I loaded some 125gr XTPs in once fired Remington 357 brass over 21.0grs of W296, cci 550 MSPP
All loaded in same session, weighed every 10th charge out of 50 rounds
3” 686. Velocity Avg 1382 ES 157 /SD 41
8 3/8” 686 Velocity Avg 1676 ES 158 /SD 47
All cases extracted normally, primers looked good etc.
Load was a piece of cake in the 8” gun, big fire in the 3” haha.
Is that ES/SD acceptable?
I didn’t shoot any for accuracy yet.

In my experience W296/H110 excels more with heavy for caliber bullets and pretty much require magnum primers for consistent ignition. That said SD results in the mid 40s is better than I was expecting you to get as you set everything up. If they shoot well on targets they should be fine, or Id go with something along the lines of Long Shot, Power Pistol, Blue Dot, a mid range burn rate pistol powder.
YMMV

I’m gonna try some 158gr loads next, thanks for the reply. I figured the 125gr bullets might be light for that powder I had read that.

I shoot 16 grains behind a 158gr jacketed bullet. That’s over book max some places and under in others. I’ll have to check the chrono data but it’s my go to load for testing how a gun will shoot

The lightest bullet I load in the 357 is 158 grains but typically I go to 170-180 grain bullets. For me, H110 and a magnum primer will get sd's half of what you were seeing. Again, I use heavier bullets, either a Federal SPM or the 550 you were using, and a stout crimp.
Like Fowler stated, if I were to shoot lighter bullets in the 357, I'd go to a faster powder than the H110 burning rate powders.

Is that ES/SD acceptable? I didn’t shoot any for accuracy yet. ***** The old Hornady 125 JHP (predecessor of the XTP design), over 18.3 grains of the old Hercules 2400, in .357 Mag brass with CCI 550 mag primer, milked the accuracy of this excellent bullet well beyond 100 yards. That was years before the 20th turned to the 21 century. I consider the load hot for K-frame S&W Model 19’s and 66’s. memory says I plucked this load from an early Hornady manual. Extreme spreads run much tighter than you record with slower Winchester 296. 300 fps spread between 3” and 8-3/8” barrel S&W’s indicate 296 is too slow for the light HOLDBACK offered by 125 grain projectile. As Fowler and others warn. While ES does not correlate to accuracy, directly, 160 fps ES is way out of line. Win 296 (and H110, which is 296 relabeled by Hodgdon) produces efficiency with accuracy with good 158, 160, 170, 180, and 200 grain bullets. David Bradshaw |

I’ll have to check the chrono data but it’s my go to load for testing how a gun will shoot I started loading some of the 158gr XTPs today. Made some with 15.0 /15.5 /16.0. Hodgdon says 16.7 is max. |

For deer, personally I would use the 180s.
I used to load BlueDot with 125 jhp a few decades ago, I got great velocity, if I remember right it was somewhere around 1550 from a 4" GP100, the muzzle flash was greatly reduced and it gave excellent accuracy. I've heard that now there's a warning about not using Bluedot with the 125s. 2400 should be a great powder for the 158s. It might be interesting to shoot a 296 load next to 2400 near dusk to compare the muzzle blast.
I just remembered about Accurate no11FS. The fs stands for flash suppressed. Burn rate is supposed to be close to 296. It may be worth a try also.

That's more like it! There's something about a heavier bullet in a 357.
As to shooting the 2400 loads and H110 loads at dusk for comparison, the H110 will win every time! Who needs night vision anyway?
