Dillion rapid trim die issues

[Huskydriver]

So I understand these are small based dies but good night.... I'm running a sizing die in station #1 and the rapid trim in #3. I have 6.5,308,300 wm, and 223.

With the 300 wm die no matter how much lube I use, if I try to size beyond 80% of the way down, I'm ripping the rim off the case on the down stroke.

I have tried 3 diff brands of brass fired from two different chambers.... All the same result.

I got my 6.5 trim die to work because I can set the trim die to only size 80% and there is enough brass sticking out to trim it to spec but not with the 300 wm die.

I'm calling Dillon tomorrow but I have a feeling they will say yes that's the way it is send it back for a refund or tough luck have someone hone it out. Anyone else have this issue?

After a cycle or two, the body of the belted magnums depend on how the chambers are reamed. Many get too large above the belt and are not sized there by conventional dies. Take a look at this tool and see if you think it might help. I don't run belted mags on progressives. When I do run bottleneck cases on the Dillon, I do it in stages.

Edit to add, their web page is a little plain. Look about half way down and you will see it.

All this brass has only been fired once. I agree and have seen this happen with 5+ firings on it. Never seen this happen on the first firing... Funny thing is, the fired brass still chambers so it still has some growing too do so there shouldn't be a bulge yet above the belt.

If you lube a case a go strait to the trim die (skip die in sta 1), do you still have the problem?

Not loading 300WM but I run two sizing dies when processing on the Dillon.

A standard die in station one that bumps 80%?

And than the RT die.

No undue pressure up to 30-06.

Now I am having an issue with one rifle and the very bottom of the case not being sized enough for its tight chamber.

I dont run the RT die any tighter than necessary to hold the case while cutting and get my .001-.003 setback.

In doing so Im wondering if thats what is leaving the last 1/8" of my brass fat.

I may run the RT die just tight enough to hold while trimming than run a Redding FL die after the RT. Thinking this will screw with my trim length some but if I can do it and still end up within SAAMI spec it may be an answer.

I think Dillon runs the SB rapid trim because they want to ensure the case is held tight enough to keep from spinning while trimming. I dont think they need to be held that tight.

Sucks but perhaps adding a die to the process may help with the 300WM.

The convenience of the RT is such that you really want to make this work.

Love my RT.

Yes it's even worse.

Love my RT.

I love my rt too but this die is rediculously tight.

It's Karma getting to you. You're doing too much shooting, you need to spend more time reloading! I'll help you and and let you do some reloading for me as well.

300wm is gunna be hard to trim in the dillion. You probably don't want to size the bass that much anyway. Keep it close to the chamber size.
Trim it on a normal trimmer. I love the rcbs 3 way trimmer. I use it for all my bench stuff.
I bet you can trim new brass in that die before its blown out. So an option is buy new brass and work out the trim length that ends up what you want after the first fire and reload.

If you want to use that die you may have to have the the trim die cut closer to your chamber size. I don't remember who makes it but someone make a trim die with an oversized body for 300wm. It uses the neck and shoulder to hold steady while trimming. They claim you can shoulder bump in that die as you trim. But they also say you have to expand the neck with oversized expanders to later use a bushing die.

I love my dillion trim setup. If you do 300blk it's the best way to make brass.

Did you talk to Dillon? Curious of the outcome.

Dillon, as always were willing to swap it free of charge.

However, I am not holding my breath that the new one won't be just as small. I could careless if I can't use the whole die as I FL since and decap in station #1 already, but because the cut out for the brass neck to protrude is so high, you would have to almost FL size in this die in order to get the brass to stick out far enough for the trimmer to cut it.

Wanted to follow up.

Dillon fixed my trim die.

They sent it back with no note explaining what they found but they must have honed or polished it because all of my brass sizes like normal now.

Now to send my 6.5 and 308 die back for the same issues.
