Chronograph: recently acquired Garmin Xero. (I'm digging it.) Figures rounded to the nearest decimal.

16-inch Ruger AR-556, 5.56x45, 55-grain FMJ (aka M193): average 2,960 f/s for 10 shots. Didn't keep track of the brand. I'd expect them to perform about the same.

16-inch S&W M&P15-22, 40-grain HV solid: average 1,158 f/s for 10 shots. Again, didn't keep track of the brand.

3.1-inch P365, IMI 9mm Luger, 115-grain JHP: average 1,106 f/s for 11 shots. (This surprised me a little.) This time using the "muzzle 'smash'" calculator, average for this was 313 ft. lb.

2.7-inch Ruger LCP Max, WWB .380 ACP, 95-grain FMJ-FP: average 852 f/s for 5 shots. Average "muzzle 'geewhiz'" was 145 ft. lb. The real kinetic energy would be slightly higher, but not much, as I entered 90 grains.

What were you anticipating? Too high; too low?

I was expecting that it would be lower, around 1000-1050 f/s, coming from such a short barrel (only ~2¼ inches of actual rifling) and not being marketed as a "short barrel" or "+P" load. It will be interesting to see how some other loads perform as I work with the chrono more. I have some Sig-branded and marketed specifically for the 365.

Here are some more results from today's range trip.

M&P15-22, Winchester Super-X Power Point 40-grain HP, advertised 1,280 f/s, averaged 1,273 f/s for 10 shots.

Same load, 20-inch Springfield Armory 2020 Rimfire (Turkish-made bolt-action), averaged 1,284 f/s for 10 shots.

Also in the Springfield, Aguila Super Extra, 40-grain solid, advertised 1,255 f/s, did 1,219 for 10 shots.

Ruger AR-556, "Monarch" (Academy house brand, variously made in Brazil, Serbia or Turkey) 5.56 M193: 10 shots averaged 3,085 f/s, 1,162 ft. lbs., 20.0 SD. Another load* did 3,016 f/s, 1,111 ft. lbs., 26.6 SD.

M&P15-22, CCI Mini-Mag 40-grain solid, advertised 1,230 f/s: 10 shots 1,232 f/s.

4.5-inch Ruger Mk IV, Winchester Super-X 40-grain solid, advertised 1,330 f/s from a rifle: 9 shots 1,080 f/s.

P365, Sig-branded/advertised as being short barrel optimized, 115-grain JHP: 1,075 fps, 295 ft. lbs. for 4 shots.**

P365, Winchester "Defense" 115-grain JHP, advertised 1,145 f/s (probably from a longer barrel): 10 shots 1,025 f/s, 268 ft. lb.

The above two are actually about what I'd have expected out of the 365's short barrel, but are still somewhat inferior to the IMI (which also has an aggressive, serrated HP) in the first post. If available I might look into obtaining some more.

* Most likely WWB. I loaded the magazine weeks, possibly months, ago, before getting the chrono. WWB is advertised as 3,180 f/s, but probably out of a longer barrel.

** All I had left.

The advantage of having a way of determining the facts rather than relying one someone’s claims:

Thanks for the rest of the report.

Today's session:

22-inch Browning AB3
Cartridge: 6.5 Creedmoor
Norma "Whitetail" 140-grain flat base soft point
Advertised velocity: 810 m/s (2,657 f/s)
10 shots
Average: 2,597 f/s
Energy: 2,094 ft lb. (advertised 2987 joules or 2203 ft.lb.)
SD: 16.4

Same rifle with Sellier & Bellot "Tactical Ammunition" 140-grain FMJ-BT
Advertised velocity: 2,657 f/s
10 shots
Average: 2,690 f/s
Energy: 2,249 ft lb. (advertised 2,094)
SD: 18.8

20-inch Howa 1500 Mini-Action*
Cartridge: 7.62x39
Fiocchi Range Dynamics 123-grain FMJ
Advertised velocity: 2,375 f/s
10 shots
Average: 2,375 f/s
Energy: 1,540 ft lb.
SD: 27.7 (No such thing as "match-grade" in this cartridge.)

* This is a neat little rifle for short/medium range hunting (if I were a hunter). Its action length is proportionate to the length of the cartridges it's chambered for (.223, 7.62x39, 6mm ARC, 6.5 Grendel). It's also threaded for a suppressor, and you can get 255- and 182-grain subsonic from Hornady and PPU, respectively. Perhaps some day.

Browning AB3
Cartridge: 6.5 Creedmoor, PPU (Serbian-made Prvi Partisan) Supreme Line, 140-grain Sierra Match King
Advertised MV/KE not specified (could find nothing on the box)
Average for 10 shots: 2,613 f/s, 2,123 ft. lbs., 13.2 SD.

3.7-inch* Sig P320 compact
Cartridge: Monarch 9mm NATO (so marked on the box, Turkish-made), 124-grain FMJ
Advertised velocity: not specified
Average for 10 shots: 1,120 f/s, 346 ft. lbs.

Same cartridge in the P365, average for 9 shots 1,070 f/s, 316 ft. lbs.

P365
Cartridge: Federal "Train & Protect", 115-grain JHP. Outwardly identical to the famous 9BP.
Advertised muzzle velocity/energy: 1,180 f/s, 356 ft. lbs., most likely taken from a longer barrel, if not exaggerated entirely.
Average for 8 shots: 1,085 f/s, 300 ft.lbs.

Will be testing the Train & Protect with the longer P320, as well as Winchester Q4318 9mm NATO. The latter load is advertised 1200 MV/396 KE.

* Shown as 3.9" per website specs, but only if the little "hood" extension thingy is counted. From the actual chamber to muzzle is 3.7.

What is the Browning’s barrel length?

I got an average of 1218 fps for the real BPLE from a P365 several years ago.

My test of the Winchester Q4318 from a full size P320 gave an average velocity of 1190 fps the last time I checked it.

22 inches on the Browning. (It was mentioned earlier.)

I can't tell (feel) any substantial difference in recoil between the slower and faster 9mm that I tested.

Thanks; I didn’t think to check back about the barrel length.

A few weeks ago I set up my chronograph checking some 32 H&R mag loads. My casual loads are 78 grain coated lead with older IMR 4756 I’m using up.

I stayed inside of book data but with a modest pressure round, modern gun, I don’t mind being at the upper end. Still no powerhouse, I realize.

I still have a chrony I have to shoot through the uprights. Should it fail, I’ll get the modern type, much easier.

The Q4318 went 1,087 f/s with a KE of 325 ft.lb. from the P365. From the P320, 1,135/355.

From the P320, 1,141 and 333. Interesting that this "old-school" load is hotter out of both guns than the supposedly more modern (straighter-sided and wider-mouthed HP) Winchester. It would be good for guns that are fussier with modern wide-mouthed HPs, and less expensive ... if Federal still carried it. (This load shows "currently not available" on the website, and the 9BP not at all. I bought it circa 2022.)
