Are you meaning ejector instead of extractor

yes. I meant "Perhaps the extractor or ejector spring". I haven't played with either on a carbine. I know there is the added dynamic of the slide handle geometry, but otherwise the principles of ejection are analogous to most anything else mechanics-wise. 1911's I've tuned the ejection on plenty. Changing the ejection pattern is combination of the geometry of extractor (how tightly it holds on to the case) and the force at which it strikes the ejector stud (the balancing the buffer spring and recoil forces on a 1911) - or analogously the ejector spring force on the carbine.

LOL...if only carbine brass were as cheap today! I guard mine like gold, and I certainly never go M1 carbine shooting without a kiddo or three to take turns scrambling for it as it falls. I scored a case of PPU 110gr. a couple years ago at a good price. Berry's is starting make/have in stock their 30cal plated round nose again - so I'm all set but for large quantities of brass.

Might want to see if you have the latest style Ejector in the bolt.
But before changing anything read on:

One of my shooters ejects straight back looking for my forehead, as it gums up it looks for my neck. I Can't recall which carbine that one is but it's marked on one of the carbine range cases. While trying to duck brass one day another ole timer getting a kick out of watching me squirm asked if I had a mosquito head net. I smiled and said say no more. It was a Light Bulb moment Now also written on that range case is Mosquito head net. I probably had half a dozen tucked away in the boats and tackle boxes for our notorious black flies, no see ums and deer flies. Honestly they work great to deflect killer brass. Just never gave one a thought for use at the range instead of playing rope a dope.

Thx for sharing your Great day.... Valentines.. and to have the Daughter out there. Makes memories, time goes by too fast. Plus You Can't beat young eyes looking for treasured brass. Maybe some pictures of her shooting next time? You know, before she's borrowing the keys for the car

Cheers

I know for a fact the ejector spring, plunger, and recess in the bolt are cleaned and oiled to spec as part of my own process. It could be the spring though - I've seen many an garand's and AR's that are slightly kinked, which could cause some unwanted friction. I'll start there. replace the spring, more closely inspect the geometry of the extractor for burrs or wear, and try again.

I'm very proud of my little girl. She has been through a lot this last year, and came out on top. Over the 2021-2022 holidays, she got very sick. Just after Christmas, after she had lost over 30lbs in 2 days, we landed in the E.R., and spent the next 2 weeks in the ICU - Type 1 diabetes at 10yrs old. She aged a decade in those 2 weeks. While saddening that this disease robbed her of so many things, like a carefree childhood they all deserve at that young age, she has grown this year into a more responsible little adult than many of my college students. We try to keep our kids' internet presence null until they are old enough to choose what to share for themselves (when they move out ), but sometimes I just can't help shouting to the world how proud I am! Thanks for the opportunity.

looks like I already have the late type ejector with conical bevel all around. I have a couple more springs/ejectors on the way to play with.

Changing to a late op-slide (angled deflector lug) will help with the direction of ejected casings. Can't tell by your picture if you have an early or late.

I have a 10-year-old grandson who has also been robbed of his childhood by T1D, diagnosed 3 years ago after an observant school teacher noticed that he was needing to pee way too much. Definitely makes them grow up way too fast!

Yep, looks like the late style. When magnified up you see a lot of things that may not be anything. Looking at your tip looks (?) like some residue around the top side... per the pic orientation. Does it press in ok?
Sometimes a gummy chamber will hold just enough to affect ejection angle.....
And sometimes they run completely different the next time out.

I've got to the point where as long as their running and extracting I'm happy. But still keep my Mosquito head net handy. If it's a carbine benched ejecting out at 3'0 clock I can catch most brass with that head net propped to the side.

Keep us posted how she runs.

Bless your Daughter

Strength of the load also affects ejection placement. Depending on what load I shoot (as in both projectile profile and powder charge),strong stuff over my head and right shoulder at 5 o-clock. Weaker loads around 2 and 3 off to the right.

I looked and a new ejector (with spring) was what it took to fix my Inland - wow that was 14 years ago! Mine were both the one in the 3rd picture Charlie shows. I installed a new spring on a carbine ejector recently and it was not easy !!. If you put in the spring only, make sure it's a genuine USGI spring. Let us know if you figure out an easy way! Younger hands ought to help a bit. More later .... - Bob

Here's the slide handle. I'll be leaving it alone and tweaking all else first. I don't think the brass is hitting the handle at all. The ejector moves freely when depressed. My other carbine (NPM) has the 45 degree bevel type ejector. Comparing the two, the underwood feels a bit grittier when depressed. Could be a kinked spring, or some gunk or grit I missed when I put it back together. I wish I could find some slow-mo footage of carbine ejection. There is a really nice high-speed footage of a garand on this forum (and YouTube).
I don't have any control over the loads...yet

The casings would not hit the slide handle, they do hit the slide deflector lug, you have an early slide.
