Out of certain barrel lengths. Ive shot a few that were not subsonic out of my PCC style firearm.So you saved your brass right?
9mm is easy as hell to load.
Pretty sure all 147g 9mm is subsonic.

With the Magnus or Magnus-S? I haven't weighed this one, but I can tell you that it's kind of a pig, for what it is. That chassis is not lightweight. LOL@FuhQ , How much does that sweet little pistol weigh as pictured??
It’s hefty, but it handles nicely (insert “that’s what she said” joke).Wow!! That’s crazy heavy for such a small rig!!
Love the look, bet it’s fun to shoot, too!
Would be nice and maneuverable in the deer stand.
Thanks for weighing it, much appreciated!!
Got her sighted-in, and did some groups with some slightly underpowered loads (about 993 FPS), and also with some factory Hornady Sub-X 190gr ammo (about 990 FPS).
I have some Hornady 190 Sub-X bullets that I will be loading up, and pushing closer to the 1075-1085 mark. But that will be down the road a little bit as I have 500 rounds of factory Sub-X to shoot.
Mind you, I have degrading eyesight in my right eye, and this was only a 10x LPVO, and the orange bull in first group is only 1”, and the orange bull in the 2nd group is about 1/2”… So, considering that, I think the groups turned out pretty decent given all the factors. And the fact it’s only a 8.3” barrel with a 7 twist, it’s pretty damn accurate. I’ll try to get some better groups tomorrow or next weekend with my precision subsonic handloads with Nosler 210 RDF’s being pushed closer to proper 1075-1085 FPS.
The groups are solid for subs, but I think I can get better out of it, as I had no problem running a quick dope chart and taking it straight to 300 yards. And 4/5 shots I’m hitting a full-size D28 at 300 yards, so it’s still pretty dangerous at distance. At 100-150 yards, if it was a deer, and I shot it in the vitals, it would be dead.
It shoots good, it runs smooth, no feeding hiccups with the MDT mags, and it’s ridiculously quiet with the full-size Magnus on there.

Before I started reloading, I tried such cartridges.I have 500 rounds of factory Sub-X to shoot.
Mostly people are satisfied with the first acceptable result and leave expensive experiments to those who hunt for paper targets.I guess not a lot of folks shooting (or experimenting) with subs these days...
G40 10mm (Alphawolf threaded barrel)
SNS 220gr. HI-TEK coated bullet
1.260" COAL
Titegroup
4.3gr. -> 940fps.
4.5gr. -> 972fps.
4.7gr. -> 994fps.
Blazer SP cases
Fiocchi SP primer
Sound wise, it's much quieter than subsonic 10mm 220gr. loads that use typical 10mm powders (Longshot, etc...). 4.3 Titegroup is into 9mm territory with my Fly 45. Not Titegroup 9mm load quiet, but just above a 147gr. bullet with 4.0 Autocomp / 4.2 CFE Pistol load (in a G34 with an AAC TiRant)
I havent really tried for best grouping but 1 inch at 50yards is dead critters in the yard lol11.8gr CFEBLK under a 220smk has been stupid accurate and stupid quite for me out of my 10.5" Rainier Ultramatch
Are you shooting from a bolt gun or semi ? If you’re using a bolt gun you need to explore the faster powders such as N105.100м
Hornady 208 ELDM
11.6 CFE
BTO 1.524

CFE BLK powder is too sensitive to temperature.
Shooting all year round, powder sensitivity introduces significant variables into the process.
Since the temperature difference is from (35 °C) 95 ℉ in the summer to (0 °C) 32 ℉ in the winter.
For example 11.4 CFE (the rest of the settings are the same)the difference in speed is 1080 -950 fps at the corresponding temperature difference
Maybe single base powder will solve this problem? If so, which one?
Swiss RS powder is available locally,almost the entire product line
Besides CFE I also have A1680 but it is almost the same.
CFE BLK is the only powder I found that produces plenty of gas to operate my 7.62x39 AR. I'm at 12.9-13.0gr using the 265gr Acme bullet. SD's in the high 7's using CCI #34 and a good crimp!11.8gr CFEBLK under a 220smk has been stupid accurate and stupid quite for me out of my 10.5" Rainier Ultramatch

VIHTAVUORI not very common in our stores, but I saw it on local forums, maybe I'll try it.
The question about single base powder concerned the generally known statement about the advantages of this type of powder in terms of temperature insensitivity.
Maybe someone has already had experience and this game is not worth the effort at all.
Of course, I understand that the caliber is not considered highly accurate for many reasons. Especially at the subsonic range.
Now take this load out to 1000 yards300м(328yd)

There were a few (3) hits below that would have ruined such a beautiful picture,
but I noted their lower speed on the chronograph (which is always online and prompts by voice) by 10-15ms.(32-50 fps)Therefore, I allowed myself to conditionally not take them into account here. (since the brass after resizing did not sort by neck tension).
And there were two misses on the gong during the DSF calibration in Kestrel.
So far I see that for this bullet under these conditions there is no need to calibrate DSF or calibrate velocity.
Apparently the G7 coefficient indicated by Hornady is averaged and coincides with the transonic range.
That is why the groups in the gong are a little higher, because it was during today's shooting that I realized that the calibration for the 208ELDM was unnecessary. We will see for other bullets later.
A little strange because for the 225 ELDM bullet there was such a need last season for a predicted headshot of a metal gong at 300m(328yd)

There was another test.
A comrade sold a bunch of LC fire formed brass, enough for my needs.
He selected by the top of SAAMI tolerances, for which he is grateful.
The same bullet was shot (all other parameters are the same), except for the case for comparison combustion, although one group is on the target in the middle below, the other is in the gong in the photo above.

My old S&B cartridges have a mileage of 6+ times, ES 13m/s(42fps) versus ES 26m/s(85 fps) in perfectly polished LCs. due to the carbon on the inner surface of the neck, which works as a lubricant. (this time it was without graphite, all cartridges)
LC annealed on AMP annealer/ S&B flame annealing
LC stainless steel wet tumble/S&B dry tumble corn cob
I wanted to make sure if it was worth ordering cartridges from this guy and compare his process with mine.
Overall, it was what I expected and I am satisfied with the purchase
The only thing is, its brass requires the neck to be lubricated with graphite for the first time. Since the ES /SD is twice as high as on my old ones.
In general, the group is better at gong than at 100m. Which is not an anomaly if you read enough of Brian Litz before bed.
For what?Now take this load out to 1000 yards
Because it’s funFor what?
I have for subsonic range of up to 380m available (according to the scope turrets) zero stop ring removed
