Can I safely run an Omark without the ejector in place in the bolt?

There is nothing to say you to have the ejector in place the hole will best been filled to prevent damage to brass though

thats how i run mine.
i put a brass bolt in a drill and spun the thread off it,cut it to length and put a notch in the side for the retaining pin.
just make sure what ever you use is flush with the bolt face or you will get a dent/lump in the case face.

It is not a requirement to block the ejector hole.

Same here

When i was using my 308 barrel with a 175 on top of a kg of 2208 I got bad marks on the case head .
Closing it up made a big difference.

Some could argue the point that less burn would have also fixed the problem

Thanks. I am more worried about my head than the brass.

I hope if anyone is loading an Omark to the point that they are flowing brass back into the ejector hole, that they are never at the same end of the mound that I am shooting. Regards Malcolm.

Dont own use an Omark anymore, long since moved up the food chain, but, with 155's my load was at the time very low, I was only doing 2930 as I was just using it at the club out to 600 yards. I cant remember my loads but it was something like 43 or 43 grains of 2208. Anyway I ended up with circles on by brass due to removed ejector so it does not have to be a hot load to do it.

They do have quite a large ejector hole which is why I asked the question, I did think it may leave a mark or lump on the rear of the case, but was mostly concerned about it being unsafe to my wellbeing. I really only want to try it as a bit of an experiment.

43 of 2208 would be merely dribbling out the end of the barrel, I reckon 2930 would be a bit hotter than that.

Only if your load is HOT!!! The fitted ejector is held out with a spring which when fully compressed puts the plunger face below the boltface.........so the "lump" you mention will still happen ejector in or out!!!!!

Not with the rather tight Archer barrels that were for sale at the time, that was the speed.
