I took my POF Revolution DI to the range with three different types of ammunition. a 147gr, a 150gr and a 180gr just to see how it handled each. With a 1:10 twist rate, I was expecting the worst from the 180gr ammunition and I was correct in that assumption. I went through 15 of 20 rounds out of the box and they were everywhere on a reasonably dialed-in rifle and I didn't even bother shooting the last five out of the box. It was that bad.
The 180gr. ammunition was Winchester SuperX soft tip (180gr. as previously mentioned). I want to say the box was around $30 at Bass Pro. POF doesn't recommend soft tip ammo but I thought I'd at least try it as it was "on the shelf" and I wanted to see how it handled heavier bullets.
Anyway, my enabling neighbor, who is an experienced, scientifically driven reloader, wanted to dissect the last five rounds. "Go for it" I said and gave him the remainder of the box. After checking every measurable parameter including grains of powder, he decided to cut the bullets themselves length-wise. And there it was. Voids in the lead core. That'll do it at 120,000rpm. So don't always blame the gun, buy (or produce) better ammo. Internet confirmation bias is a b*tch. Lesson learned.
