Too stout of a load?

[788Ham]

I've got some .357 ctgs I loaded back in '90 and '93.

'90 loading: 125 gr. Horn. XTP
CCI550 primer
20.0 gr. 4227
This load, in the Hornady 3rd Edition, shows that load @ 1400 fps.
In the 7th Edition, for the same bullet weight and powder, 17.5 gr. is still in the safe load, 18.7 is in the red.

'93 load: 125 gr. Horn. XTP
CCI 550 primer
19.0 gr. H110
This load in the 3rd edition, shows approx. 1375 fps., 20.8 is in the red.
This load in the 7th edition shows 19.4 gr of H110 @ 1450

Now, my question is, are these loads too stout to fire in my SP 101 3" revolver, without causing havoc and possibly shooting the revo. loose? I've looked online on Midway, checking the ammo they have listed for sale, checking each load for specific fps listed. My reload books show the firearm used to test this load was a Colt Python 6" revolver.

Thanks, hope no flaming !! LOL

Here is some published data. I think your IMR loading looks a bit heavy at 20 grains since This data shows 19.5 as being compressed. Your H-110 loads look OK to me.
Never the less, I would use caution and look for signs of pressure as you work up to max.

I load exclusively with H110 for my .357 mag. loads. I use 22-24 grs for 110 gr. jacketed, 125 gr. jacketed I run 20-22 grs., 158 gr. jacketed 16.5-18.0 grs. In my opinion, the H110 loads are in the safe zone for that Ruger.

Stack,
I certainly appreciate your time, knowledge and typing this out. I realize some reload books will stay the same, edition to edition, but when I looked at the reloaded ammo earlier this evening, something just didn't jive. The older book didn't look that far out of line, the 4227 load, but then I looked at the newer reload book, THATS when the bell rang! I'll just pull the bullets and start over, no big deal, lesson learned.

Another question: Have you ever used any of the Speer "Deep Curl" 158 gr. .357 dia. bullets? A friend of mine told me about this bullet in .44 {.429 dia. } that he reloaded, said they were extremely accurate. I tried to get some from Midway about 6 - 7 months ago, they were out, but could be back ordered, which I did. Just this past week they got some in, and I got a box of them, a "Wicked" looking bullet. I guess I'll unload these others and try the DC bullets.

Thanks for your help and time, I truly appreciate it!

Jim

If you have powder from that era the book was published it should be fine. Mfg tweek their formulas to improve on them and there is slight changes in batches. Soon as I buy new powder I use the newer published data. Which some times is real conservative due to all the liability. So with new powder decades apart rework your loads.

No I haven't. I only load 140 gr XTP's and 158 gr Noslers at present.

Speer's Deep Curl handgun bullets are essentially the old Gold Dots, and if you call Speer, that's what they'll tell you. They are a plated/bonded lead core bullet of good reputation.

The current load data on the Hodgdon site lists the same charge of 20.0gr H4227 under a 125gr XTP bullet you loaded back in 1990 so I would say it's still safe...

Hodgdon is listing a charge range of 21.0gr to 22.0gr H110 under a 125gr XTP bullet so your load of 19.0gr is light according to Hodgdon.

Like said above, Speer Deep Curl bullets are Gold Dot bullets and I agree, they are accurate bullets. I don't buy them because the price is too high and they are very hard to find. I use Nosler or Hornady XTP bullets instead. I really the Nosler bullets and they are sold in 250 piece bulk packs for a good price.
