I am curious which case trimmer you .416 Rigby shooters are using. I have some Norma brass that is getting close to needing a trim. I just bought a batch of Jameson brass so I can use it till I need to trim the Norma. reflex264

In my Ruger #1 I loaded hot enough that I never had too trim . I did get some cracks in the shoulder and small circles where the gas got out that let me know it was time to chuck the brass. It also made me rethink my need for speed and now I like the slower side of things and my brass is loving a much longer life. I have an RCBS trimmer and have never tried it. I really must as I bought the collet and everything.
WOODY Everyone is allowed an opinion, even if its wrong.
Even though Forster do a trimmer especially for large cartridges nowadays. I was able to successfully modify my Forster Classic trimmer to trim 416 Rigby. I had to open out the mouth of the collet housing slightly, & shift the cutter shaft housing onto the second hole to get max span. I used a 45-70 collet & 410 trimmer pilot (this was in the days b4 anyone did 416 stuff.) I had to feed the cases base first into the collet while making sure the trimmer shaft was pulled back so the pilot was within the housing, there was only just enough room. That said, it was no hassle once you were set up & running. Steve

I use a Forster to do mine. Since I already had one with the regular length base, I needed to purchase the longer base. Also had to send the housing to Forster who opened it up to accomodate the Rigby at no charge.

Why not a trim die? I had to buy one for my 500/416. I have not needed one for the Rigby. Peter.
Be without fear in the face of your enemies. Be brave and upright, that God may love thee. Speak the truth always, even if it leads to your death. Safeguard the helpless and do no wrong;
There is one theat uses a drill press but I cannot think of the name at the moment. I was not aware the NE cases would stretch under the low presser unless something was wrong with the headspace. Frank

The Wilson uses a "sleeve" that is cartridge family specific. You insert the brass into the sleeve and it butts up against a "plunger" with the cutter on the other end. The plunger is threaded and you turn it in or out to adjust the trim length.
You have to buy different sleeves for different cartridge families. However, one sleeve works for anything based on a .375 H&H case (for example 375H&H, 300H&H, 7mmRemMag, etc.). The 416 Rigby uses the 338 Lapaulla sleeve. Sounds complicated, but it is not.
I also have a Fosters trimmer that I use for my 470NE. If you want one trimmer that will handle NE cases then you will probably have to go with the big Fosters Trimmer.
We keep a selection of different Wilson case holders, and modify one to fit any wildcat we are working on, or any larger caliber that we do not have a case holder for.
I just bought a Wilson trimmer in the "Ultimate" configuration from Sinclair International. Man was it expensive but it is soooooo precision. It looks very cool on my bench also LOL. They advertise it to handle all calibers up to .416 Rigby. The only down fall is that you need caliber specific collets for each cartridge. Like Saeed said it will the last one you will ever need for your childrens children. Some collets go for more than one caliber such as 30-06,270 and .243,.308.

Also, I use the Sinclair Chamber Length Gauges to determine my rifle chamber length and trim from that measurement, not the trim length given in reloading manuals.
