problems with reloading for Model 14 remington

[zacharoo]

I have a model 14 remington that I have been hunting with this year. It is a 30 remington. I am using the (old standard ) load of a 150 grain RN hornady bullet in front of 30 grains of IMR 3031 with Remington primers. Good accurate load have killed twoo deer with it so far. The last bullet I fired had a primer backed out about the thickness of my finger nail. NOW WHAT!!! Is that to hot a load with the new powder that IMR makes or what?

Your load is not excessive, at least according to a couple loading manuals I glanced at.  Could just be a loose primer pocket.  I would not worry unless it is a continuing problem.  I have used IMR 3031 in several cartridges since I began reloading in the mid 70's, and have not noticed any observable change to the performance of this powder.  Have you noticed excessive case stretching or signs of case head separation?  (TIP- bend a paper clip, and run it on the inside of the case, near the base.  I you feel a slight "notch" that is a sure sign of pending separation, especially if you also see a bright ring on the outside of the case, in the webb area,)  A quick check of headspace with a go / no go gauge at your local gunsmith wouldn't hurt.

Like Larry said,you also might be oversizing your brassTry sizing til you just get the slide to chamber and close the round,then just back it down a little bit more to insure fail safe chambering.Also make sure all your brass is within length specs.

I had an old Remington 14 in 30 Remington that I had the same issues with. Occasionally it would have a primer that looked like it backed out of the brass. What you are experiencing is low pressure. Your load is on the bottom of the book. Max pressure for the case is only 38,000CUPs to begin with. So your pressures will be considerably lower and even possibly erratic. You might consider going up with the powder load or do like I did and accept the fact it's going to do this occasionally. I loved the old Remington but unfortunately someone decided they loved it even more and offered me way too much money for it.

Will it hurt the rifle if I continue shooting it like this??/

As it was explained to me by the good folks at Sierra, when the firing pin hits the primer, it drives the brass forward against the datum line of the chamber. As the powder builds pressure, the case grabs the chamber walls but there's not enough pressure to push the case back against the bolt. Obviously, we aren't talking about big measurements here. Because the case can't move back, there's nothing to stop the primer from backing up until it hits the bolt. Per them, it won't hurt the gun at all. I ran several hundred rounds thru my Model 14 before it went away.
Really wished I never sold that gun. It's the ideal kids hunting cartridge and gun. Small, compact, and same power as the 30-30. I've been looking for another one in 25 Remington for several years now.
