My son's first novel.  It's not Tolkien, but it's OK.

I don't know that you are being fussy.  I agree that it would be more "readable" if the message body was not included.

But this isn't "search" driven.  It is controlled by the board index settings.  Here is a screenshot of the options from the admin a console:

I can't find any settings to control the "recent" posts page.  But I will keep looking.

There isn't a button in admin to remove the message, but I agree that would be cleaner.  I will see if I can find a mod for it, or if I can find and update the code.

How about this:

Also now at the bottom of the forum main page.

It is amazing the impact that small change can have.  .015" is two average human hairs.

yeah...I didn't comment on that but when I first say it I had the same thought and wondered if a falling bullet had gotten to them.

I will look at it some over the next week or so.  I found one add-in package that looks nice, but it may not work with all the available themes.  I will deploy it to my test environment and see how well it works.  If the package works well I will schedule a change to apply it here.

A few years my family started receiving our CMP USGI surplus 1911's. This has spawned a fair bit of 1911 shooting. During this journey I looked into the pistol qualification requirements at the time these guns were entering service in WWII.  I found this:

This weekend we set up some two target stations and had a go at the qualifier. The shooters were my mom (79.5), me (55) and two of my sons (22,19). The shooting, if you aren't aware and haven't watched the video yet, is one-handed shooting.  Total course of fire is 45 rounds over 9 strings of five shots each.  Scoring is a combination of normal scoring + hit/miss scoring for the "quick fire".  Final score is an average of the percentage from slow, rapid and quick fire.

We were shooting 220 grain SWC over 5.4 grains of W231.  This is a 875 fps load and shoots pretty easily.  It normally feeds fine in these guns, but we did have a few malfunctions here and there.

Mom and I shot first.  Mom's heart and mind were in it, but after the slow fire strings her elbow was done.  She is only 4'10" tall, 120 lbs and nearly 80 years old.

I finished out the qualifier alone.  Then my two sons ran through the course.

Mom scored 29% on her slow fire string.  Room for improvement.

I scored 94% in slow fire, 57% in rapid fire and 93% in quick fire for a total score of 81% - Sharpshooter. I tanked (or mis-scored) my second rapid fire string, and it cost me "Expert".

The boys got 43%/56% on slow, 29%/42% on rapid and 40%/67% on quick for overall scores of 37% and 55%.  Both commented early and often how "wrong" it felt to shoot one handed.

All in all a very enjoyable time.  Next time Mom will shoot the Rapid Fire stages and the rest of of will hopefully shoot "better".

If you are looking for a fun time, this challenge is it.

You are right.  Old man brain got me.  Speer.  I amended my post.

Some time back I bought about 500 of the 200 grain Speer Gold Dot HP bullets. Many thanks the Wade for hounding Speer until they released this as a component.

Despite having them on my shelf for many years, I had not really worked up a load for them.  This weekend I was able to start that journey.  I had 20 loaded up with Longshot.

Specs:
10mm Auto Starline brass, once fired
Winchester Large Pistol Primers
8.0 grains Longshot
200 Grain Speer GDHP
1.260" COAL
Dillon 550 press with powder drop

Test Conditions:
85° F - Sunny
7,400 feet elevation
25 yards
Witness Match 5" barrel
Sitting, two hands, no mechanical rest
Labradar
10 Shots

Velocity Results:

Average	1117.24 fps
Highest	1140.69 fps
Lowest	1082.95 fps
Ext. Spread	57.75 fps
Std. Dev	17.23 fps

Accuracy was not really in scope for this test.  I didn't have time to set up the bench and I am not the greatest shot without a good rest.  Still all 10 shots would have been "A" zone hits on an IPSC standard silhouette.

Brass looked fine.  Hodgdon lists 7.5 grains max with a RN Lead bullet for 1141 fps and 8.2 grains max for a Hornady FMJ for 1172 fps.

I will test the remaining ten for accuracy next time I have the bench set up.  And I plan to load up another 20 rounds at 8.2 grains I expect another 30-40 fps from that increase.

Glad they caught it!  Hope you have a speedy recovery!

All my testing this go was the Ginex primers.  Sorry if that wasn't clear.  The high SD/ES group was with mixed brass Ginex, the low SD was with all Winchester.  I picked winchester as the headstamps were easy for my tired eyes to see in a box of 100.

Last night I sorted out four boxes of 100 - Winchester, Federal, S&B and TZZ. Next week I will load up all these and then get some statistically significant samples of data.

