1700+ out of a .40? OMG.
put it in a carbine, then maybe. Anyone make a 10mm lever gun?
12gr longshot over a 135gr is a fairly well known "nuclear"40 load, the powder is incredible, you run out of room before you get over pressure, have hit stupid velocities in 10, 38super and 460 Rowland with it. Lots of people turn their nose up at 40, but you can load it from 300-600FPE from standard 9mm power all the way to match moderate 10mm loads, not much else can do that in an auto.
And I thought 12gr of blue dot under a nosler 135 was snappy!
I try to tell ppl that 40 is the best round if you reload due to this. It's super versatile. You won't get it as soft shooting as IDPA minimum 9mm guns but it has a huge weight and speed range.
Was your 10mm AR a blowback action?
I'd like to do a 10mm AR or a 357 SIG but a DI.
So hold on, could you guys see the picture in the original post all this time? I just changed it.
10mm levergun ? Sure ! It's called .38-40 , in a modern M92 clone.
Since I have some free time at work, I checked the loads for 40 versus 10. Longshot isn't even mentioned in the 10mm section, and it's actually slower than the 40 load. ???
Which book? Hornady is showing Longshot for 180 and 200 grain pills in the 10mm data
