Adjusting Windage affect Elevation? WTF?!?! Wasted so much time today zeroing the gun. Make sure you adjust the windage, tighten up the retaining screw, then adjust the elevation and reconfirm.
Someone needs to make a modern big lens red-dot alternative to a C-More. *sigh*
I recently found out that there was a company who’s making 170mm magazines that is purported to be able to fit 30 rounds of 9mm ammo so I decided to purchase one to give it a try.
Company is called MBXExtreme.com and they currently have four models of magazines 170/140 in 9mm and 140mm in 40S&W and 140mm in 45ACP.
According to the website, the 140mm 9mm magazines can hold 24 rounds and 170mm can hold 29-30 rounds.
As you can see from the video, I could fit 30 rounds in the magazine but not without some help. I think it’ll get better after “breaking in” the springs.
It is still not very clear to me how beneficial 30+1 rounds would be for me as most stages are around 30-32 rounds max especially with the stress that it puts on my grip. Perhaps it would be most beneficial if it was 31+1 for a maximum of 32rounds in the magazine.
I have a match coming up in a few days, I’ll take it out for a spin and report back with another video.
Finally got to the range to sight-in the C-more sight that I replaced recently. You can see from the video that the new 9mm Major CFE Pistol rounds I loaded is much more consistent and accurate. Excited to finish off my HS-6 loads and start using the CFE rounds.
Bought a new Competition Electronics Chrono from Amazon and managed to get out to chrono my 7.0gr CFE Pistol rounds. Here’s the report using my old 8.1gr HS-6 as a benchmark. Looks like the 7.0gr is a winner for me at 172pf.

With regards to my previous chrono session (9mm major Chrono results with Hodgdon CFE Pistol). Here’s an update. I went to chrono the rounds I made using CFE Pistol at 6.8gr of powder using a different type of Chronograph. The first session was using a Chrony but this session I was using a Competition Electronics chrono so the results are a little unexpected. I should really stick to just using one Chrono.
As you can see i’m using my typical 8.1gr HS-6 as a calibration round. this time the results were really low at average 1323fps, that puts me at 164pf which is under the power factor floor. The deviation is huge too which could mean that the rounds were loaded inconsistently.
CFE pistol on the other hand, metered VERY well. the SD is only 6 and the 3 averages of 5 rounds is 1363, 1357 and 1351. Super consistent. I’m liking this powder already.
The average is 1357fps and with a 124gr projectile, that puts me at 168pf.
I trust the Competition Electronics chrono more than the Chrony so I’ll bump it up to 7grs of CFE Pistol hoping to get around 170-171pf. The old result using the Chrony at 7grs gets me to 172.5. The Chrony is a little “exaggerated” in terms of fps so 7.0gr should put be at 170pf with the Competition Electronics chrono.
7.0 it is!
During my Chrono session, I discovered that my sights were off by 3″ to the left and 4″ high!! That explains a lot now. I realized something was a miss during the all steel stage at the recent Northwest Challenge when I took 10 shots to bring the steel plate down.
At the Chrono, the groups were all off so it was clear what was wrong.
That would explain why I’m tagging a lot of no shoots and tanking stages recently.
I’m not sure how that happened but I’m suspecting the crack in my cmore is contributing to the problem.
I’ve adjusted the sight now but haven’t tested it yet so I better find some time to get to the range again to try it.
*sadface*

Guess I can back it down to 6.6 or 6.8.
ShockBottle Case Gauge by BanksBullets.com is a tremendously useful reloading/handloading tool. It takes the drudgery of case gauging or chamber checking every single round before putting them away. In this review, I show you the two major benefits of the ShockBottle Case Gauge.

Love this series of videos made by AmmoForSale.com. Taking a tongue in cheek look at the two most popular handgun calibers in this country and how one is better than the other.
Obviously the 45 ACP has my vote. checkout the video : (http://www.ammoforsale.com/.45-acp-ammo-for-sale#video)
And the 9mm “Euro-pellet” HAHA! (http://www.ammoforsale.com/9mm-ammo-for-sale#video)
