Best case trimmer for straight wall cases?

Marplot · Dec 4, 2024

I am reforming brass for obsolete calibers. Right now I an trying to reform 30-30 brass to 8.15x56R. My reforming dies are turning these cases into appropriate straight wall cases, but these are coming out too long for my rifle. Most case trimmers work on "shoulder cases" since my brass is straight wall and they can't work. I use a Forstner press and does not use any additional shell holder, so a trimmer would be nice to have a universal shell holder.

Do you like a particular trimmer? My brass needs to have an OAL of 1.831.

I probably need about 20 rounds, so I may use my metal lathe but not sure how a rimmed case will chuck. I think wrapping a piece of leather might hold the case well enough.

Sorry, rambling

Best ideas?

How about a Wilson case trimmer with pistol case holders? Very accurate and adjustable on case length.

Wilson looks good, I especially I can clamp it in a vise. I am not sure it will work with a straight case. However they say it will work with 45-70 case. Also want to be sure it will work with an 8mm and 8.15mm. Email to Wilson.

I did a quick search and found they have a holder for .40 S&W which is a short straight walled case so I think you would be good to go. Do a search on the case holders you need. If you can't find one, they can probably make it for you.

You have a metal lathe. I would guess you could make your own case holder if using the Wilson trimmer.

I would use the Lee.

The Wilson will be a pain if no taper. Most straight wall rifle are tapered, but pistol are straight causing the need for the Q type holders which are a PITA.

Lee has and adjustable length limiting pin and chucks in a drill well.

I use a Forster case trimmer. Has a stepped collet shell holder.

You could see if Hornady makes a pilot in the correct size, if they do that's an easy trimmer to use with straight cases. Locking head through a shell holder, and a pilot on the cutting head.

Do you have strips of lead, like some guys put inside the chuck or spider when dialing in a barrel? Use a cold chisel, pop a line for the rim in two of them, and chuck the cases in by the web. Or maybe that's a redneck solution when you don't have the correct tooling

Leather is probably more than enough though, not like you're cutting with much pressure.
