AIA #4 M10 Ejection

[Alfred]

I've found that the out of spec Lithgow action I've mentioned before, which I'm considering using for a sporter project, will eject rimless cases very nicely. This particular action has an odd extractor and doesn't handle the regular rimmed .303 cases well at all.
The No.1 isn't a good action for a cartridge like the 7.62 NATO but should be strong enough for the 7mm, in the lower pressure standard loadings though not the loads that puish the SAAMI max pressures for the 7mm, or similar less intense cartridges.
I checked the action with empty 7.62X39 and these also ejected nicely.

The No.1 action converted to .45 ACP works fine with that rimless pistol cartridge.

There are flat spring loaded ejector studs or tabs run through slots milled in the receiver wall that are used with a number of cartridge conversions of the No.1 and No.4 actions.
The No.5 was used as a test bed for the 7.92X33 and the .280 Enfield assault rifle cartridges and possibly a few others. If I remember correctly these test bed carbines had been altered for extraction and ejection, but the magazines were not altered to feed the shorter cartridges, test firing being as a single shot only.

Could I respectfully ask that this thread be moved to the NON-Milsurps General Discussion Forum as that is about the only appropriate place for more discussion about this commercial model rifle here at MILSURPS.COM

Thankyou,

I large part we agree that the M10 is not a Milsurp or an Enfield product, but as the only sucessful civilian bolt action based on an updated Lee Enfield design it has some interesting points.
Also previous postings about this rifle have served to warn those considering buying one for competition that it is unlikely to be accepted in service rifle category, so this may have saved a few prospective buyers from an expensive mistake.

I've always been more interested in the mechanics of antique rifle actions than their shooting qualities, one can always find a more modern rifle that will shoot as well or better.
Due to a long ago injury the short actions are of importance to me in particular, Mauser type bolt actions are awkward and sometimes painful to operate. Every bolt action rifle or shotgun I own has a rear locking short throw bolt action.

PS
Does anyone remember a short lived para military 5.56 bolt action, mid 90's I think, that used a rear locking action?
The rifle was designed more or less to serve as a Volks rifle type for civilian use in NATO countries. It used the M16 magazine and an action similar to the Enfield, though it had no other outward resemblence to the LE.
I don't think they sold many, the volks rifle idea being outdated.

In the US the Springfield Armory M1-A is used in service rifle competition.
It is not an M-1. It is a much modified commercial clone of the M-14 yet it is permitted in military matches. It is possible that at buyer of the AIA rifle can have his rifle modified or perhaps AIA will modify one of their production models to meet the service rifle criteria. If that happens the M10 rifle would be competing along side #4s.

I have always been curious about the competitions fired with the #4 rifles. What inspection is required of the rifles for competition?
1. Trigger pull
2. Sights
3. Weight
4. Barrel
5. Caliber
Are #4s required to compete against civilian versions of the currrent service rifle such are the AR 15 types used in the US?

The M10 could easily be modified to meet most of the #4 requirements, especially the sighting requirements. What is to stop a competitor from modifying a #4 with a modern bench rest quality barrel and chamber?
On one of the other threads there was a #4 modified to use what looked like a Canjar trigger. Are there any restrictions on these modifications?
