Hornady no boom boom

Those strikes are pretty light, clean ALL the oil and grease and garbage out of the bolt and I would bet your problem goes away. You said 'new to me' so I am guessing you didn't detail strip and clean the bolt. Lot's of people believe that the bolt and firing pin need lubrication internally and they happen to be dead wrong. A very light coat of very light oil that gets wiped off before assembly is all the firing pin, bolt bore and spring should have on them. It is NOT lubricant, it is corrosion prevention. If the previous owner did what a lot of people did and added oil each time he took it to the range the bolt is likely full of oil and residue.

I did notice some grease when I cleaned it. But it's all clean dry an a light film now.

I'm still lost I ran these same rounds in the model 7 an no boom
 
You did take the bolt completely apart and clean it? If you don't have the ability to take the bolt apart you can try hosing it out with some brake cleaner over paper towel until there is no color coming out, let it sit a bit and do that a couple more times. I read that you had two different ammo that had no boom in the same rifle, is that correct?
 
Bergara bolt was fully broken down an cleaned as far as I could without knocking pins out.

Yes I used all Hornaday
150grain failed.
139grain failed.

Took failed rounds into Remington Model 7 7mm-08 tried them there. Still failed. An I know the model 7 is good.

I'm thinking it's a combination of bad primers an dirty bolt.

I spoke with someone who told me the firing pin springs are weak am that if I call bergara they'll send me a longer one.
 
Now I gotta try to get ahold of bergara get a new pin sleeve

I'm just hoping it'll work better after I cleaned it well for this weekend hunt.

Yeah I know I know I'm taking a risk that I may ruin the hunt but what's life without some excitement.

Those are definitely light strikes. If that's after both rifles attempted to fire them I'm surprised. I would be getting out the calipers to measure pin extrusion on the bolts. Also checking the ammo itself to confirm it's the correct length from base to shoulder and compare with fired brass from same gun to see if there might be headspace issue.

When I get back from OK on Monday I'll break out the calipers an do just that.
I'm going to do a single shot check an then it's game on for Russian roulette. It gives the deer better odds anyways.
 
BTW is that the first time you've had the primer flow with the Remington? The primer itself isn't flattened or showing other signs of pressure. If it happens more than once might need to look at getting the bolt bushed.

Doesn't have to do with your issue but first two elk my younger brother shot he let them hear a dry fire click before actually loading a round and then shooting. Of course not on purpose. He said he just wanted to give them a head start. Good luck on your hunt. Hope it works out.
 
Do the failure to fire rounds have gun powder in them? If you have any unfired rounds and can wrigh them--- compare the weights......I have seen some like that BUT they were a friend's reloads and he forgot to put powder in them--- the primer actually fired off but the bullet never moved.
Just 1 more thing to check into anyway. I highly doubt it's the case but it's something to check
