This is not a knock or a shot .... but im guessing that, given your admitted "varying OAL", amongst likely other varying dimensions, your 100% track record with personal handloads versus your reported (substantially) less reliability with Sig and Underwood factory ammo, that the cause of your observed differences in overall reliability might likely be attributed to .... luck.



Stay safe!

Aw man I love it!!!!! Thank you for sharing! The 10mm will smack the deer. I have taken three deer with 10mm's. Works quite well.

Just a quick update to you all ...

As I type this, first-light on opening-morning here in KS for firearms deer is about 8 hours from now.....

I wanted to update you all though about my recent range trip. A week or so ago I loaded up a few Accurate #9 ladders using the new and simply AWESOME new WFNPB .402" boolits I bought from my now favorite boolit mfgr, Montana Bulletworks. On Saturday, I went to the range to test them out (for accuracy only, as it was all I had time for with my upcoming hunting trip and other recent life obstacles). I don't have much time to go into much detail right now as i'm literally in the car right now, en-route to Western Kansas for my highly anticipated deer hunt on a friend's private land.

Test firearm was my beloved Glock 40 MOS equipped with a Black Satin AlTiNi coated 6" KKM specially throated by KKM for these exact bullets / 3 MOA Vortex Venom / Dawson & Ameriglo co-witness irons / Ghost Edge 3.5lb trigger w/ Wolff lightened competition springs / Match Grade Slide Lock.

I ran the following loads under he aforementioned 200gr bullet using mixed brass and CCI300 primers:

- 8.5gr Longshot
- 13.0gr AA9
- 13.2gr AA9
- 13.4+ gr AA9
- 13.6gr AA9
- 13.8gr AA9
- 13.2gr AA9 (moly-coated test samples that Montana Bulletworks kindly sent me to give them feedback on, which I will surely do post-hunt!)
- 13.2gr AA9 under 200gr Beartooth WFNGC
- also tested a few of Federal'a 180gr JSP Troohy Bonded rounds to see how they 'felt' and shot overall.

NOTE: I wanted to run blue Dot load (~11gr or so) but didn't have time to safely work that load up so I passed for now.

All of the above mentioned loads fed and functioned flawlessly and ALL were extremely accurate.

I must have done everything right this time because not only was there absolutely zero leading... But all of the loads over 13.2gr left the bore downright shiny ... just as it was prior to firing!! (I'd read about this happening when you get everything just right but was amazed and overjoyed to see it firsthand.). 

Note: I used a bore snake every two loads and strings were only 10 shots or so per iteration.  This was not only to keep track of which loads landed and which did not, but to maintain accuracy throughout the test.

I will say that it was difficult to tell which load was most accurate as I was not only pressed for time but, not surprisingly, found that the groups I fired near the beginning of my range visit were the most accurate and group sizes slowly (but surely) deteriorated  until when I decided to quit for the day (for that very reason).  lol.  Also interesting to note was how the loads felt from a 'power' perspective. Up through  about 13.4gr AA9, all of the loads felt very stout but also fairly normal, considering the Glock's large recoil-absorbing frame, however, The 13.6gr 13.8gr AA9 loadings, however, felt substantially more powerful  - with the 13.8gr AA9 loading being the single hardest recalling 10 mm round I've ever fired (in any 10mm), which to me, sends a strong message.

Overall, it was an enlightening and interesting range trip and one that I will soon repeat at a later date when I have more time, my other 10mm's .. and my chronograph -- and hopefully, by then, my FBI sized Clear Gelatin blocks. Another day....

That said, i'll be out in the woods for the next five days on private property hunting Whitetail with my Glock 40 10mm... CANT WAIT!! Weather should be perfect, highs in 40's, lows in the 20's ...  Wish me luck!! ...and good luck to everyone else!

Stay safe!!

FWIW I've shot 11g BD under a 180gr XTP a jazillion times. Would you trust data from the manufacture of the powder or some other company? .  (that said, still do your safe work ups).

Nice!!

Nobody?   

Since I started reloading I have used "primarily" aftermarket / fully-supported [sic] barrels and have loaded at least 1000 pieces of my brass nearing 20 times.  I toss them out when they get real beat up, lose tension in primer or case mouths, or develop smilies or bulges I don't trust.... or if their OAL changes too much .... if a case keeps looking good, doesn't exhibit any of the "signs" and I don't lose the dang thing.... I'll keep reloading it until it splits, at least in target level stuff.  No reason to throw it out just because it makes it to some arbitrary 'number'....

Stay safe!

Just wanted to say thank you AGAIN to SQL for this amazing resource.  LOVIN IT!!!

More RIA pr0n

Not bad for $629, EH?

I LOVE my RIA TAC VZ 'MS' 10mm ...

To the OP...

I have the DP Co-Witness black-rear / FO front sight set and it works with both the FF3 AND the Vortex Venom optic.... (as I have both, currently running the Vortex on my G40 MOS, as I put the FF3 on my Fusion longslide 1911. 

FWIW, what you experiencing when reassembling is normal.  There are a few ways to get the slide to go on.  (in fact, I hadn't heard of the way you watched on youtube...)...

Method #1. While the slide is removed but assembled (and ready to go back onto the receiver ...), depress the firing pin safety plunger in and push the rear of the striker arm (the one that makes contact with the cruciform plate below during trigger operation) forward towards the muzzle of the firearm until the firing pin protrudes from the breech face, then reassemble as normal.

Method #2:  The trigger should be in it's rearward most position before removing the slide, locked safely back.  When the rear of the slide and rear of receiver are lined up (but otherwise "locked / stopped" so that reassembly is prevented (the condition you describe in your post above)... and WHILE continuing to put rearward pressure on the slide in an effort to 'fully' reassemble slide to receiver, use your third or fourth hand (lol) and push FORWARD on the trigger (which is locked in rearward position still) and the slide should 'click' in and successfully mate to the receiver.



Annnywayyys....  yes, what you experienced is normal for Gen4 firearms that have aftermarket triggers in them, it would seem.

...SPECIFICALLY, using Accurate #7, #9, Longshot and Blue Dot. 

I have lots of experience loading with all of these powders but not necessarily with WFN hardcast bullets.  I am looking for full power and maximum loads you all might have used (firsthand) and liked.

I know the data is out there but if you all could all reply with a few it would be super-great.  .   I'm in the preparation phase of doing a big write-up with new 10mm pistols, new boolits, new optics and other new stuff.... but need to kinda expedite the research phase so i can get all of this done in due time...so any help you all could offers would be much appreciated.  I'll be shooting out of my G40 MOS w/ 6" KKM, Fusion 6" 1911 longslide custom and Rock island TAC-VZ Commander 1911, all of which have excellent, fully supported barrels with conventional rifling.

Thanks in advance!
