new brass & spring ejector

[walley2960]

Question for the pros. Is it necessary/wise to remove the spring ejector when fireforming. In the past I have both jammed and removed the ejector to ensure that the case head was firmly against the boltface. Just looking for opinions on whether or not this is necessary to help achieve the best brass to chamber fit with the min firings. Thoughts?
Thanks in advance.

Everyone I know and shoot with have removed the spring from the ejector. Theory is that it puts uneven pressure on one side of the casing head when casing is chambered. Besides, it saves you from having hot casings flying around and keep the bending of the necks upon impact with the ground. Not really sure how all that actually improve accuracy, but it works for me in my rifles.

It depends on how your brass is preped for fireforming. If you neck up, oversize and form the forward part of the neck to the finished size until the bolt will close with some resistance, it won't need to be removed.

thanks for the replies
To clarify the question some. Will it reduce the number of firings needed for brass to reach the full size of the chamber. I will use the ejector for hunting etc.. . I don't mind removing it or perhaps just the spring when shooting at the range if it will help to make the best longest lasting brass. Thoughts.

I can't think of any good reason why an ejector would shorten brass life. As was stated earlier, if you use a false shoulder to fire form your brass it should not matter. As far as needing to fire form more than once to have properly formed brass l feel it would depend on how hot your load is and what you're trying to form.

As usual I am struggling to ask this properly. Rem 700 stock spring and ejector. .001-.003 neck tension depending on rifle and dies. With brass that has standard thickness neck. I do neck turn enough to take off the high spots. Using the jammed bullet to hold the head of the case against the bolt face so that brass growth occurs away from the case head. Case head separation is what I would be looking to prevent. Min firings to a fully formed case is what I am looking to achieve. I will bump shoulder back an amount where I can just feel the chambered case for my normal die adjustment loading routine. Thanks Again
