Just started reloading rifle ammo. Need to pick up a case trimmer. I do 200~300 in a batch. I'm thinking in terms of a manual trimmer with an electric drill attachment. I don't really feel like spending $300 for a Gracey. Any suggestions that would shorten research time would be valued. Thanks -
HAPPY FIRST DAY OF SPRING - now go plant your tomatoes.
Lee Precision is a good source.
1. Buy the trimmer that has a wooden ball handle and it will be very comfortable.
2. Buy the attachment that allows you to use an electric drill.
3. Don’t forget to buy the case length guide. It attaches to the trimmer and gives you an accurate cut without meauring anything. Do make sure that the when you put the case in the drill attachment the drill attachment is secure around the base of the case.
4. The chamfer tool by Lee should be used manually and it requires only one half turn on the out side and one half turn on the inside (there are two cutters for each position). Don’t overdue the chamfering.
5. Total time for each case is about 4 seconds and it is very easy to do. IIC the toal investment is about 15.00 to 20.00.
6. Unless you are shooting at very high pressures, cases generally do not need to be trimmed after each use. Or if you a a bench rest shooter, you may need to, but that is a different thread (and a long one, to boot).
Before you trim... and this is from direct experience...
1. Resize the case (unless you shoot a single shot).
2. Reneck the case.
Both of these operations will increase the length of the cartridge case and if you don’t do these things, the case will come out the wrong length.
Most of your trimming will occur when you have new, unused cases sold by the bag. The trimming that is needed for working cases is quite small and I just do them manually to save time.
All the above equipment can be purchased through Midwayusa.com at really good prices.
Let me say this again. This not an area in which you need to spend a lot of money.
Good luck. If you have any questions, freepmail me.

Yep. All done at same time, trim-debur and chamfer.
