Neck tension

[Guest]

Before loading New Remington cases for my 300 Ultra Mag I usually need to true up the Case Mouth openings due to shipment damage etc. The method I use is to run them through the resize die but not entirely as to totally resize the case. Is there such a thing as to much neck tension to the bullet installed using this procedure, and no I'm not crimping the bullet. I've never had any issues.

I do the same exact thing but I add a little mica or imperial sizing wax to the inside of the neck. Then use a lyman VLD chamfering tool to restrain the necks from stripping the jacket material off. You're fine with your process Don.

I am same as POP I tried "one shot" last reloading cycle and prefer the Imperial. Graphite also works well with just a drop of fine oil. I have had one misfire in 50 years of loading and I believe that was a result of dirty fingers. They will get dirty and pick up some oil and other containments during this process. I "always" wash and dry my hands thoroughly prior to seating primers. :grin:

I've been using one shot, and I like it so far!

Don,

I do the same as you and do a partial full length resize with new brass. I also chamfer the inside of the mouth and have never had a problem. I don't have to worry about too much neck tension with your process.

Thanks for the replies,
You can't be to careful when reloading in my opinion. I have always done it this way with no problems. Makes me feel better anyway that other posters use the same process. I tend to get somewhat anal about loading this Ultra Mag due to the large volume of powder used, I try to be very cautious about pressures when shooting max charges.

With lube inside the case mouth, what keeps the bullest from moving around? :?:

You lube a little you resize and then tumbling or a Q-tip comes into play. A q-tip when using imperial sizing wax or mica, Neither will contaminate the powder or primers for that matter.
