9mm chrono data

Hey 9mm fans I did some chrono testing today with my Beretta 92 FS. Below are the average velocities and bullet expansion in water where applicable. Expansion testing was done on one bullet for each load, as I don’t have that many water jugs. Temperature was 50 degrees.


1. Federal +p+ 124-grain Hydra shocks averaged 1174 for 4 shots. The bullet fragmented into one large piece and one small piece. The bullet core expanded to .705 inch. The jacket also separated but this is normal in water. The largest piece weighed 81 grains. This bullet stopped in the 4 jugs, as did all loads tested except one. The maximum spread on this round was 29fps.

2. Remington’s +p 124-grain saber averaged 1132 for 3 shots. The bullet had 100 % weight retention and expanded to .65 inch. This bullet also stopped in the 4-milk jug. Also the maximum velocity spread on this round was 37 fps.

3. Speers standard pressure 124-grain golddot. This one averaged 1019 for 3 shots and had a 47 fps spread. The bullet expansion was disappointing at .494 inch. This load also went into the 5th jug. This load had 100% weight retention. The +p version of the load should be a lot better. I had none available in my ammo storage.

4. PMC starfire 124-grain bullet was not tested for expansion as I ran out of jugs but here are the velocity figures. This load averaged 1088 for 3 shots and had a 28 fps spread.

5. I also tested Federals standard pressure 124-grain hydra shocks for velocity. The average velocity was 1111 for 3 shots and this load had a 73 fps extreme spread.

6. For comparison I tested federals 357-sig 125-grain jhp in my glock 31. This load averaged 1430 and expanded to .65 inch. This load had 100% weight retention.

7. I also tested some 38 special loads in my back up 37 smith airweight. Federals Nyclad 125 grain load averaged 860 and only deformed on the nose a little and did not expand past its original caliber of .357. This load stopped in the 5th jug.

8. I also tested Remington’s +p 125 grain 38 load and it averaged 830 and it went through my last 6 jugs and was not recovered.

That’s it for today maybe in a little while I will do some 40 chrono testing.

I intend to go into harms way.
 
Hello and thanks for the information. (Don't be concerned about the Nyclad .38's lack of expansion in water. The water cannot get under or between any jacket and the lead bullet which is one reason water expands many bullets to fragmentation when they don't do so in gelatin or tissue.) Best and good luck.
