The Lee APP press and the sizer dies made for it work so slick I really intend to use that method any time I need to size a PC or other bullet type.
They make about any dia I could ever think of...

I do not doubt that John. Being able to look at a tool, even a new tool and have idea if it will cut or not IMHO is a good skill :-). I have looked at brand new cutting tools at work and known...

In past jobs we used a lot of taper reamers, they are a pretty simple concept really. More detail than your question but any that I have made or sharpened were simply OD ground and then backed off to...

In the lathe this is what I use to make the crown.

Looked for a picture real quick and failed, just a 1/2" dia rotary file with a 1/4" shank, run lathe really slow and use it by hand. It cuts...

I know you know ;-) but for others one key thing to machining a new material is to look up the speeds and feeds and make sure that the work or the cutter is running the correct speed. I machined...

I tried gluing sights onto an H&R topper 20 gauge when I was Oh I dunno 19 years old. They kept falling off. Loctite black max did not exist back then though.

One issue is that parts of the...

I found an earlier thread that covers this.

OH, it was your thread back in 2021 too ??

I have a 22-250AI that is a non saami reamer, it will not accept brass made from 308 or the like. I always encourage folks to look at the SAAMI drawings, they are not terribly hard to find and or...

I wonder if 260 rem brass would work better ?? I made up a wildcat AR308 setup where I ran a 6mm creedmore reamer in deeper to create a kind of 243AI that I use 243 brass in.

There were a lot of folks doing "357 AR" long before the 350 legend existed. Starline made "223 basic" brass which was about the best way to do it but people were dilating 223 brass before that was...

Sometimes it is useful to dig into the SAAMI specs for chamber and cartridge. Older stuff when I look there seems to be a wider range between minimum ctg and maximum chamber. The 7.62x25 could be...

I have not tried it yet but did read that Woolite was good for washing lanolin off of things it had been applied to.

In a wet tumbler with stainless steel pins plain old Crystal Lite lemonade drink mix works GREAT to clean brass cartridge cases. I follow with a rinse with plain hot water, then a rinse with a...

Somebody I know reloaded a steel 45 acp boxer primed steel case many many times and it just kept on working fine.

I have used Clays and it worked fine to blow 240 Ackley out into a 375 straight wall case. Clays, small piece of toilet paper, than filled case with corn meal, had corn meal did not have cream of...

For 7mm TCU which is a 223 blown out to 7mm in a TC contender one can just fire 223 ammo, the 223 bullet we would hope never touches the 7mm bore, it seems to work fine really.

It might work just fine with the 9x19 barrel too. There are a fair number of 9x19 conversion barrels made for other guns that use the 40 extractor and work good enough to practice with.

So is it required to buy the $60 kit and a $7 punch to do LR for example ?

I agree, that is the "good stuff", works great on motorcycle carburetors. I wish I could find it at the retail level. I have not looked to see if it is good to go on brass and bronze tho but carbs...

I wonder what a 38 shortest possible colt would look like ? Shorten and inside ream 38 short colt to get the shortest possible ctg. Would it end up 100% loading density with Clays ??

Any product that mentions the "pores" in metal is snake oil IMHO.

My dad loved to point out that the Bridgeport was actually a pattern makers machine tool in it's beginning, then the tool and die makers found out about them :-).

We have a molding department where I work, the molding presses are 1000-2500 ton, tooling gets heated to 350F. At one time we used vacuum for some tools and parts so we had 3 big vacuum pumps in a...

The very first thing I ever swaged was some .357 using a set of reloading press dies borrowed from a friend, I swaged some previously cast and powder coated bullets. I was able to even run them in...

Indeed grade ZZ are not good enough. The closest tolerance stuff we did in that shop was .0005 total really, and in a practical sense that is really as close as real world things ever NEED to be. The...
