maximum bullet diameter, which is why this one measures .4325" for a .429" bullet. That extra clearance matches common chamber neck tolerances and keeps your loaded rounds from being too tight. It helps hold pressures in check and cut down on flyers.
