Has anyone tried 60-95 grain bullets in 9mm Luger from carbines? What kind of accuracy, external and terminal ballistics should I expect?
Has anyone shot 22TCM into gelatin from a rifle? Photos?
I should have a chance to test these eventually, but would be curious as to the experiences of others.
TCM into clear gel – use earphones, the audio is a bit low.

As far as I know .22,.357 & .44 magnum cartridges gain at least 50% velocity in a 16 inch barrel. I shot bowling pins with 158 grain .357’s with a 6″ Ruger Blackhawk & a 16″ Marlin carbine. Assuming I did my part the pistol knocked the pins down with enough force to roll them off;the carbine BLEW the pins off the table.
I’ve shot 95gr 9mm’s out of a Glock & was not impressed with the accuracy.
Very light round nose and hollow point pistol bullets from a carbine, tend to act very much like round balls in that they bleed velocity rapidly. Long bearing surface heavy bullets tend to give better range and better accuracy AT range, and deliver more kinetic energy than light bullets. Light pistol cal. bullets are better for low velocity target shooting and small game.
Most of my manuals are at home, but in Speer #12 the lightest 9 mm bullet they list is a 100 grain JHP with a BC of .111, topping out at 1296 fps from a 4″ bbl auto pistol using 8.2 gr Blue Dot. No data on carbines in that caliber in this book. I’ll check more when I get home. A good estimate would be that that bullet in a 9 mm carbine would be ballistically similar to the 7.62 x 25 from a service pistol, but would not come close to achieving the traumatic shock threshhold of ~2000 fps impact velovity.
Then there’s Liberty — 50 grain, description says 2000 fps in pistol applications. Would be interesting to try that one with a chronograph. Or a gel target.
Ballistics by the Inch has data for 90 gr. Corbon – 1740 FPS from a 16 inch bbl.

Sierra shows their 90 grain JHP (stock #8100) maxing put at 1650 from a 16.5″ bbl using either Unique or Blue Dot. They claim best accuracy potential with 8.7 gr BD for a V of 1600 from the same bbl.
Plug those numbers into Joe’s Modern Ballistics and you’ll have the trajectories. BCs are looking to run around .104 to .111ish in that weight range. Not a whole lot better than round ball, as has been pointed out. In light of that you’ll need a compelling reason to want light 9 mm para carbine loads as opposed to 12 gauge buck.
