What are we calling a failure here? I know a guy that calls SSTs "super soft turds" because they haven't exited regardless of the fact that they resulted in dead deer.
I had a very similar situation last season but it was a 130gr mono out of a .270 wsm. That did exit but zero blood, guts and fat just plugged the holes. All that energy and penetration to have the exact same result.
I bought it with 150k and have not yet. If I were in your shoes, I'd change it every 50k. It's a pain to do so if you're not handy with tools be prepared for a bit of sticker shock when looking for quotes. I got quoted 7-800 for a pan drop, new filter, and replace fluid.
Cautiously optimistic Vikings fan checking in here. I've seen these frauds start seasons like this before only to wind up circling the drain so I'm just enjoying the ride for now.
