Tonight I processed 169 pieces of .22-250 brass in 78 minutes. That is complete processing... individually lube (Hornady Unique), collet neck size, body size, primer pocket clean, trim, chamfer, deburr.
I measured the first case and an occasional one after. The first measured 1.9025. Every one I measured after read 1.9025 or 903.

Brian Pfleuger, did you measure the length of the case from the shoulder to the head of the case? F. Guffey |

I didn't measure every single one. They were all sized before trimming, using Lee collet neck dies and Redding body dies. Shoulder measurements are typically within 0.0005, 0.001 at worst. IIRC, the shoulder length (setting) was 1.562.

Frankford Arsenal Trimmer
I have just started reloading rifle cartridges and as a result needed a trimmer. I decided to buy the Frankford Platinum unit. Here are my observations.
I think the unit is well made, as stated already on this thread it is heavy and operates at a relatively low rpm. I do not think it is the most consistent trimmer but for my needs it will suffice. I run mine seated in a large Tupperware container and all the brass shavings are contained. The one issue I have is the chamfer and deburring heads. I think I have dulled mine, maybe by pushing too hard on the cases? Where can I find replacements? I am only trimming 223 at this time. |

If you contact Frankford Arsenal they could probably get what you need.
I'm still very much liking my unit, it makes trimming a breeze. |

Case length uniformity is the least important dimension for best accuracy and muzzle velocity spread. A .015" spread is meaningless.

I just phoned Frankford and they are sending me two new trimming attachments.
They said that there had been a batch that were not properly heat treated. |

Glad they are sending you two new attachments. I also have the trimmer and love it. For future reference, you may be interested to know that the Lyman case prep tool heads like these: http://www.lymanproducts.com/lyman/c...fer-reamer.php can be used. The metal part unscrews from the handle and is threaded the same as the holes on the Frankford trimmer. I use the Lyman VLD inside chamfer head and the Lyman outside chamfer head on mine.

On order from midway
Lots of LC 5.56 and SSA 6.8 to trim!!!! I plan on using a Hornady cutting head and hornady pilot bushings per a video I found on the tube.

I haven't seen the Frankfort one, but I've been tempted by the RCBS version often - I just always find something else I need more for the $125.

I'm happy with my Giraud Triway cutter. $90 and it trims, chamfers and deburrs in a single shot.
The drawback is that it is caliber specific, so you'll have to have one for each caliber. But I don't load volume for anything in rifle but .223/5.56 for the AR. My hunting rifles can be done on the Forstner because I just don't shoot that much with them to develop huge quantities of brass to prep (thankfully). http://www.giraudtool.com/Tri%20Way%20Trimmer.htm |

Frankford Arsenal Case Prep Machine
I've been reloading since the 1950s. I have used many case prep machines and my latest which I bought in 94 is the RCBS motorized case prep machine which only trims the length. It's the most accurate and I use it to trim cases for my Rem 40X.
I just bought the Frankford Arsenal machine last week off of Ebay for $156. I have reloaded about 500 rounds of 5.56 trimmed for the SS-109 bullet. The trim length is 1.750" for most cannelured bullets. The cannelure is the most important consideration for semi and full-auto rifles. The new machine references off of the neck so the is some deviation from 1.750" because of differences in bore profile. Some of the casings are once-fired brass bought in bulk and others are from the local range, so this would answer the question of differing bore profiles. The differences range from 1.735" to 1.7535". This range is acceptable for the 5.56 under all circumstances except for precise target competition. I have found that the deburring tips can be changed to other brands. The biggest problem I've found with this machine is that the trim length cutter wears a bit faster otherwise it seems to be a good buy. |

I have trimmers, I also have forming dies. When forming cases I trim as much as 27" of brass from 100 cases. I get more millage from a hack saw than I do from the cutter of a case trimmer. Then there is the file, I have files, I use files when trimming. The file when used with a form/trim die is one of the most accurate methods for trimming.
I have the RCBS case prep center, no, it does not trim but when loading it is one of the first tools I set-up. F. Guffey |

I picked up the FA case prep center a couple weeks ago. I have only prepped 75 or so 5.56 cases with it, but dang is it far better than the Lee setup in a drill for my uses.
I have been using the Lee method since I started reloading back in 08. And that was a fine method for the many different calibers I was shooting. But a couple years ago when I got into shooting AR's and the sheer volume I am now shooting them, case prep became very uncomfortable. 200-400 pieces of brass at a time. My hands would often cramp up and I would have to prep cases over a couple weekends at a time. This FA unit almost makes me enjoy prepping brass! I so far am happy with it, time will tell on the lifespan of the product, but I for sure will be running it through its paces to find out. Also I did see that vid already mentioned about using the Hornady bit and using the collet, that may be a good idea.

I also have air craft countersinks, not a problem when matching the neck to a guide, when using a forming die the small flair snaps off when the ram is lowered. It is not even necessary to cut the metal, just turn the counter sink and flare the protruding neck, then, lower the ram.
If trimming a case or case prep run me to the curb I would quit reloading. F. Guffey |
