.308 Reloading Help!!!

I cannot get the bolt to close on my Remington 700 Bolt Action Rifle. I resized the brass exactly as recommended by Dillon. Ive been gradually going further down trying to correct the issue to no avail. Im down to the point where the die is literally touching the shell plate and im still not getting tge brass to size properly for the bolt to close on it. I have a Dillon 550 with Dillon .308 dies by the way... Ive invested too much time and money into this and im very aggravated that I cannot get it to work properly. Can someone, anyone please help me.. im ready to just sell everything gun and all and give up on .308 for good!

RE: .308 Reloading Help!!!

First, be sure you are using sized, empty cases, to test chambering. This limits the variables involved. Next, measure the cases after resizing to be sure they do not exceed maximum case length. Cases increase in length after being fired and resized.  Finally, you may need to turn the die down up to another 1/4-1/2 turn after the die contacts the top of the shellplate. The handle may need to go "over center", to size the case enough to fit your chamber. A headspace case gage would make all of the above easier.Stock#12867

I am sure that someone might have suggested this option - trimming the case?

RE: .308 Reloading Help!!!

Have you tried just neck sizing since this is a bolt gun? In my limited experiance with loading rifle, my friend only neck sizes and trims as needed for his bolt actions and full length for his autos. As long as the cases in question were fired from his bolt gun since the brass will fire form to your chamber. Sorry if this info isnt any good, but he always out shoots my semi auto at longer distances so i figured it was worth a try. Somebody here please correct me if i am wrong. BTW, we both load on dillon 550b machines.

Mr Dillon, I agree with everything you suggest (you too 'alexyas')....except I wonder if turning the resizing die further down lower than "touching" the shellplate will put strain on the shellplate, and possibly bend/break something?

I am new to the Dillon 550, having loaded only a few 44 Mag & 38 Spcl the past two days since I got the press.

One other thing I was thinking: If he has the bullets seated to high, and touching the rifling? Or maybe try a different 308 resize die?

Also agree with you Mr Dillon about the case gauge. As soon as my budget allows, I need a few gauges, among other nice-a-ties.

So far, I am happy with the 550B.

Thanks to the Dillon crew for this Forum.

Excessive bullet crimp can slightly bulge the case, causing feeding problemsas well.

Are you using new brass? Or have you gotten brass 1X shot from someone else?
My friend has an M14 and a .308 bolt gun. He cannot use the M14 brass in his bolt gun no matter what he does to it.
So he keeps the brass separated.
He can use the bolt gun brass in the 14. Once that is done though, he cannot go back to the bolt gun with that brass.
Just a thought. Hope that it helps.
Don't give up on the 550. I have processed thousands of rifle and pistol rounds with mine. Great machine and customer service too.

I reload for the .308 with my new to me Dillon 550. Since I am shooting 2 M-14's, I pay special attention to my brass. I have found that since I do not have Dillon Dies for sizing, I use me single stage press to de-prime and re-size my brass before I run it on the Dillon to re-load the brass. I also double stroke the brass when I size it to make sure that the brass is the correct size. The chambers in both my guns are tight and I have to make sure the brass is correct or I have feed issues with the rifles. You might try a small base die to re-size your brass.....it takes it down to the small end of the brass size parameters.

RE: .308 Reloading Help!!!

You really need to figure out what the culprit is before you give up my friend. There are several issues that can prevent the bolt from going into full battery. Your post here is like going on a computer forum and saying "My machine won't boot. What is wrong".
First thing's first. No matter which machine or brand you use you need to get some gauges. I would recommend the check gauge, an OAL gauge set, a headspace gauge, and I like a concentricity gauge...
Not only are these going to let you load safe ammo but they will allow you to customize the bullet for your exact gun. It's the difference in buying a pair of cowboy boots from Cavendars off the shelf and having a pair hand made off a form of your foot in Austin. Every Remington 700 is going to be different. There is a range of tolerance when they machine those chambers and you're going to need to measure yours to figure out the best ammo fit.
From what you're saying there I'm going to GUESS you have an issue with either bullet seating depth, OR head space. If you have some off the shelf ammo that will go into battery use that as a 'control'. Measure the entire length of the round from the ogive to the headstamp. If the bullets you make are longer that could be your issue.
Another way is to take a round you made on the press, try and load it, put just a little monkey arm on the bolt and take the round out and inspect the bullet with a magnifying glass. If it's putting marks around the ogive or pulling the bullet out of the case a bit you're seating depth is too high. But be real careful in dropping it because the more you seat, the higher the case pressure. Use lower grain loads until you get this figured out.
My final note is that you MIGHT be best off putting the machine aside for a while and doing some research. Keep in mind you are building little bombs that can take your face off at a rate of about 800 per hour. You need to know this stuff inside and out cause you could really F#$K yourself up if you do it wrong. Case specs are easy to find. Measuring can be tricky. You need to get to the point where you can trouble shoot this stuff. And if you're trying to reload on the cheap or because Walmart is out of .308 sell that chit on ebay and make a profit, or invest in the gauges. You will need to inspect your ammo for every. Gauges are your lifesavers.

I had the same issue with my Dillon die. I couldn't crank it down enough. I sent it back to Dillon and it works great now. I think something was wrong with the die.

I had the same problem and i had to switch to small base dies even though it was a bolt gun. This fixed my problem
