I hadn't seen the one Andrew has linked to when I bought this one, the clear tube to catch the spent primers seems useful. I don't have any issues really though just having a bin in front of me and holding the de-primer upside down over the bin, the primer and unburnt powder drop straight into the bin. On similar reviews of this deprimer I've seen people using small tubs to drop the primers into.

Frankford Arsenal depriming tool

If you know someone with a lathe you could have a new deprimer pin turned down to fit, but the standard one it seems will not

I think when it comes to watching TV and doing reloading - I'm with you, but with decapping, I don't think there's much risk of doing too much wrong.

There are several ways to skin this cat-primarily the decision is whether to (sonic) clean brass-in particular the primer pockets -first.

Should I go for carbide with the higher surface speed to avoid low RPMs? Can the Chinese spindles handle low RPM or do they loose torque? Can hobby CNC machines handle the high feedrate? Can I follow the toolmakers recommendations on these types of machines?

Harvey deprimervs Frankford Arsenal

To explain how I'm calculating each value, I start by finding spindle speed from the surface speed and tool diameter. Then I find feedrate from the spindle speed, chip load and no. flutes.

Seems like a simple tool and easy operation, but why would you decap (deprime) on its own and not decap and resize together?

I'm never very sure about 'saving time'-a few seconds per case?-but some may be,and I'm not sure about 'watching TV' while doing any reloading!

US Forum posts and a couple of reviews suggest not-spare pin assembly and grind down,I suppose-but it's not entirely clear,and some are refering to Lapua 6PPC....or early production etc....so probablynot,but an easy fix available.

The 204 in the Lee die is a chore with the Hornady brass. I've buckled a few and at the price Hornady is asking, I found it really annoying. This little tool automatically centers the case, you can't miss.~Andrew

I usually do but when doing sub calibers I get nicked case mouths from miss alignment every once in a while. This Frankford aresnal has never mis aligned with (so far) my 204.~Andrew

Very new to hobby CNC so still getting sorted with the whole speeds and feeds thing! The trouble I'm having is finding consistent or reasonable numbers for things from the internet! I have a little experience with larger machining centres but I'm not sure what hobby machines can do!

...and I think fiddling with getting the decap pin centred in the primer hole in other designs would spoil any TV program.

I picked up one of these Frankford Arsenal tools. There is an adjustable bushing in the decapping chamber that allows you to automatically center the pin on the primer. The primers are caught in the clear tube and the cases are auto ejected. $34 US and a real wiz on depriming cases. Very fast.~Andrew

The additional benefit is that my lee turret die doesn't seem to pip primers out in the same place twice, which generally means having to pick up half a dozen or more used primers after a resizing session. This tool is a little more consistent with where they go. Add in that it can be cleaned (Inc. Primer pockets) before it touches the die which means cleaner dies.

I've taken to single repriming with a couple of sinclairs (one at a time,different shellholders!) and compared to the Lee Auto,it has a 'feel good' factor ( not to be confused with a seating depth feel factor).

I quite like Andrew's option,if I could be 100% sure it didn't spray burnt powder etc on the custom cream couch,or drop used primers down the cushions...:-) .....as the others seem far more likely to do....

When it comes to fiddling, once you get into a rhythm it becomes very easy to repeatably find the flash hole, the first few always seem to be a fiddle, but the "knack" comes fairly quickly.

When using the higher cutting speed I then end up with a high feedrate of 1336 mm/min. Can hobby CNC machines handle this kind of feedrate into aluminium? Can I reduce tool load by taking thinner cuts to obey the feed and speed requirements? How do you work out a suitable depth / width of cut? Ive been told that I want to make cuts with a width of about 1/4 of the width of the tool and depth of the width of the tool (so for an 8mm bit I'd cut 8mm down and 2mm wide.)

Best depriming tool

The issue I'm having is that the values I get are either very high or contradict the rest of the internet. For cutting aluminium wikipedia recommends 75 m/min (246 SFM), which with an 8mm tool yields a spindle speed of 2980 RPM. That seems very low to me considering the spindle I'm looking at buying is 0 - 24,000 ! (Do the chinese spindles drop power at lower RPM?). Looking at the SECO tool brochure they suggest a cutting speed of 400 - 650 m/min (>1312 SFM) which is massively high and yields a spindle speed of 15920 RPM! Is this the difference having carbide tooling gives? How sensitive is cutting speed - is this something I should obey or a very loose suggestion?

Never done it with a .308, but in my .223 when using the die I malformed at least 2 case necks by hitting them with the pin and wrote off the cases completely
