Had a pretty rough day of shooting.
Drove out to my shooting spot. Set up target at 25 yards. Set up Labradar. Take my first 20 shot group and it started raining, hard.
Pushed my crap into the pickup bed, shut her up and piled into my truck to wait it out.
My brass was still getting mangled up like my first outing and failing to eject properly.
So while I waited out the rain I took my gun apart and retightened the extractor a bit.
Rain finally stopped after about 30 minutes. Jumped out and loaded up my XDs 45. I didn’t want to set the tripod and Chrono up with more rain as a threat. Popped off 100 rounds of 45 acp ball ammo with a 230 gr FMJ over 6.3 gr of Unique. Pretty much confirmed, I’m done with that gun. I always liked it before, but now that I have a Sig P938 Legion, and enjoy shooting that gun so much more, the XDs seems clunky, unrefined, and pretty unnecessarily punishing. Probably going to ditch it.
Then the sun came out. So I set up the Chrono again. Shot a bunch of fast groups to get the data I wanted. DW is still mangling brass but seemed a little more consistent. So I’ll tighten the extractor a tad more and see.
Cracked off some 357 H110 max loads. Disappointed at the velocity. I didn’t even get up to 1200 FPS consistently. Sure made some big flashes.
Anyway, 38 Sup data is below. Velocity is only creeping up.
Temp was 62 degrees, humidity 60%, elevation 6600 ft. All velocities are at the muzzle.

Those cases were loaded to 10.3 gr. Looks like a slight cratering on the primer, but edges are still round. So I think I’m going to try 10.4., and then leave it at that.
All three loads were accurate and pretty soft shooting. Didn’t feel like I was beating the gun up. So at least I have some nice accurate fast loads. Chances of getting to 1425 FPS seem pretty much nill, but if they shoot, it’s not like 1400 FPS is bad.
4 hours of dodging rain to get 6 sets of data. Maybe shot 250 rounds.
I’m thinking my XDs and E Series S&W1911 are going to get traded toward a Dan Wesson 45 bobtail.
