If I use a new sized case and start a bullet in the case and close it in the action,
You can't use a sized case.
___________________________________________________________________________________________________________________________________________________
You have my permission to use sized case, a neck sized case, a full length sized case or a partial full length sized case with neck sizing, it helps to know the difference, it helps when reloading to be able to keep up with more than one thought at a time.
bhw4235, You can use sized cases, because? Bullet hold!, I want all the bullet hold I can get, and? I am the fan of transfers and standards, I could shred the neck of the case and make squid neck cases, that works if all I was going to do was talk about it or look at them, I want to take a measurement from the chamber to a test case to the seater die that can be zeroed (all of my seater dies are adjustable in thousands and zeroed to .000 off the lands or to any dimension I have a standard for).
You are also allowed to use a fired case, my first choice would be to neck size for bullet hold, I would not waste my time pinching the neck, again, I want ‘ALL’ the bullet hold I can get, buy if I did decide to pinch the neck I would accept readings that would be all over the place, meaning I would pinch the neck of one case and use it over and over and etc.. Because?
Again, I drill the flash hole/primer pocket to a diameter that will accommodate a cleaning rod, I then seat a bullet that is to be used for loading, the depth of the bullet is to be seated deep enough as to avoid the rifling before the shoulder contacts the shoulder of the chamber, after chambering the test round, I push the bullet out of the case with a cleaning rod until the bullet contacts the rifling (if the bullet is pushed out of the case before the bullet contacts the rifling get a longer bullet, if that does not work, work up 200 + rounds in groups of 5 and head to the range to determine what narrow window of combinations of loads the rifle likes, there will be a few bullets with starting loads that shoot good but will not shoot better by increasing or decreasing powder charge or by increasing or decreasing the design or weight of bullet) And I was asked why and how something like that could happen and I say/ask to see the reamer and the answer was “we broke it, by accident” and I say someone heard about Weatherby’s and the long throats, instead of saying “interesting, very interesting” they purchased a neck reamer and got after it.
Back to pushing the bullet out of the case with bullet hold, after removing the test case from the chamber it becomes a transfer, the transfer does not need to be placed into a Hornady/Sinclair, home made dial caliper with a round hole in it, BUT! if the transfer was placed into the Hornady/Sinclair, Home Made devise, what would the reloader do with the measurement? The measurement needs to be transferred to the seater die, there is no harm in looking at it, I suppose, the point being the Hornady/Sinclair, dial caliper home made devise with the hole in in from Home Depot is not necessary, nice? Yes, just not necessary.
Again, all I want to know is ‘Where are the lands? What is the distance from the bolt face to the lands and it is not OAL or COL, or COAL, after determining measurement from the bolt face to the rifling with the transfer, I place the transfer in the shell holder, raise the ram then adjust the seater down until the die/crimp contacts the mouth of the case, then stop, back the die off 1/2 turn then secure the die to the press with the lock ring. After securing the die to the press I adjust the seater stem/plug down until it contacts the bullet, then stop and secure the stem/plug to the die with lock nut on the stem. THEN I use a height gage or dial caliber to measure the height of the stem above the die, after measuring the height of the stem above the die, I adjust the dial caliper to .000 and call it .000/zero off the lands, again without a Hornady/Sinclair or home made too,
After adjusting the seater stem for .000 I use the .000 as an Index (write it down) then lower the stem and measure from .000 for seating bullets off the lands. Example, if I decide the adjust the bullet .030 off the lands I would use the dial caliper to adjust the seater stem from the .000 index .030 thousands, not forgetting to secure the locking nut on the seater stem/plug.
With bullet hold, the transfer can be stored for future use, again, my rifling contact point does not move, on my 30/06 chambers the contact point is always between .300 and .308, but that is for another day, so if you choose to use cases with sized neck in any combination you choose, it is OK with me.
