Bergara called me a pansy - Any ABQ area 300WM Shooters to prove it?

Chamber Tooling chatter just forward of the belt. Smith diagnosed, polished…presto, smooth as silk ejection, no belt lift. .257 wby mag.
That’s what I thought. Mine was rough on the upper 2/3 of the walls. GAP redid the chamber free of charge because they pitied me

Alright, borrowed my wife's purse and the bolt opened. Here's a comparison of the spent brass from the Bergara, factory and a new Tikka:

Oddly, the Bergara neck is oblong compared to the Tikka???

@Chingon have you got the grain and OAL on those same cases? As in, were they all same grain, seated to the same length? Propellant and primer should be considered too. I think you’ll have a solid point when all variables are consistent.

Looks like some rubs/scrape marks on the Bergara case just above the belt. That neck is certainly out of round also. I’d bet the chamber is non concentric also.

Looks to me to be the problem as well. I’d be going up Bergara’s arse to have them remedy it if I were Chingon

I forgot about primer too. What did the stuck case primer/case head look like? I started a thread on here after a factory box of Federal gave me my first ever blown primer.

Heavy ejector spring will slightly dent a case mouth. Just a thought. mtmuley
True but normally they are dented inward from my experience. Also they can be dented from the ejection port if it’s smaller or the ejection angle is too much.

Primer looks normal, no cratering or ejector marks.

I am in Belen just south of Albuquerque and might be able to help you out.
I appreciate the offer and will follow up as needed. Right now the Bergara is stripped back down and I'm going to take it back to the smith to get the action cast.

Ok, in my quest to die on this hill, I went out and bought the lightest, most recoiling 300WM I could find - a Tikka T3X Superlite without a muzzle brake. Weighs in at just over 6lbs naked, 8lbs with scope.

Paired it up with my Leupold VX6HD 3-18 scope, and shooting from a light sled. I've been slowly breaking this barrel in, and it had only about 9 rounds through it so far. This is the first batch of decent ammo I've tried. Hornady Superformance SST 180gr factory loads.

First group after 1 fouling shot:

It seems like I am capable of sub-MOA shooting, so maybe now I can send Bergara a link to these posts.

Thoughts on the new Tikka: Man, this thing is nice, and the weight will be a joy to pack around. However, this pencil barrel heats up REAL fast and shooting for groups is an exercise in patience after the first couple of rounds.

I'm going to thread the barrel and see how it likes my suppressor in the near future. If it doesn't, I'll go ahead and slap a brake on, adjust the trigger down, put on the pistol grip and see what ammo it likes best. Hopefully it's capable of 3/4 MOA!

Companies have become very slow to admit their mistakes. I’m very weary of this. A company can have the best marketing ad but it doesn’t mean anything if the company doesn’t match. You would think Bergara would not be so reluctant to help. That’s too bad, I’m sorry.

The worm turns...

So after the failure to eject fiasco, I took the rifle back to the smith and he found a slight burr, likely caused by a headspace gauge. He gently ran a reamer through it by hand, and that seemed to fix the issue with feeding/ejecting.

I also went out and bought some new ammo - one that Bergara claims to have proofed it with, and some Barnes VOR-TX 180gr that was suggested.

First group with DRT 175gr Terminal Match ammo with the Bergara:

Second group with the same ammo:

Averages out to 1.14 MOA :unsure:

My Tikka didn't like it:

I was going really slow here, so only had time for one more group with the Barnes:

More testing to come...
