Saturday evening, still hot and humid

so if you don't have somewhere to go, stay cool indoors.  Data to check over.

About that brass processing,

since I got the Lyman rotary tumbler here's what I do:
Get home, throw the brass into the old vibratory tumbler to clean powder residue and such.  Picked-up cases are sorted and run through separately.

Bottleneck cases such as .308 and .30-06 I lube and resize, then measure.  Any that require trimming are trimmed.  These are set aside until there's enough of them for a load in the rotary.

Straight-wall cases(.357 Mag, .45-70, .45 colt, etc.) are checked over.  Then, for most of them, I use a depriming die to punch out the primer, then set them aside until enough for the rotary.  They rarely need trimming; those that do get it now so they'll be ready to load.

Cases intended for general practice I take no special pains on.  Cases intended for serious shooting I sort by length, or pick a lot and trim them to exact length before loading.

That's my process.

Finally, some range notes

On Blackhorn 209:
Did some checking around, and decided to start with 33.0 grains under the 500-grain Lee bullet.  Three variations on this:
Resized cases*, wad under the bullet.
Resized cases, wad under bullet and about 1/4 sheet of toilet paper under that as filler,
Black powder cases, same filler.
All worked.  The group with resized cases and the filler grouped better than without filler; the black-prepped cases a bit better yet.  According to data gathered, I can safely increase the charge up to 35.0 grains**; that would eliminate the need(such as it is) for a filler, and I'm going to work up to it.

Velocity on those loads was very close to that given by the compressed charge of 2f black.  With, as noted a couple of days ago, no need to use a blow tube between shots, or wipe the bore every five-ten.  The wiping being a pain because you have to remove the tang sight so the cleaning rod can go in.

Some vertical stringing with some loads(couple of black and Blackhorn), which- until I can try them again- I'll have to blame on myself; the velocities were fairly consistent on the black, very on the Blackhorn, so almost certainly my fault.  If there were a simple way to put a scope on this rifle for load testing, I'd do it to eliminate such error as much as possible.

So that's the results on that.  Spent a little time after the shooting was done scrounging for brass, and I've got to finish processing that stuff.  And loading some other stuff.  And more .45-70 for next time.

*I only resize the first half-inch of the cases; that works the brass as little as necessary while providing consistent neck tension on bullets.
With cases intended for black, I don't resize at all; only flare the case mouth enough to allow the bullet to slide in cleanly.
Both of these work because the cases are being fired in one rifle, so don't have to worry about any chamber differences between different ones.


After the scandal involving the ejection of Jewish women carrying Star of David pride flags at Chicago’s Dyke March on June 28, a sister organization in the city has announced that it will follow suit by banning “Zionist displays” from its upcoming protest against sexual violence and “rape culture.”

The ban was announced this week on social media by the organizers of SlutWalk Chicago — part of an international protest movement that “fights rape culture, victim blaming, and slut shaming.” The Chicago event is set to take place on August 12.
Wonder when they'll start issuing their more devoted members some snazzy armbands?

"But lying under oath and submitting false documents and violating borders is different when WE do it!"

From Madam Hoyt:

Enter Marx and his “scientific socialism.”  It wasn’t.  And frankly, anyone who looked into Marx -- who not only didn’t know science from a hole in the ground, and who had many of the things he wrote about already wrong as judged by his contemporary economists -- would have known it wasn’t scientific.

But people wanted to believe it was possible, all the more so after WWI turned Europe into an abattoir and planted doubts about Western civilization.

Scene from the range

A bit more blunt than what the guy actually said, but I think covers it:
"No, you can't shoot your new AR.  Because while it does have a rail, you didn't put any sights on it.  And you're not allowed to shoot something without sights.

Also, what drew our attention to this is that you were rapid-firing said rifle.  Which is strictly against the rules you read and signed off on.

Refund?  Because you're a dumbass who brought in a rifle with no sights?  Really?"

This is about the third time I've seen this.  One guy had a brand-new AR variant chambered in .30-06, and wanted to try it out.  WITHOUT SIGHTS.  What the hell are these people thinking?

It's Friday, and still hot outside

Therefore, stay inside and get to studying
