removing the plunger

I read a blip just now about a guy that removes the ejector plunger from his bolt for maximum accuracy.

Obviously this isn't advisable if you're using the rifle as a repeater. But, is there any harm in shooting without the ejector?

And, is there really any benefit supposing you're going the whole 9 yds with brass prep, load development, match chamber, etc?

Also, did I miss something? Or, would you need to weld the hole shut and reface the bolt?

I have a Stiller TAC-30 and am looking to squeeze out a hair more precision. And, I can't see how the ejector aids in that regard.

thanks!
Richard

    You can just pull the spring and replace the rest. Because it puts tension on one side of the case many people believe it kicks the bullet/case at a angle.

    If a chamber has to much head space it can help.

    The problem is that it leaves part of the case head unsupported and if shooting hot loads can
    damage the case head.

    Most bench rest shooters neck size only, so it does not come into play.

    I have made a few of these modifications when nessary (Due to excessive head space) by
    installing a steel pin the same size as the ejector and a little longer than the bolt face to the bottom
    of the hole dimension, cross drilling the pin using the ejector role pin hole as a guide,Pinning it in
    place and then facing it off flush with the bolt face.

    This way it can be removed later if you want to, and it supports and leaves no marks on the
    case head when firing hot loads and does not require re head spacing after removal

    Note: fire forming and minimal sizing will also prevent this condition.

    On single shot rifles it is OK to do this Unless you neck size only, then it is not nessary.

    Doesn't seem like it's worth the effort.

    I ordered an arbor press and wilson micrometer seater. Hopefully, tweaking seating depth at the range will be a better use of time.

    I never had a rifle like this. So, it's hard for me to say when it's time to quit messing around and just shoot.

    Thanks!!

    My frfiends shoot 6mm dasher, both of them have many records, the one just set 2 world records this last season, has his buddy all fired up, they are always messing around. He hits the range with test loads, then it is reconfirm, or new seating, or a custom bullet, or......

    How's it shooting?

    I think it's all about the game you wanna play. Some folks live an' breathe tiny groups at close range. Tinkering is joy. Some folks want screamin' velocities to make anything inside 500 yards evaporate.

    For me, a first round hit on a 3/4 minute target from 1200-1800 yards leaves a grin. Smokin' fur of any kind makes me giggle or shout. Shootin' anything off a bench....naah
