View Full Version : Chrono'd 357Sig in G35?
Anyone have this? I'm running 125's, Win Ranger & Gold Dots. Accuracy is fantastic, & I don't have a chrono....
I'd like to know as well.
average for win ranger 125 bonded jhp and ranger-t jhp out of our issued Glock 31s is around 1380fps.
with a longer barrel, i'm sure it'll pass 1400 easily.
You have to remember though, an aftermarket barrel in the G35 isn't going to have polygonal rifling.
And that polygonal rifling in Glock stock barrels create a tighter gas seal, and give slightly better velocity per inch than traditional rifling.
I'd be willing to bet money that the velocity wouldn't be significantly different between a G31's 4.49" barrel and an aftermarket 5.32" barrel in the G35.
Yet another reason Glock needs to make a factory longslide .357! Hello 1600's!!!
Here's what I have crono'd in a G35 with standard LW barrel:
Speer Gold Dot (54234): 1438
Federal HST 125gr: 1415
Win White Box 125gr: 1438
Hornady 147gr XTP: 1275
Corbon 125 match: 1468
Can't find my data on 125gr winchester ranger but was similar to Gold Dot if I recall.
Several years ago I chronoed some Pro Load 357 SIG (no longer available) ammo from my Glock 35 with KKM barrel. It averaged 1570 fps over my Pro Chrono. The same ammo, which was loaded with Speer 125 gr Gold Dot bullets, went about 1500 fps from a KKM 4.4" barrel, and 1395 fps from a Fire Dragon 3.5" barrel.
So it seems to me that full power 357 SIG ammo benefits greatly from longer barrels. I did not have a 357 SIG barrel when I owned a 24, but I would have liked to chronograph some ammo from a 6" or 6.5" barrel just to see what it would do.
