Odd. I’m just a Gold Dot across the board. I don’t put too much thought into Pistol ammo other than bullet weight for the caliber. And even then, I don’t dig too deep like the ballistic forum nut bags.
Does seem a little slow to me as well. I have a variety of Gold dots and Critical D ammo. Since Mark obsesses over handgun ballistics, I guess we should chrono several loads and just skip shooting the new Tikka Tx3 this Saturday.
In all seriousness, I am curious how Horndog HD ammo is running the same as my 147gr range ammo. Ok, we will shoot out of the Stacatto 4.4 inch barrel. Ron, was yours plus P+ variety?
Seems a little slow. I never chrono’d it, but I got a bunch of this like a year ago. Seemed slightly light, like much of Hornady’s not+P duty-oriented ammo. An assumption about its velocity was made, and some friends and I started shooting it suppressed with G19s. We quickly realized that much of it was supersonic and loud as hell.
Correction: the stuff we were shooting was a training round, and is thus irrelevant to this convo.
I’ve learned that Beretta’s typically have generous bore diameters. The purpose is often guessed that it’s to reduce pressures for longevity and increase reliability with low-quality ammo.
I found lots of guys using cast .358 dia. bullets. So, get the right shaped bullet and fire it from your .38’s, .357’s, and some 9x19’s.
And yes, I found other chronograph tests reporting sluggish velocities compared to other standard-design bores of similar length.
I measured the groove dia of my pistol and found it was .365.
I pulled and measured a Critical Duty bullet and as expected got .355.
This ammo averaged just under 1100 fps from my AP5P.
My Beretta had an oversized bore (grooves) apparently. It shoots everything slower than comparable-length barrels. This one more than others.
However, it shoots accurately from both guns. 4-inch 5-shot groups free-hand at 25 yds with irons from the Beretta Centurion 4.25 in. I didn’t measure groups from the RDS-equipped AP5P but they were considerably tighter.
