    38 Special Expansion/Penetration Testing

    KBintheSLC: The reason I asked my question about the weight of the recovered LWC bullets is because, if they are cast of hard alloy, they probably weigh substantially less than the nominal weight. Brassfetcher (who posts on this forum as JE223), in his test of this load, weighed two of the...

    Ballistic gelatin test results : Buffalo Bore 150gr hard cast wadcutter

    JE223- Did you weigh the recovered bullets? The reason I ask: The BB bullet seems to be a typical double-ended LWC, and these usually weigh about 147 grains when cast of hard lead alloy (BHN about 20). Thanks in advance. Pete

    Ring hammers: Is there a practical reason for 'em?

    Archie: The yahoo yanking on the hammer is you, the shooter. In the old days, i.e., my youth, most handgun shooting was one-handed, just as NRA bullseye competetion still is. The shooter's off hand would be used to pull the cord and recock the hammer. Pete

    Ring hammers: Is there a practical reason for 'em?

    It is my understanding that one of the original purposes of the ring hammer was to facilitate dry-fire practice. By attaching a piece of cord to the ring hammer, it can be cocked and recocked with the off hand while the strong hand remains in firing position on the grip. Another reported...

    Forensic evidence info

    Oleg: To anyone interested in forensic science, I recommend Larry Sturdivan's book THE JFK MYTHS (Paragon House, 2005). This is the most rigorous and scientifically sound examination of all the physical evidence from the Kennedy assassination that I am aware of. Pete

    pachmayr grip adapter sizes

    I also would like to know what revolver the Pachmayr #5 grip adapter fits. (I have a #5L in excellent condition.) My catalogs as far back as the early 1970's do not show this model number. Pete

    What IS a "full power" .357 magnum load?

    We also need to avoid comparing apples and oranges. The published muzzle velocities of the .357 (and other revolver cartridges) before the late 70's were obtained in long pressure barrels without a barrel-cylinder gap. About 1977 or so, SAAMI specified a new pressure-test-barrel configuration...

    Cylinder Throat Size vs Bore Size

    Jim Keenan - Jacketed bullets for the .38 Special are usually 0.357", and hard cast bullets run 0.357" or 0.358". Would you be concerned about the increase in chamber pressure involved in "dynamically resizing" these hard bullets to 0.355" in the chamber throats? In the case of hard cast...

    Cylinder Throat Size vs Bore Size

    Most of the recent discussion on this topic concerns the undersized throats in .45 Colt revolvers. There is a much more common problem with undersized cylinder throats in S&W J-frame .38 Special revolvers. Apparently, there are hundreds of thousands of J-frames out there with nominal 0.3555"...

    Size codes for George Lawrence holsters?

    Old Fuff and C. R. Sam: Thanks for the reminder about the old catalogs. I threw away my old Herter's catalogs about thirty years ago, but I found my original copy of the 1961 Stoeger's Shooters Bible (No. 52). On page 350 is a list of the Lawrence size codes. Thanks again. Pete

    Size codes for George Lawrence holsters?

    The George Lawrence Company, while it was in business in Portland, OR, stamped two numbers on the back of its holsters. The first was the model number; for example, the Model 34 was the FBI-style sheath. The second number was the size code; for example, size 528 fit a 6-inch S&W K22 or K38...

    Bill Jordan's Homemade Wax Practice Bullets

    I tried the wax bullet bit forty years ago with a .357 Ruger Blackhawk. Works fine as long as you drill out the flash holes in the cases. Of course, the wax bullets hit far below point of aim, but the biggest problem is the bore fouling . . . a nasty heavy residue of wax and primer debris...

    .401 Magnum?

    Ah, the memories of the Herter's catalog! Everything was the "Model Perfect". In the early 60's, I bought a lot of stuff from them and it was always excellent for the price. I'm pretty sure their brass was made by Norma, initially at least. I bought a few hundred of their .357 Mag cases and...

    Walther P1/P38 trigger pull wieght?

    In his Trigger Pull Data Search software (Version 2.1), Scott Doyle has results for 4 samples of the P38 and for one sample of the P38K. For the P38, the SA pull varied from 4.0 to 6.8 lb, with an average of 5.5 lb; the DA pull varied from 8.3 to 14.8 lb, with an average of 12.0 lb. The one...
