Yes in my experience it is top notch ammo.
I have shot IMI Samson ammo in 9mm, 45 ACP, 223 and 308.
Their 223 63gr ammo is some of the most accurate 223 ammo I have fired, as is their 150gr 308. I have killed deer with both of them and the bullets performed great as well.
Actually I have even killed a deer with their 185gr Hardball 45 ACP.
The 9mm ammo was marked under the UZI brand as Carbine Black Tip.
The 45ACP ammo was marketed under the UZI brand, as High Velocity 185gr Match F.M.J. S.W.C. HARDBALL.
It was actually a round nosed bullet, with a wad cutter shoulder behind the round nose. It has always fed 100%.
It is some of my favorite 185gr 45 ACP ammo ever. I am wearing a magazine of it now...
Also before I retired, when 5.56 ammo was near impossible to get, my Dept got a bunch of 5.56 ammo in Winchester white boxes marked "Made in Isreal"... It was packed loose in the white box no internal brown packaging seperating the individual rounds. It shot great.
