I am in the process of getting a Semi feed ramp in my SMG. But I was hoping in the interim that I might get better feeding with HP’s. Has anyone done this with any success? I know Barrelxchange says his will feed HP’s. Anyone Had any luck?
Has anyone throated an Uzi barrel for better feeding?

I prefer a semi-auto feed ramp; not so I can shoot hollowpoints, but for a little extra support for the chamber end of the barrel.
Ball ammo is what Uzis were designed to shoot-- along with everything else in my gun safe.

I sold an Uzi SMG years back that Vector put in a Semi feed ramp. It ate anything and everything I put in it. It’s a big plus putting Flat nosed subsonic ammo in it and shooting supressed. I am looking for that reliability again.
I think the semi feed ramp is the key. When fully chambered, .135" of the round already sticks out.
Any throating of the barrel would increase that unsupported case length. Feeds anything but ruptures cases, isn't a good trade-off.

I do it all the time to my barrels, Easy fix for hollow points
Could I send you a barrel to have that done to it? Or do you have a spare barrel to sell? Thanks

I used a dremel tool and a wooden jig to put a slight funnel on an SMG barrel
as I was about to do it, I said to myself, "You idiot, you are about to ruin a barrel."
it came out perfect. and I mean perfecto- it looked perfect, like it was done on a lathe and it works great
which is a miracle, because a dremel tool should never be within 10 miles of a firearm
anyway, US BARREL SHROUDS sells a barrel that will eat literally anything. It's actually a pretty good barrel, except that the chamber is a little on the huge side. no problems with it so far

You can make the end of the barrel slightly more funnel shaped without chewing into the straight walls of the chamber tha support the case
there is enough extra meat there
I used to have a sketch, I'll see if I can scrounge it up
did anyone ever have ruptured cases from throating a barrel?
Can't say Dirk... but I'm not foolish enough to say it could never happen.
From years of gunsmithing, I've seen guns damaged/blown up in some pretty creative ways... sometimes taking their owners/shooters with them.
Dropping the wrong size shotgun shell in then chambering the right size shell in on top of it.
A 20 ga shell can usually almost make it to the choke on a 12 ga. When fired, you end up with an almost cartoon banana peel where the muzzle used to be. Only without the laughing.
Hydraulic mouse in an M1911A1 barrel because someone oiled the bore then didn't bother to run a patch through it before shooting.
Makes disassembly "challenging".
Backstrap blown off along with entire top half of cylinder because some nitwit drilled out a 44 spl so they could shoot 44 mag through it.
Shooters figuring they could push a bullet lodged in the barrel out by just loading another round in behind it and pulling the trigger.
Honing out the chamber with a Dremel tool enough so that the cases swell to the point of turning a semi-auto into a single shot.
That one took an otherwise extremely nice M1941 Johnson out of commission.
Doing an internet images search for "firearms explosions" shows a number of weapons I'm glad I wasn't holding when they let go.
As sue-happy as people are these days, I don't feel like being the one defending myself in court because someone took a statement out of context and ended up hurting themselves-- or worse.
Seems like the same person who thinks a pair of pliers is a power tool, usually has an attorney, so "Never say Never".
