They're fantastic bullets. I also used the 143 in a 280AI for my mule deer last year. He dropped at the shot. It was a frontal heart shot and the bullet exited out on the inside of one of the back legs. All the petals were somewhere in the intestines.
No meat was wasted at all, except the heart...
Well, I went and dropped the stock off at the smith yesterday and after trying to find it for several minutes, he remembered that they cut and chambered the thing already!
My indecision was for nothing.
I had the 1.5-5 VX-3HD. It was a good scope. I had it on the WRONG rifle, though, so I sent it down the road. You wouldn't go wrong with it.
Good looking gun. I recommend getting that sucker bedded because even my 25-06 MkII had a split laminated stock.
From what I understand, they re-released the 280 Rem with higher pressures after a bit because they knew their mistake. It’s now at 60k PSI, still under the 270’s 65k PSI rating. The AI is rated at 65k PSI as well, which also gives it a longer leg up on the Rem in terms of performance.
