GP100: Bradshaw

Gibson.... Thanks for the dope on WC 820. But "15.25 grains?" How do you measure powder to 1/100 grain?!!! Man, you got to be the PUMPIN IRON SCIENTIST.

A few notes on .41 frame double actions (Colt Python, S&W M586/686, GP 100):

* After sending a Model 19 back to S&W three times, the test lab at Speer in Lewiston, Idaho replaced it with a Security-Six. Thirty thousand rounds later, the Ruger had not broken down. I would expect severe forcing cone erosion. (Why any ammo lab would use an M-19 for testing .357 mag ammo is a mystery only only a sadist could explain.)

* To test a Security-Six, Ruger screwed in a barrel, which they neglected to drill & rifle. A .357 Magnum fired into the solid barrel departed the cylinder/barrel gap in terrific sideblast. Otherwise, didn't do the gun diddly. I didn't see it; was told so from the very top.

I may be wrong, but the "barrel stub" poking through the barrel socket into the .41 frame does not permit the thick ring of steel around the forcing cone of a .44 frame. It should be better than on a .38 frame, but this isn't always true.

In silhouette, a Python in the hands of Jerry Moran of Michigan, Allen Kirschner of South Carolina, Philip Braux of Louisiana, and others, established in no uncertain terms the credentials of that revolver. Eventually, guns with a thin barrel throat may crack the barrel through the forcing cone most often at 6 o'clock. (Jerry Moran loaded the Sierra .357 170 FMJ over 296; don't know what others loaded. Moran was not a Rocks & Dynamite silhouetter. He's one of the great Python mechanics and did his steel shooting with a blue 6" Python.)

I don't know much about the GP 100, other than rugged design. I would guess that its first place of wear-through might be the barrel throat. If you recover bullets fired into snow this winter, you'll have an link in the puzzle of how your bullet responds to that powder/pressure, and whether your bullet made a pristine leap from chamber to rifling.

All the best,
David Bradshaw

Shoot it out of an LCR...


that does not sound like fun to me,reminds me of the titanium s&w revolvers,to each his own i guess.

I had one of the titanium S&W 329's and the recoil is nothing to write home about. I was actually disappointed in the recoil as I bought that $1K toy based on all the horror stories about recoil.

I suppose my loads were right considering they were 300gr Cast HP's at 1300fps.

Now, I am not sure the LCR would survive the loads for long, but the shooter should be no worse for wear.
 
There have been only two guns that have left a bruise in the middle of my palm and made me want to stop what I was shooting and do something else. The 500 JRH with a Hogue monogrip and no gloves (two shots and I stopped to swap the grip out, it HURT), and an LCR firing my own 158 gr. full power handloads. Shot two cylinders out of the LCR and had a bruised hand for a week. I don't have much padding on my hands, so you guys may be fine.

TEK4260 is my son and he likes recoil. I got a 480 ruger from him. It had thin wood fingergroove grips on it. I shot it 6 times and came home and put the factory grips back on it with the rubber and wood inserts. I got to checking and found that the alaskan grips would fit it with the zorbathane in the back. I ordered these grips and put them on the gun before I shot it again. They helped but the gun is still a handfull to shoot. I had it cut down to alaskan size and it still runs high on the recoil scale even with the short barrel and the alaskan grips. It's not one you would take out and run a box of shells through in a day.
