L.E. Wilson case trimmer - Chamfer tool attachement

[Raydee]

I see that they sell a chamfer tool attachment for the Wilson trimmer. They sell it in 45* and 30*, I am thinking 30* would be the
better option when loading boat tail bullets?

45* for flat base?

 

[BoydAllen]

Actually, I have found that BT bullets are not at all critical as far as chamfer goes. FB on the other hand do better with a more gradual taper, and a wide chamfer. Don't just perch the bullet on the case mouth. Make sure its bases stays within the chamfer. This is especially true with hand made bullets that have significant pressure rings. Taking a little time to get this small detail right pays dividends in concentricity.

That looks like it would be very time consuming to go that route.

I don't load a large amount at a time, so I don't mind.

Honestly, don't bother.

Stick one of these in a drill or screwdriver, and do this process by hand, and quickly/effortlessly.

Only warning: that SOB is "REAL" sharp, with a ton of carbide flutes, so you can over-cut a piece of brass quickly. Just a dab'll do ya.

That cutter will do up to .30 cal with ease. I just got done with a batch of .30-06.

I use one. I have 2 Wilson case trimmers set up side by each, one with the trimmer cutter and the other with the chamfer cutter. I trim the case then got directly to the chamfer setup while the case is still in the case holder. Works for me.

Ok but what degree chamfer do you use?

30° usually but I have both

What do you use to release the case from the case holder? I usually tap the mouth on a piece of heavy brass bar, but I worry about deformation.

 

[Raydee]

From my limited experience they don’t need to be jammed in very tight. A light tap to put it in the holder and a light tap pops it right back out.

I see far more value in a 3way cutter. No idea what can be easily adapted to a Wilson trimmer though.

Years ago I bought a Sinclair base for the Wilson’s and it came with a Derlon or uhmw block and has served me well for many years

I am loathe to tap my case mouth on anything so I keep a shell holder and small screwdriver at hand. Slip on shell holder and pry case out with the screwdriver between the Wilson case holder and the shell holder. It’s annoying, but easy enough and doesn’t require any contact with the case mouth. Often the shell holder alone gives enough purchase to just pull the case out by hand without using the screwdriver.

Wood block

I was using wood (some scrap I had lying around) and found the chips and splinters that developed would get annoying. I'm thinking maybe a piece of heavy aluminum sheet would be better than brass. I've also got UHMW and nylon sheet, but I'd have to cut that out from a large square piece, which I'm kind of reticent to do for a small block.

Use the end grain on a wood block. I think some may be tapping their cases in the holder way too much, it only needs a very light catch.

I use a single tap (an inch or two of throw - certainly not jamming the case into the holder) to seat the case in. Sometimes take 2 or 3 taps to get it out though. I think I'll start looking for a small block of HDPE - should be hard enough to not deform (as LDPE or nylon - at least the stuff I've got - does.) Not that I trim cases all that often; this is a back-burner problem at best.
