Loading Tribulations

I buy a rifle/pistol/shotgun and then do a load development with it to see what it can do.

I recently bought a Savage Hog Hunter on EE. This has a medium weight 18.5” barrel.

As per usual with a new rifle, I bedded it in the synthetic stock, them mounted a 16X scope for the load development.

The trigger had problems. Sometimes it would not fire the rifle. I took the action out of the stock and found that the trigger had been played with and the adjustment was set too light and buggered, so I could not add weight. I phoned Savage and they are mailing me some trigger parts. In the meantime, I have to pull the trigger 7 times to fire 5 shots. More practice. I get to mix dry fire with live fire.

I was also having problems with what seemed like a trigger failure, but the round came out with a dimple on the primer – a light strike.

So I took the bolt apart (and discovered someone had been there before me) and added a half turn of firing pin protrusion. It now has 100 thou. (75 is plenty)

Still a few light strikes. When I got home I measured some of the rounds that would not fire and compared them to the fired cases. The unfired cases were 17 thou shorter headspace.

No idea how I managed to do this. This is Lapua brass that got annealed. I sized it before annealing. Could annealing shorten a case? Or maybe I used a bump die thinking it was a FL die.
Anyway, I have another 150 of these short cases.

My next plan is to load the bullets long, so they hit the rifling hard and push the case head hard onto the bolt face. Hopefully they will all fire.

I tried Sierra 155 Match, Nosler 155 Match, Hornady 155 HP Match and Hornady 168AMax. The Sierra and Nosler 155s are all grouping under an inch (4895 better than RL15). The 168AM is about an inch, and the Hornady 155 Match are always around 2". This rifle does not like them. My luck, I have a few thousand Hornady 155s.

I can't think how annealing brass could cause that. Brass does not go through any phase changes during annealing that could account for significant dimensional differences. It will expand with heat, then drop right back to where it started when it cools.
 
Before doing anything with your ammo, check the head space in the rifle with a set of go/no-go gauges!
very possible that has been messed with as well as the trigger and firing pin.
 
When I measure the fired brass, it is exactly the right headspace. So rifle is fine. Barrel has a front sight. It is still vertical.

I am guessing I somehow pushed the shoulder back. Maybe with a neck sizer I thought was a FL die?
 
I agree that your resize efforts somehow over did it. I like your idea of seating bullets long to hold headspace against the firing pin strike, so you should be able to salvage the short brass.
 
Just got back from the range. I seated bullets long and the number of missfires dropped. So that confirms that short brass is an issue. The cases measure short headspace of 13 to 20 thou. They read 0 after firing.

Looking at the primers, they are not seated as deep as they should be. I think they are the last batch of primers I installed with my old, worn out Lee AutoPrime. I will run the remaining brass through my new Frankfort Arsenal seater, and seat them properly. High primers and short brass can both cause misfires.
 
The act of seating the bullet may have pushed the neck and shoulder back especially if the case was over-annealed especially if there was a lot of neck tension.
 
Perhaps fireform, using pistol powder, cream of wheat and soap. Projectiles are.pricey, you would be a primer and a few pennies of powder.

Jamming the lands isnt going to help with load development.

Too bad this happened, but it serves as a reminder. If this can happen to you, it can to any of.us.

I still have a hundred cases I have not loaded yet. They are undersized.

I am guessing that I used a die I assumed was a FL die when it was either a neck die or a bushing die and was capable of pushing the neck back. A FL die could not do it.

Yes, load development with jammed bullets is of no use, and match bullets are too expensive.

Fortunately I have a few thousand plated bullets that were very cheap ($65/1000), so I have started using them.

Over the last 45 years I have been reloading I have seen enough out of spec dies and rifle chambers - and factory brass - that they no longer surprise me when I find them.

If it was me I would neck the case necks up with an 8mm expander mandrel - or 8mm neck die - and create a false shoulder when you CAREFULLY resize the case just enough to end up with a crush fit in the rifle chamber. You could then use theses cases to work up a load with your expensive bullets.

That is an excellent idea. Thank you.

I will try that. I wonder if 8mm will make a big enough shoulder? I can set the headspace on the new shoulder about 4 thou long, to wedge the case in the chamber.
 
This is my favorite tool for necking up cartridge cases. It provides case necks with zero inside run-out.

Just got back from the range. I shot the 150 gr plated bullets, seated long, so they engaged the rifling. 10 each of 24 gr to 33 gr. All but 5 went bang.

My brass is now the correct headspace. I will pullet the bullets of the ones that did not fire and re-load with Federal primers. They will fire and form.

The 24 gr bullets shot into a 1.5" group. By the time I got to 28 gr the bullets would not stay on paper.

So I also got some useful loading data. It would be neat if I could get these cheap plated bullets to be good 100 yard plinkers.

I will try a better powder than 4895. I have some 4i98 and WC680.
