On the subject of trimming.

TheOtherZilla

Pull my finger
I read with interest all the threads about the New RCBS/Hendersen trimmer. As well as the Geraud etc. Thanx to members here I researched solutions as I didn't want to spend $7-$800 to ease my wrist pain. Currently my main trimming is done on Lil Crow trimmers. But my wrists are rebelling if I do more than a few. I had this RCBS power trim unit sitting around and not being used. I found RCBS makes a cutter/chamfer fitting and it will screw right onto my Power Trimmer. Bought one in 20 Cal and one in 22 cal. Set it up and tried it today. Viola! trims to the exact length and chamfers.
And yes that is an Inline Fab mount plate.

Cool setup. Bulky, but if it works - why not.
I have been trimming on a Frankfot Arsenal but its was inconsistent because it relies on the shoulder distance to the cutter. Then when I got serous with precision reloading I got a manual Forster trimmer with the 3in1 carbide cutter head. It cuts,chamfers and deburs in and out in one process. Its manual , but I don't trim unless I get to 6-7 firings.

RCBS makes those 3way cutters in 30 cal and 22 cal.

(Have both and love them)

Completely adjustable for the inside and outside chamfers...

I did get (and highly recommend) their carbide main cutter and use that on my frequently used cutter head. Smoother cutting and will most likely last longer than me...

At some point in the future I plan to make my own outside cutter from a carbide drill bit just because I can but doubt i would ‘need’ it... no way I could make the pilot / inside cutter in carbide even if I wanted to. Would be very costly to have one made for there as well.

Yes bulky and slow. I already had it and the Inline Fab mount makes it versatile. When I'm done off it goes to a storage shelf. Beats paying for a high dollar trimmer.
 
Yeah man trim and chamfer kills my hands even with a power trimmer and prep station. I have a 3 way for 22 cal and its soooo much better for that high volume 223.
 
The RCBS 3 way is the cats meow
especially for its price
I made an adapter so it will fit on my Forster trimmer/turned so can use a drill
so its powered and can do lots quickly and easy

I thought the pilot had a fixed inside chamfer cutter, non-adjustable. I remember them being extremely janky to adjust, inside chamfer was not a real vld chamfer and they didn’t really turn true. I thought I was really gonna cut a fat hog in the ass, but quickly got rid of them.

Life is too short to not have a Henderson

If my Henderson cleaned/uniformed primer pockets in the same process I’d pay double. Brass prep is a drag, overrated.
 
The RCBS works just fine if you adjust it correctly. Both inside and outside can be adjusted. And yes the inside is on the pilot. But can be adjusted.
 
1/2 drive drill motor running a RCBS trim pro with 3-way cutter. Makes quick work of a batch of brass.
 
I have the RCBS Trim-Pro II and added the three-way Head . As mentioned ; once you get it "SET" correctly , it will repeat within .001 all day long . Now ; I just have to find a power unit like the one pictured . Doing 4-500 cases by hand at a time is a drag and my wrist is revolting .
 
I trim and chamfer in two steps despite both being motorized....Dillion 1500 in a 650 and a Giraud.

When I'm staring at 1000s of PD cases to reload it's kinda compelling to be as efficient as possible....hence the 1500, 650 and case feeder when ever possible.

I reload on a 1050 but haven't set it up for the 1500. The 1050 is auto equipped so I really need to get to that.

I reload 15-20K for my PD host and I can never be sure what their OAL is so the 223s go through the 1500 in their resizing pass. I've used up 56# of powder so far for next season and still have about 4-5K to load.

I've found that it's very consistent and efficient to first trim on the 1500 before chamfering with the Giraud.

It'd really be nice to have a tri-way cutter for the 1500 for extra efficiency. I've toyed with the idea of using a Henderson tri-way cutter mounted in a router but it would take a 11/4" trim die to accommodate the cutter...doable but yet another project.

I have one of these I should probably sell, but they are so dang handy and easy to adjust. I have mine mounted to a 2x6. It has trimmed thousands of rounds of .223 with the 3-way cutter.

How do you have the die stations on your Dillon set up for loading? Are you manually feeding bullets? Powder check? You ever wish you had a couple more threaded stations?

For sizing on 650:

#1 sizer die with decapper
#2 blank
#3 blank
#4 Dillon 1500 and trim die if needed
#5 blank

For loading on 650:
#1 blank
#2 powder drop/priming
#3 custom M type expander die
#4 bullet drop
#5 bullet seater.

For sizing on 1050 with auto drive:
#1 blank
#2 Mighty Armory decapper
#3 swage hold down die
#4 blank
#5 blank
#6 blank
#7 sizer sans decapping apps/opposite the swage hold down die to take slack out
#8 blank

For loading on 1050 manual pull:
#1 blank
#2 blank or a collet die if needed
#3 blank
#4 blank/ primer
#5 powder drop
#6 custom M type expander die
#7 bullet drop
#8 bullet seater

I have learned that the case mouths contaminate the bullet drop with sizing lube and powder granules if I try to size and load in one pass, eventually resulting in bullet drop failure.....hence the separate sizing/decapping pass and a trip through media to clean off lube.

I do not use a powder check, but I can see a need for one. I try to use ball or very short stick powder only to avoid bridging.

I've had to weigh loaded rounds a couple times because a bullet plugged the powder measure.... probably from pulling bullets and failing to separate all the bullets from the powder and dumping powder back in measure. Ironically the slide still fully functioned but with zero powder drop. NO MAS.

Yes another station would be good for a powder check. I suppose I could move expander to before priming when loading and use #6 for powder check or just rely on the Dillion expander in the hold.down die.

I did customize the Dillion expander to do both 223s and 20 VTs. The 20 VT expander just rides below the 223 expander on the same shaft. However I just like the versatility of my custom M type better.

Just got my mark 7 apex 10 set up with bullet feed, every station is used. Lot going on.
