Home Forums Hunting & Shooting Handguns 40 ammo in a 10mm ?

Was shooting today doing some final chrono testing (confirmation really) of a .40 load that is going to be produced. It is one I have been working on for literally over a year. I passed the 2K round mark in testing and am very happy with the results.

As an aside, while I was out, I put some of the hot .40 rounds through a Gen 5 G20.

They ran through the gun perfectly, just as easily as they ran through the Gen 3 G22.







In my experience .40 S&W has not generally been a particularly accurate cartridge, (excluding custom race guns) and especially when paired with Glocks. For years I generally skipped shooting it (with the exception of when the agency I worked for issued .40s). I preferred 9mms or .45s.

Long story short, I have spent a significant amount of time working on an outdoors/hunting/defense type load that delivered the combination of top end velocity, excellent reliability, and great accuracy.


Today after I shot 50 rounds for the chrono, I shot a couple of 5 round groups over bags.






For a stock Glock barrel, I will say that I am very happy.