I mean on the one hand I know the answer.  Top shooters don't mix headstamps for a reason. But the data nerd in me can't help but independently verify.

My second son lamented to me last week that "pistols are really hard to shoot".  So, we spent some time in dedicated accuracy training on Saturday. In addition to helping him with shooting, I wanted to figure out an issue with my Witness Stock III in 9X19.

The story of how I got this pistol is out of scope, but it has never run 9X19 quite right.  I also have a 38 Super barrel for it that works very well.  When shooting 9mm it runs the most or all of the first magazine fine.  But always before the end of the second magazine it is hanging up about 1/4" out of battery pretty much every shot.  And it isn't a "bump" the slide situation - It is locked up tight, like the brass is out of spec.  But it's not, brass is fine and if you clear the gun, and reload the exact round that was stuck it loads fine. I think the chamber is on the "tight" side and as powder residue builds up it causes a clearance issue.

Sure enough about half way through his second 5 shot string the issue manifested and by the end his fourth string it was every single shot.  Stripped the gun down and sure enough, factory ammo would not pass a "plunk" test.  Rounds could be pushed into the chamber with minor pressure, but they would not fall in and out. I was thinking the reamer fairy might have to visit the gun. 

Then I had a thought...Swap in the RSA from my Witness Match in 10mm that had a stiffer recoil spring.  A glance in my range bag revealed a 20lb spring just hanging out, so rather than steal from the Match, I just put in the 20 lb spring.

We ran another 150 or so rounds with out so much as a hiccup. It seems it just needed a little extra "help".  And, to be honest a 20 lb spring is probably more appropriate for the 38 Super Comp loads I run.

As far as my son's shooting;  He had a little issue with trigger control.  I feel like a bad coach for not noticing this before, but he took the concept of trigger discipline to a whole new level.  He was keeping his trigger finger on the side of the frame until he was ready for the gun to fire, then trying to move from frame, to trigger to shot in one smooth, nearly instant motion.  I clarified that once his sights were pointed down-range and he was in shooting position, he should gently rest his finger on the trigger, do his final sight alignment and then just increase trigger pressure until the gun surprised him with a shot.  His 6-8" groups that were low-right almost immediately became 3-4" groups clustered around the center of the aim point.  Another couple sessions and he will surpass me.

**Very Preliminary Findings - Limited Data Set**

Saturday I was both doing some training with my second son who wants to shoot pistol better and doing some chronograph testing of some handloads. The test docket included velocity verification for a 45 ACP load.  The load is 5.4 grains of W231 under an NOE 453-197 SWC.  That bullet weighs 210 grains with powder coat in my alloy.  I have used this load for some time, but recently changed from CCI to Ginex primers so I wanted to re-validate.  Loads were produced on a Dillon 550C.

The first 5 shots averaged 927 fps, dev 15.8 fps, spread 38 fps. There was no velocity "cluster".  Gave about a 4" group at 25 yards two hands off a folding table, no bag.  Generally I will measure the "best three" but there really wasn't a best three.

To be honest I was a little disappointed in the accuracy...I am sure the pistol can shoot better than this, and I felt good about the shots, so I didn't think I was the problem.

My son shot a 5 shot string, with similar accuracy results*.  These were not chronographed.

On a whim, I loaded up 5 more shots all with Winchester headstamp.  Turned the labradar back on and gave it another go. This time the average was 953 fps, deviation was 10 fps and the spread was 20.  And this time I had three shots within 4 fps of each other (958, 961, 962) and two that were 942.  Group size dropped to 2.5", with three shots in about 1.25".

Two 5-shot tests do not make a statistically significant trend.  But the results were enough to inspire me to at least re-sort the brass into headstamp groups. And I am planning some more targeted testing by headstamp.

Generally I have considered minute of soda can "good enough" for pistol ammo, so I have not really sorted brass as the juice wasn't worth the squeeze.  But a new game has emerged at the cabin - The Roma Challenge.  When a tomato goes over the edge, it is placed on a stump on the side of the mountain.  The stump is 25 yards from the deck.  The challenge is to hit the tomato standing unsupported from the deck.  A roma tomato at 25 yards standing with a pistol is a small target, so "minute of soda can" isn't going to cut it.

I will report back once I have generated a larger data set.

*After a bit of coaching my son was shooting pretty much on par with me. He needed some coaching on his trigger control and his group size dropped from about 6-8" at 25 yards to 3-4" with 9mm Armscor 115 FMJ.
