I built one of these for my 7mm-08 Xbolt and it worked well, but required a little fitting so the collar would slide with the right amount of tension. Now for the 7mm Mag. Thanks again for the info!!

Another example of why I come to this site before any others when I have reloading questions. It has taught me much. In reality, it is kind people like Frank, who share their wisdom and knowledge with lesser beings like me. Thanks to the people at Accurateshooter for maintaining such an awesome site to share info!!

Made a couple of these for two different caliber chambers and they work great . As Frank said ; “within a .001 or so ” , and his comment is correct . Never got more than a .001 variation when taking a measurement . Great tool for neck length clearances .
Found out I had a extra .010 and it saved a whole bunch of trimming and let me “grow” the neck .005 longer . Hey ; can’t hurt anything …..

(slapping forehead with palm) Why didn’t I think of that? Obvious answer: Because I am not nearly as smart as I sometimes think that I am.

Just what I needed! I’ve used the Sinclair gage in the past, and went to site to order one for .25. As Zero wrote, the tool gage is $5.99 and shipping is $7.95.
Zero also has good points about letting case lengths extend. Just ensure to have that .015″clearance!

I’ve been doing this to all my chambres for a few years now for obvious reasons…
Longer neck is always better and who the hell likes trimming/chamfering and deburring ?

Also keep in mind that a gap between the neck and the chamber is not ideal because under pressure the part of the bullet that is directly above the gap will slightly swell into this gap upon being fired, then the swelled part of the bullet has to swage itself when moving forward… most likely not good for the bullet jacket and could even rise chamber pressure very slightly.

After going this to a dozen or so chambers I’ve noted I can let the brass grow 0.015″-0.025″ longer than the Max SAMMI spec leaving me 0.015″ safety gap.

Yes, RIP Frank. I’m very sorry to hear he’s died – the Forum and those of us who never had a chance to meet him will still mourn his loss.
