I'm not sure but it might be a "muffler" for a turbojet. Way back when, there was some experimentation using narrower exhaust passages to cut some of the low frequency noise coming out of the...

I'm no chemist, but I look at it this way. The amount of vapors put off from a liquid are primarily determined by the vapor pressure of the liquid in question and the pressure at the surface of the...

I reckon one with bullseye in it does pretty good too.

I'd also be willing to bet that a percussion cap and a paper tail might make for some interesting adventures...

Just sayin'... :oops:

I'm not sure what exact measurement you are after, but on the 22 die I have I get:

Expander portion (main): 0.2219"
Step diameter: 0.2263"

Boric acid fluxes work BUT...

They leave a residue in the pot that is very hygroscopic and will cause rusting if it is not removed (at least in humid areas). The residue is also very tenacious in...

If you ever decide to take the magazine release out, that little doo-dad on the off side that looks like a screw - isn't. Depress the release about half way and gently turn 90 degrees with a...

I tried one of those NcStar "things"... Never again. The ocular lens came loose and rattles around quite a lot if I try and have the focus set anywhere but "tightened up". Fortunately, it's not too...

I've got every single gun that has ever come into my possession. I might rework one or two but sell one...nope. About the only way one will ever leave is as a gift to my son later on or an estate...

I've got a DPMS LR308 with an 18" barrel and a Miculek brake. It will definitely get your attention when you pull the trigger. The brake is very effective and recoil is almost non existent, but...

My thoughts on the matter:

From a pure perfect world physics approach, the area of the case head multiplied by the maximum chamber pressure will give the maximum bolt thrust that can be obtained. ...

If you have an older one, the seal is not neoprene, but leather. Take a little care not to bugger it up and it works just fine. I recently had one of the leather seals give up and the folks at...

I'd go with BABore's suggestion. I know it's not a 45/70 but I really need to watch how I charge a 223 case with 3031. My go to load for that will fill the case completely if I don't slowly pour it...

Try making a flaring tool for the checks. It adds a step, but makes the check seating process much easier if the checks don't go on the shank easily. I did that for the first time when I opened a...

I bought some Privi ammo for my 91/30 just to get the brass. The bullets measure .311'ish and my bore slugs a little better that .314. Needless to say the Privi ammo did not shoot too well but it...

To fix the problem of really tight gas checks, either from small checks or a shank that's a little oversize, flare the checks. There are several ways to do this. I use a piece of cold rolled steel...

As has been said, the sprue plate gets a bit too hot to contemplate opening it without gloves. I prefer not to beat on my molds if I can avoid it.

Mine must be good to go then. It will support my 270...

I've seen it too but I'm not sure why. I've got a P238 (brand new) that will do that if I hold it a little limp. Get a good firm grip and there are no issues. I have not shot the gun much though...

My opinion so...

Don't lube the part of the pins that sit inside the cavity and actually form the hollow points. You do want to put a small amount of lube on the guide rods that hold the hollow...

The long die works for 30-30, but just barely for me. The plug has to be screwed down to the point that the lock ring is not quite engaging all the threads. Just don't get ham handed with it and...

Cutter,

I went through a similar situation with the thermocouple mounting on my Lee 4-20. If you look at what is happening with the jam nuts on the bottom cover you will find that you have made a...

I was one of the tail end Charlies - but I don't mind a bit. Just got my invoice & paid.

Thanks & looking forward to a really nice mould.

Well, there's the NOE 316299 small buy going on right now at around 200'ish grains plus a little bit. Might be a little while before they are done though and it's only advertised as 0.316". I...

I'll take a 4 cavity. NOE makes an excellent product. I've got three with 4 more on the way counting this one.

Yep - what Bill said... For purely anal retentive reasons I put the washer on "tip" up against the screw head. If the hole in the sprue plate is big enough that the washer tip is not making full...
