Variances in ejectors. A Question.

[imarangemaster]

I thought the improved slide was to increase cam timing and delay bolt opening slightly. I think the brass angle of ejection is more a function of ejector face. I have a spare headspaced Inland round bolt with a type II ejector in it. I should try that and see where the brass goes

It's a combination of things about the late (TY V and VI) slides. Bolt stays open longer because the newer slides traveled farther before contacting it.
This is the increased DWELL. Another change was in the slide's bolt/cam area, by being angled forward it also improved the ejection angle, among other things.

I'm happy as long as I'm not catching brass between the eyes !

BTW not all type V slides have the increased dwell angle mods.

So what does the ding-danged "hook" extention over the chamber area do?

Thanks Brian,
After re-reading that.......I see my error.

One of the other minor problems with carbines was a chamber flash from burning powder that interferred with vision during night shooting. The forward angle helped to reduce the flash as did the increased dwell time.

Actually jimb the angled cam are only changed the extraction angle when the spent shells contacted the slide. The additional .040" milled from the rear wall and the right lug area was the only thing that affected the dwell.

Type V and type VI slide can be found with and without the increased dwell mods and on a limited scale earlier type slides can be found with the mod as well.

Inland was the one that came up with the solution to the chamber flash problem. The remedy was approved in November 1943.

Some of the old timers may recall there was a six digit Inland on GunBroker about a year ago that had a type V slide. Everyone assumed it was a partial restoration due to the slide type. One of the guys that used to post here frequently snatched it up because he knew Inland was using the type V slide on a limited basis much earlier than all the books say they were. Turned out the carbine was all original with original finish and the serial number was only a only a few hundred off the lot of test carbines.

That was find indeed. I was fortunate enough to see pictures. We continue to learn.
