így érdekelne a teljesítménye, ballisztikai görbéje,
Nem túl sok infó, de kis gúglizás után ezt találtam 357 mag lőszer revolverből és puskából történő kilövésének összehasonlítása ügyében:
- With 125-grain handloads, the revolver averaged an even 1300 feet per second and 469 pound-feet of energy, while the carbine delivered 1937 fps and 1041 lb-ft. That’s a 49 percent velocity increase and a 122 percent increase in energy from the same cartridge. Yowza.
- With Remington 125-grain JHPs, the revolver got 1442 fps and 537 lb-ft. The carbine got 2038 fps (!) and 1153 lb-ft, for a 41 percent velocity gain and 98 percent boost in energy.
- Shooting the 158-grain .38 Specials, the revolver clocked a leisurely 676 fps and 160 lb-ft. The carbine achieved 944 fps and 313 lb-ft, a 40 percent increase in velocity and a 96 percent increase in energy.
- The S&B 158-grain JSPs gave carbine numbers of 1451 fps and 739 lb-ft, but the chrono battery died before we could measure them from the revolver.
- My mild 158-grain lead SWC handloads produced 1176 fps and 485 lb-ft from the carbine, which was better than I’d expected since they only burn a small charge of Unique, a fast-burning pistol powder. I couldn’t measure their velocity from the revolver, because they’re so smoky and sooty that the flying particles gave false readings from the chronograph. An old Speer reloading handbook interpolates them at about 980 fps from a pistol, which would give the carbine about a 20 percent velocity gain and a 44 percent energy gain.
Vagyis a revolverhez képest a puskából lőtt lőszer sebessége 20-44 %-kal nő, míg az energia 40-120 %-kal. Legalábbis a fenti esetekben.
