Remington's are known for having extreamly long throats...Quote:

The excessive throat didn't seem to matter as far as accuracy was concerned.
I have boxes of plaques I won with it shooting many LE/Police matches.
I'm getting a measurement of 0.093" between the listed overall length and when it is touching the lands.
I've been reading that magnums, because of their slower burning powders, require more of a gap to get the bullet up to speed before hitting the resistance of the lands. Otherwise, if it's too close, it would cause too much pressure.
I think I will start off with the listed length until I get my powder charges sorted out.
Thanks for the wealth of information given!
Not a bad idea at all to do it that way and probably the safest.Quote:

Just an FYI to help keep in perspective all the fanatical/particular ways we are with regards to details when reloading......I have taken spent cases from a DM rifle, re-primed, re-loaded and seated bullets without any re-sizing at all, and shot those at long distances into water filled milk jugs with amazing success.....go figure.

/// You must have at least resized the neck, or the case would not have held the bullet at all, it would just have fallen out or into the case till it touched the powder.
I would expect the possibility that you mention on factory rifles more so than on custom and have even checked my factory rifle spent shells that way sometimes in order to set the neck tension I desire and get an idea of chamber tightness, and you are correct, some will fall through but many won't. Less so on precision built rifles.Quote:

Try it sometimes, I found it enlightening considering how particular/precise many of us re-loaders are when doing every single step.
I no longer am as quick to first suspect the primer, dies, neck tension, etc. as I once was. I have found most of the issues with the holes in the target are me.
My Ruger #1 is like that. Being single shot I don't have recoil or trying to work it thru the action to move the bullet around. There is just enough spring in the casings to hold the bullet, but it isn't a practice that I recommend for hunting.
You and Jaycee bring out a good point regarding neck tension, especially in "practical use".Quote:

I agree it's not a good wild game hunting practice.
Personally, I am partial to the Lee neck size die and have found it consistent on neck tension.
Anyway, Maximus44, hope it works out well. Remember, regardless of the powder burn rate selected, any "jump" to the lands is safer relative to that bullet/powder combo touching or jammed into the lands.
Let us know how you and the Win Mag do.
Unfortunately you didn't chronograph the loads (or did you ?) . It would be interesting to see how much of a difference there is (velocity-wise) between a tightly held bullet and a loose-one . --- There definitely would be LESS initial pressure (until the bullet does contact the rifling) .Quote:

I also feel that hunting loads need to cycle smoothly in a rifle. Make shure they all feed properly and chamber well. What works single loaded off a bench rest is not always the best setup in a stressful hunting scenario. I have seen people seat bullets at extremes and use loads that push the envelope to the point of sticking. If it doesn't cycle like a factory load before firing and after it's not for me. Within truthful hunting ranges no animal will feel the difference of a few fps but you will be pizzed if it doesn't cycle smoothly.
