38 Special Gold Dot Chronographs: 135-gr. HP
FYI Only:
Read a nice public article today in the Guns and Ammo magazine (on page 14) where Payton Miller performed some testing of Speer's new 135-gr. Gold Dot HP.
A summary of the "Chronograph Results" is as follows:
* 2" barrel testing compiled a 5-shot average of 878 fps with a high of 900 and low of 855, resulting in a max spread of 45 fps and a Standard Deviation of 16. Revolver used was a S&W Model 49 Bodyguard.
* 4" barrel testing compiled a 5-shot average of 976 fps with a high of 990 and low of 955, resulting in a max spread of 35 fps and a Standard Deviation of only 13. Speer advertizes "975 fps" from a 4" vented barrel. Revolver used was a S&W Model 15 and for accuracy, produced 5-shot averages of 1 1/2" at 25 yards.
* 6" barrel testing compiled a 5-shot average of 1,004 fps with a high of 1,028 and low of 977, resulting in a max spread of 101 fps and a Standard Deviation of 43. Recoil of the 135-gr. Gold Dot was likened to that of a 125-gr. +P 38 Special load and less than the slow & heavy 158-gr.
For comparison, the more massive 158-gr. Winchesters were chronographed for a 5-shot average of 760 fps (2" barrel), 850 fps (4" barrel), and 894 fps (6" barrel).
Black Hills' lighter grain 125's averaged 810, 911, and 926 fps respectively (2", 4" and 6" pipes).
The article sums things up by stating that "Speer's new 135-grain GDHP load is potent, controllable and accurate."

Hmmm...
I got 825 fps from a 2.75 in bbl Ruger Sec Six, and 950 fps from a 4.0 in bbl Ruger Service Six. They are pretty old guns though...

Looks like the new ammo in your ol' gun with the 4" pipe lost 26 fps due to blowin' out the cobwebs. :mrgreen: :thumbsup:
Thanks for the feedback!

Steve, one thing to consider, chrono results are very dependant on the individual firearm. I've seen a 4 inch M29 shoot faster (same load) than a six inch one. A Beretta M92 I had shot slower than a M19 Glock despite having a longer barrel. 
Ditto what Al said. Some years ago I was shooting a state IPSC match, and was informed that my loads had chronoed as minor (PF less than 175 in those days) from the test gun. In my gun, my 200 gr. handloads chronoed at 900fps, definitely major (PF 180.) I took my gun over to the chrono bench and let them shoot the loads through it. They made major. The test gun was a Colt GM, mine was a Springfield Defender (1987 model.)
