RCBS 3-Way trimmer problems

[squeeeeze]

Bought 3 3-Way trimmers and 2 more trim pro 2's. Used the .28 cal one last night on my 28 Nosler, Nosler brand Brass (cheap brass lol). It's scoring the inside of my necks pretty bad and creating a lot of resistance when seating bullets. Been using a trim pro 2 with std trimmer and my own VLD inside and outside chamfer for a few years and have worked fine but hoped to speed up the process not slow it down.

Did 25 pieces last night, tried using my VLD inside chamfer after last night to clean them up but they're pretty deep and won't touch it. Any suggestions for stopping the scoring? What about to smooth up the inside of the necks that are scored pretty good?

Worst case I'd be ok using a regular pilot and just using my own VLD inside chamfer afterwords if the std pilot will go in it or use the std cutter on the 3-way but would love to have all steps done at once.

I meant to post this in the reloading forum. I apologize, Mods please move this thread.

Anybody else experience this?
Solutions?

I was hoping I could just use the regular trimmer pilot while trimming and deburring the outside and just inside chamfer separately, but pilots won't fit. Creating a lot more tension while seating and exasurbated a problem I was having with my seating die.

Not sure if I will have the same poi yet or will increase pressure due to a potential stronger bullet hold due to the rough ridges it's creating.

i dont use a 3 way cutter , i may be off here but ill throw some ideas out since you havent had any replies yet

if you are you sizing before trimming , your neck is undersized and too small for the pilot , you probably have some brass smearing on the pilot too , maybe you can sand down and polish the pilot to meet the diameter to fit your existing process, or do the trimming before sizing -- you really dont need a tight fit on that pilot , just tight enough to keep it from wobbling

the other thing that would do that galling would be heat buildup from friction from going too fast , are you powering it with a drill ??

then how to fix it , you could shoot it and make sure its a problem you can see and eventually it will work itself out
or, you could probably run it through your full sizer die with expander button in 6 -8 time each then anneal em.

or best way, inside neck reamer would probably do the best job as long as you had a expander that was Barely under the cut diameter , which should probably be annealed after as well

Thank you for the response and great ideas. I've pictured my trimmer with the 3-way trimmer installed and the regular trimmer pilot I am holding. It looks like a bad design for the 3-way trimmer pilot as it has a nice sharp ridge for the peak compared to the regular pilot that is flat and smooth at the largest meeting area. The regular pilot measures .2795 and the 3-way pilot measures .2805. The I.D. Of my sized neck is .2810 my fired case I.D. Measures .2840-.2845.

I size before I trim so I can get consistent trim lengths. If the pilot touches the inside neck at all it will groove. I may take a stone and spin the trimmer and try to smooth the pilot out from being so sharp. I haven't used my 6mm or 6.5 mm 3-way trimmers yet due to this issue. I do have the new style (trim pro 2) and it has the universal shell holder which is tough to get 100% concentric, but I'm just used to messing with the case and fine tuning till I get there or close and I'm sure that doesn't help with this design.

I just started to use a cordless screwdriver for this trimmer but do it at the slowest speed and equivalent to my hand turning so I'd have the same issue either way.

I did call RCBS about this problem and they said they would send me another one out and they'd double check it was the same as their prints, if it didn't work to call them back and we'll go from there. The 6mm and 6.5mm look like the same design so I'm sure nothing will change but at least give me one to try and correct.

I had regular pilots gall my brass once so I polished them up with some JB paste. I'm thinking either the pilot has some burrs on the flutes or the brass is off center so putting "hard" pressure on the pilot.

Is the galling on one side of the brass or all the way around?

As far as polishing the scratched up brass on the inside I wonder if running them in a tumbler with some cob and polish would work.

It's pretty even all the way around.

I ran my gnurled neck sizing ball through the neck a few times and sized the brass, it seemed to help smooth a bit. they're now in the tumbler for the night and think they'll be ok.

It's hard to tell in the picture but there is a distinct sharp peak on the pilots. Good advice. When I get the time I'll try and hone that ridge down some and maybe even polish the pilot and see what I come up with. Thank you again for the advice.

Would emery cloth be too much for smoothing out/polishing the inside of his case necks?

I haven't used emery cloth much but from I've seen I think I'd use something less abrasive. I would think emery cloth would take off too much material, what say you? I think I'd run it in a tumbler or try some never dull wrapped on a looser fitting bore brush.

 

[xsn10s]

I think the last time I used emery cloth was for polishing some S&W Model 10 parts for a PPC revolver. So that was on tool steel not brass. Geez that was two decades ago this year lol.

Ha! Yeah, I'm not sure....I've used it to polish pilots down before and I've seen videos where it has been used to take off a VERY slight amount of inside neck material to allow bullets to slide freely in modified cases. I guess it would depend on how badly the op's necks have been gouged/galled.....

 

[xsn10s]

Yeah pilots would be good to polish lightly with it. I'd just hate to tell a guy go for it at what $2.25 a pop? If I remember correctly I didn't do anything to aggressive with the cases. But I've recently learned my memory ain't that good anymore, and I hate eating crow lol.
