I am getting ready to purchase a Dillon 650 to reload on. One of the calibers I'm reloading is 300 BO. I'm trying to decide on case trimmer options and I have been told the Dillon trimmer will not perform well trimming 300 brass after it's been cut from 5.56. Evidently thedillon motor is not designed to cut over a certain measurement and initially 300 brass is likely to surpass this when it is first formed.
My other option I'm considering is the giraud power case trimmer which looks sweet but costs a little more. Looking for input from people who have experience with either trimmer. Thanks in advance. |
Apparently Dillon just announced at SHOT a brand new trimmer - the RT1500 - to address the 300BO issue. Apparently about $30 more than the RT1200, and available within a month or so. Here is a photo from the BE thread:

Sir, FWIW I used a Dillon RT-1200 for quite a few years before Doug Giraud entered the market. I resisted buying a Giraud trimmer for a few years but have been using one now for about three years. I sold the Dillon trimmer on the EE forum. That said I have no experience reloading for the 300 BO so the linear differences escape me. It looks like the new RT-1500 will resolve what ever problems that exist. Although it's been mentioned that the cost of the RT-1500 will only be about $30 more than the 1200 I would bet the special tool head for the 300BO will be extra. I've been using a lot of Dillon products for many years, so I'm confident you won't be unhappy with any Dillon product and if you are they'll resolve the problem, no BS. The main difference, beside price, between the Dillon and Giraud trimmers is the Giraud cutter head can be set to champfer the case neck inside and out as it trims the case length, and the Dillon trimmer doesn't. Your choice between which to buy should be based on your knowledge of that fact. Obviously the champfer capability was important to me but there are some that will disagree. Also you need to look at the Giraud web site to determine if they make a shell holder for 300 BO, or call Doug and ask him directly. I know when I started reloading .30 Carbine I found that Giraud doesn't make a shell holder for that cartridge, maybe true for 300BO as well. HTH, 7zero1. |

I don't have an answer or opinion on your final question, but am curious about the opening part of your post. Is what you are hearing about the RT1200 only have to do with the initial trimming of .223 after it gets the shoulder cut off? Or is there a problem with trimming even after firing converted 223/300 brass?
I have read the posts about the RT1200 not being able to trim full 223 to 300. But other than a problem of case spinning if too much lube is used, I didn't know it had a problem with trimming 223 with the shoulder cut (like with the jig and cut off saw) or fired 300 brass. I have a RT1200, but only have the .223 die. I intend to get a 300 and a 308 die. For my first conversion of 223 to 300, I used the chop off saw with jig for the initial cut, then final trimmed on a RCBS lathe type trimmer with drill power. I assume after I fire these, trimming could be done routinely on the RT1200 with the proper die, just like when I use it to trim fired 223. |

I had a RT1200 with the C4HD die for 300BLK and like an idiot sold it because I wasn't planning on getting a 300BLK. Now that I got a 300BLK I bought the 300 Whisper case holder for my Giraud from Doug. The only problem is that the case is so short it is hell on my fingers and I can only do at most 100 before I need to stop.
If I had it to do all over again I would have kept the Dillon and possibly sold the Giraud. I still may do that now that this new version is coming out. The cut on the Dillon was very nice and didn't really need a chamfer/debur for anything but maybe flat base bullets. |

Gracey's trimmer is cheaper than Giraud's and works very well. It requires Giraud's carbide blade or Bob Jones Sight's carbide blade as an upgrade and it will run like a champ. You can supply your own motor if you just want to buy the trim unit and save money.
It must be oiled prior to every use and it will sling a small amount while you trim. I simply fold a piece of cardboard like a tent over the top of the bronze bushing and it captures any oil that gets spun out. I sold my Dillon with five trim dies to a friend for just $100. Their dies cause too much neck tension which requires a separate operation with an expander plus de-burring and chamfering were not done under power with my Dillon. The Gracey's and Giraud trim, de-burr and chamfer in one pass. |

I form the brass, saw the bulk excess material off of the .223 with a circular or band saw. Then I do the final case trim with the Dillon, CH4D case trim die, and special short too head.
I have thousands successfully done. Yes a deburr may be needed. I have taken off the sharp edges off via a wet tumble in stainless steel media. Still it may be necessary to touch up for chamfer as needed. Bob |
