back from the range, did some serious shootin'

first 4x20 shots for the competition in .22, offhanded at 25 meter
169
146
146
142 (out of 200)

Not gonna win, just need to shoot another 2 so i got my 20

Then shot some .45 selfloads
them wadcutters are still to light at 8.4grain AA7 powder, they barely cycle and i can tell fom the sooth on the outside of the casing, that they simply don't expand enough for a gas seal..
one of the 7.8 loads was even weaker then it should have been.. it was so weak the bullet went to 25 meter, bounced off the ballistic plate without deforming and rolled back to the firing line, go figure.

The soft loads did something to the gun as at one point the gun chambered a round, it went to battery
but my trigger would not pull, hammer did not fall and the slide seemed jammed when i tried to cycle.
another round, same thing, a factory round, same thing.field stripped the gun, couldn't find anything wrong no change after i reassembled.

Only when i got a snap cap in there did the hammer fall ..
Ran 2 mags of Fiocchi through it, all good again.

Me thinks that the weak loads got some dirt in the trigger mechanism. dunno what else could cause this?

My 230 grain ball with Vitha Vuori N340 was good to go , no problems with that, that'll be my plinking ammo

After that a friend introduced me to the 100 meter rifle shooting.
Shot a 7.5 Swiss , standing, iron sight
first shot was on the card,
then 2 shots from bench rest, got a 7 and 8 out of that.

Also shot a Springfield 1903 in 30-06, standing, got two 6'es out of that

Not bad considering it was my first go at the 100 meter, at least that's how i rate it.. 2012 i plan to get routine done with the 1911, and practice long rifle with club weapons, while i wait for the M1a to be found, delivered, and permitted.

Do you ride the thumb safety with your thumb? Sometimes I will not fully engage the grip safety when I use that grip style. It doesn't happen if I have slim grips on the gun. Maybe your problem is something else but I doubt it is related to light loads.

No, it was a full on jam
Safety would not even engage
The slide only racked with more force the usual

In the garage now, gonna take it apart and see if I can find something more

Check the ejector for signs of rubbing on the top. A couple of my DW's needed a little stoning because of of rubbing there. One locked up much like you describe. A too tight extractor could also cause the jam you describe.

took er down to the trigger , can't say i found any obvious signs of damage or unusual wear.

bit dirty, but that's it.

The top of the ejector :
http://www.cotep.org/forum/attachmen...1&d=1324147613
There is a slight hint of wear on the right edge of the ejector.. not sure if that is what you mean? I mean, it's barely visible..

Ejector looks fine. How's the extractor? Dave has a good post about extractors here http://www.cotep.org/forum/showthread.php?t=566

extractor looks fine too.

It really felt like something in the trigger/safety mechanisme.
It did not jam after firing, it jammed before.
Even after i field stripped, and reassembled.. i racked a fresh round and it jammed again.. so it's not an ejection or feed problem.. the slide was closed, in battery... Really weird..

But on the plus side, i've now gone past the normal field strip and taken it apart to the frame with the help of http://how-i-did-it.org/detail-1911/reassembly.html

That's a great tutorial..

So though it's not clear what caused this, i think it's to do with them SWC's i made.. something was wrong with em.. The gun is fine..

Only thing related to trigger I can think of would be the overtravel screw in the front of the trigger. If it's in to far it will not allow the hammer to fall. Maybe if it came loose something like that could happen.

The screw was fine, it would not explain why the thumb safety also refused to engage.
I still think it was dirt, it happened right after that weak load , the one that bounced back undamaged from impact.

And i did find a lot of flakey powder residue on the rear underside of the slide, the area between the slide and where the hammer is pushed down..

back in one piece, all safeties work, i'm calling it a day.
Now i can focus my attention to that other noble time waster : beer !

I'm sure some will probably have a higher burn rate, but i'm pretty chuffed about my efforts so far. So much in fact, that i've gone ahead and dropped some moolah on reloading gear.

I'm just gonna post this thread, to keep track of my own progress in these matters.

Well, since i decided to quit my previous hobby, eg old Porsches, aka Moneypits. I've sold off my stock of parts... So basically i'm trading one really expensive vice for a less expensive one.. It don't hurt much that way.

So what did i get?

The press.. well, i figured if i'm going to do plenty of shooting, i need volume.
Progressive , people be telling me Dillon, don't look back.
So Dillon it is.

Square B, 550 or 650?
Square B was tempting, but no case feeder... So that's one down with 2 to go, coz i'm lazy
550, No auto indexing...And only 4 stations... That would rule out the use of the powder check die. I like the idea of the powder check die , might save my bacon one day..

so there we go, 650 XL... It arrived last monday.
Carbide dies
case feeder

So far i've figured out, that i should not have gone cheap and figured i'de mount it as is.. It's a royal pain in the ass to keep such a big thing steady..

Strong mount already ordered to cure that problem
also got the Dillon powder check Die
couple of Dillon 100 rnd boxes
spare part kit and decapping pins
Lyman 1000 xpdigital scale
Lyman pro 1200 tumbler
kinetic bullet puller, primer flip tray

1500 fiocchi primers,
accurate arms powder #7 (all they had in stock, we don't have gun supermarkets here)
and 500 HN 190 grain semi wadcutters.

Hope to get the mount early next week, but in the mean time with some clamps i can start getting a feel for the thing.

I test one station at a time.. the decapping was first.. pretty easy really
The only tricky part is that it sometimes doesn't go square in the shell, of the rig wobbles to much , strong mount will cure that.

The re-priming station... ain't rocket science either... just need to start counting the number of pulls till the first primer comes up ...

As a test i primed 15 rounds, fired em off in the gun
then ran those 15 rounds through again, decapped, reprimed..
i love it.. The cheerful "plink" when yet another round ejects into the basket...

this might become an addictive thing... Like a one armed bandit , except it's a Blue one. :D

Next week, the strong mount, final setup, and the first loads..

Hey, you live in Ypres, that's where Paschendale was fought. I'm a big military history buffClyde

Sorry for the Hijack:p
