Trimming large bore cases

[Ray B]

I'm seeking solutions to the problem of shortening/trimming excess neck length from .475 - .5" case mouths. I have a Forster and a Wilson case trimmer but neither are designed for cases larger than about .4" What's available for .5" case mouths?

That’s odd - My Forster classic does my .470ne

I have an older lyman (black) accutrimmer (not blk anodized aluminum like the newer ones, but blk coated steel) that was sold by stating that any cartridge will fit in it (incl. the 50 BMG) and it came with a .50 trimmer. I don't have a .50 (.470 yes-and I've been taunted but resistant several times on nice .500 A-Sqs!) but I'll see if I can find it and IF I have two reamers for those calibers or similar, you can have the big one. Also, I'm sure this will work (or just the reamer) for your application! Finally, have you considered the tried-and-true press mounted trimmer? (Can easily be made by a machine shop out of the appropriate die body, if not!) Just set up to the appropriate length and file and or grind down to the die body. (Reloading equip. is at a fam farm and I'll be there this weekend.) GL! https://lewilson.com/50-cal-stainless-case-trimmer-kit?srsltid=AfmBOopgJW00BfJkk_r1iqliFyjwsqcFXRo5qRU5AJoPLA23Kt3wAiU6u

If I am remembering correctly, I purchased a replacement cutting head for my RCBS trimmer that was large enough to handle .510" cartridges (.495 A-Square). Just swap the cutting head. Maybe your cutter has a similar replacement available?

I found the answer. I have a Forster Original Case Trimmer. It has a head suitable for cartridges up to .458". What I need is a Forster Classic Case Trimmer that works on cases to at least .5". So looks like in addition to my Wilson and Original Forster I will be getting a Classic.

Get the Wilson 50 bmg case trimmer. It trims my 577 3” cases (just barely), and should easily work on 50 and 475 cases.

The problem with the Wilson is that a case holder is needed for each case- which I have for several cases. but they don't make them for 470 or 475 cases. So I'm better off with the Forster which has a collet to hold the base and a pilot to hold the neck and a cutter of nearly .6" diameter.

I own one of these. What holder are you using? Would love to not use a Trim die for my 577 cases.

I use the smaller wilson as well with at least 30 case holders. 40 cal and above I use the Fortner.

Use the Henderson or Giruard for the higher volume stuff.

They will make any holder you want. I’ve had several done. They just need 2 or 3 sized cases and a few weeks. I believe the cutter for the 50 bmg measures north of .6”, but don’t quote me.

See my previous post, they will make custom holders, but you typically have to send in a question first, then they will instruct you to send a few cases to them along with a service order no. related to your question.

I have just gone through this same situation this week.
The best solution in my opinion is to just order the LE Wilson 50 BmG cutter. I just got the basic one which can be held in a vice. Only $175 aud at the Q Store in Brisbane Australia. They have 6 more in stock now.
Then I ordered a custom case holder for my 500 Jeffery. You don’t need to send in any cases, just fill out the below form and they will make it.
Simple , not to expensive, and you will get precise cutting.

That’s a very good price for anyone who wants one.
But of course you will have postage on top of that.

Nice, didn’t know they had a form as well.
