Bulk 308 Ammo Needed

[OregonEddie]

Does anyone have a recommendation on where to get bulk 308 ammo? I'm getting lots of jams with my reloads.

What types of jams are you getting, you might get the same results from factory depending on what's happening.

Weapon? Load data? Bullet weight/style/nose profile?

It's a DP-10. Hornady 150 gr ballistic tip. Rounds fail to chamber. Marks are present on the case neck. Full length resized with once fired, previously crimped brass.

Can you single feed a round into chamber and charge it to go into full battery?

 

[OregonEddie]

No, it won't chamber

Neck or shoulder? Did you trim to length after sizing?

Can you load a factory round? What are the shoulder and neck measurements? Does the case pass a case gauge test after sizing?

 

[OregonEddie]

I don't have any factory rounds, but I ordered some this morning. Cases were not trimmed, but measured in spec.

The neck seems to be the problem area. Is the neck wall
thickness something to watch?

It could be that the shoulder and or the neck are out of spec with being to long.
Do you have a case gauge?

Not yet

I'd start there and get one or if you have a micrometer than measure the case dimensions and compare to listed case specs.

Ok, will do.

 

[Local Loader]

This should help some.

A set of dial calipers are a good investment if you are to continue down the path of reloading as well as a case gauge.

I would contact the maker to see if they had a run of tight chambers. Chamber clean? If the chamber is tight, fouling that would pass on a standard gun might cause chambering difficulties. With a clean in=spec chamber, a set of Small Base Dies will fix such trouble. They will size slightly under for semi-autos.

Get one of these: https://sheridanengineering.com/product/308-win-ammunition-gauge/
The slotted type will show you exactly where the problem is so you can adjust your die properly or get a different die that will size your brass correctly. More than likely, you will find its the base of the case not being sized down small enough.

Both of the above. Without a cartridge headspace gauge, your ability to successfully roll your own will be hit or miss.

I like the Wilson gauges; the Sheridan looks good. I don't like the Hornady gauges.

You can do a drop test in a barrel in a pinch if you don't have a case gauge(after sizing before loading), plus having factory ammo to compare to is really useful.
As for gauges I've had several and I do like the Hornady ones myself. There are some that are adjustable but I'm not a big fan of those(moving parts mean more things that can break or go wrong) but they do have there uses and some people do like them.
A GoNoGo gauge would be a good thing to have as well if you are worried about the die settings, testing if it will chamber works in a pinch as well.
One thing I would say to do is to make 1 dummy round(or more as needed)(case with bullet only, no primer/powder) and use those to do barrel chambering test as that's the safer way to do it. Once you have one or more that works correctly you can also use them if you need to, to reset your dies.

If you need supplies and/or ammo I've got some or I know where to get it if I don't have it.
If you need some local help or just want a second set of eyes to take a look, feel free to get a hold of me.
