I got some 244 to try because it looks good on paper, and it is indeed cheap. 3.8gr 244 / BBI 125gr (conical) @ 1.142" / Tula SP tested in a Glock 34 mean = 1055.7 SD = 11.8 min = 1034.1 / max = 1074.3 N = 20 Didn't rigorously test accuracy but it seemed better than my usual N310 loads.

The only powder that beats N320 is N310 (probably not for 115s though).

The 17 is a 126mm, the 20 is a 140mm, and the 26 is a 170mm. More or less. I just got a Prodigy and haven't shot it yet, but I did check some of my collection of STI and SV mags in it. Everything fits and locks in, but some don't drop free. I think the mag catch will need some work.

Silhouette is not all that different from True Blue. I was always puzzled why they kept both powders in their lineup given how similarly they perform. Like Joe, I'd recommend HS6.

I came back after 9 years away. It was like riding a bike. People are using different gear but the game is the same.

Seems like they should work, 38 LC is only 0.125" shorter. But, I do see that Lee has different sizer SKUs: 357 Mag: 90530 38 Special: 90964 38 Long Colt: 91207 38 Short Colt: 91207 I just happen to know where Lee keeps these, but you can probably find it for Dillon too...

Power Pistol will work but it will be unpleasant. Longshot will be similar. Since you're not going for Major, you might want a slow-but-not-slow-enough-for-major powder, like N340 or Win 572. Or BE-86, Unique, Herco, but Alliant powders are so expensive now... HS6 is great but it will not burn completely at book loads, same for Ramshot Silhouette (and probably also True Blue).

Is the grip angle different? My eyes can't tell. I've been wondering this since I first saw these, and tried to wrap my brain around how a Glock mag would fit into a 1911-esque gun.

I've been shooting 135s (132 actual) and chrono'd some 145s (145 actual) yesterday. Not a huge difference on paper: 13 grains heavier bullet, 2 tenths less powder, but they felt significantly softer to me. No perception of "sluggishness". I'm going to make another thread later with all my data and some fun graphs, but the winner is 3.0gr N310 + 145gr Summers Enterprises at 1.160". I may keep shooting the 135s anyway for other reasons but this is a truly nice load. (I bet it would be whisper-quiet with a suppressor!)

34 slide is the same weight as the 17 slide, that's what the cutout is for. If you think the slide moves slower it's an illusion / confirmation bias. 34's longer barrel gives you more velocity, worth 1 or 2 tenths of a grain of a fast powder. I suppose it's worth nothing if you shoot factory. I would get a 34 mostly because I've had one for 20 years and am very accustomed to it, and I see no advantages to a 17 other than 50-ish bucks of sticker price.

Probably the only time you'll see a Pepper Popper depicted in a Hollywood movie... I'm not much of a review writer but I will say I enjoyed it. It reminds me of Drive (2011) in some ways.

The most general answer is "find out what you prefer and shoot that". My answer is closer to Guy's above: heavier bullets mean less powder, less blast, less perception of recoil. I think if you try 135s or 147s you'll like them.

I exported some data the other day, using the Android app -> Google Drive, and the files do contain the session names, just not in a convenient way. Here's a sample "CSV" file in its entirety. It's not remotely a standards-compliant CSV file. The first row has the session name, second row has headers (there's a weird unicode character right before "#" that may not appear), then data, then extra stuff at the bottom. What it definitely doesn't do is put the session name in the file name which is what I'd prefer. By default it names every file "Exported CSV" or something useless like that. Tedious.

I'm at 3+ uses of my major brass. And I don't mean "load it major once then put it in the minor pile" I mean three major loadings. It's fine!

From memory, 4.5gr N320 with a coated 180 (BBI), or 5.0gr with jacketed (MG), both loaded long. I did once upon a time load major 40 with N310. Experienced a few pierced primers and gave up on it. Pretty sure I was having setback problems... I might be willing to try it again.
