Need to buy a new trimmer. I've been using Lee's trimmer for 20+ yrs and have always been satisfied with the results. Unfortunately, Lee doesn't make a case length gage for 204 Ruger. So now I'm looking at Wilsons Trimmer. My question is how is the case that's in the holder prevented from spinning when contact with the cutter is made?
Thanks In Advance!

By friction. Have the Wilson, and couldn't be happier.

Just to add to Lee's answer. When you insert your case into the holder, you tap the base of the case, and the friction keeps the case in position. When you set your case holder (and case) into the trimmer, just swing the arm over the holder, and again, friction holds everything in place. You can then trim your case. After trimming, remove the holder (and case) and lightly tap the case mouth on the derlin (sp) block to loosen...then remove the case. Sounds more complicated than it is, but the Wilson trimmer works great.

Sinclair makes an accessory they call the "Sharkfin" which is a clamp attachment for the Wilson trimmer and their stand. Works like a champ!

When looking at the Wilson case trimmer, what accessories do I need? I buy the trimmer, then what about the holder and trimmer for the 204? This looks like it can get expensive pretty quickly.

Be forewarned the case holders are different for "new" unfired and fired cases. Most of the new cases I had did not work in the "fired" holder, could not push them in far enough to stick. On the other hand most of the "fired" cases worked in the unfired holder. Almost could have gotten by with only the new holder.
Get the Sinclair/Wilson with all the bells and whistles.

I'd suggest you follow MT204's advice and go for the

Sinclair/Wilson with all the bells and whistles.

That way you'll cry only once instead of adding accessories one at a time.

Okay, the L.E. Wilson trimmer is here, set up for .204 and I trimmed the first case. Very nice, simple to figure out and adjust. On the same case I tried out the inside neck reamer. My Hornady 32gr. VMax bullet falls in! Where'd I go wrong? Cases are neck sized only, once fired Winchester.

You only have to ream them if they are too thick. Why did you ream your cases? Run them through the resizing die again, if they will hold a bullet you can use them, if they won't hold the bullet throw them away and start over with a new batch.

Only did one case, I'm dumb, not stupid Thanks for the reply, I was just checking the reamer out, not running a full batch. The question in my mind is if the reamer opens the case so large that the bullet falls thru, what's the purpose of the reamer? Use the reamer before sizing? That doesn't make much sense to me.

Don't ream unless the cases are too thick! This happens often when necking brass down from one size to another, like 30-06 to 25-06. A tight custom chamber will often require thinner brass in the neck. I prefer to turn the outside of the necks to make them thinner and round at the same time. Inside reaming doesn't make the necks round.

Another reason to ream is to remove the "doughnut" from inside the case neck.
Here is a great article on that and other case prep items.

That is one fantastic article. I won't even start on that for my 1500 brass I use for prairie dog shooting, but the 50 special target shooters will get some of that treatment.
