I have a PTR91F. I also handload.
When i first started handloading, i made up a batch using some 150gr softpoints that a friend of mine had laying around, just to function test and form a baseline.
At the range, they functioned fine, but at 100 yards i got a very curious group...actually 2 groups, about 2 inches apart. Couldn't figure out why, until i chambered a round, then had to unchamber it (i dont recall why). I inspected the ejected round, and discovered a large flat spot on the side of the soft point where the tip had just grazed across the corner of the square breach face as it chambered, skiving a flat into the lead. I suspect it disrupted the balance and aerodynamics of the round enough to induce a spiral yaw and, depending on whether it fed from the left or right column, impact off center.
BTHPs stil showed slight damage to the tip from feeding, though significantly less than soft lead, and didn't exhibit the splitting group the JSPs had.
With this info in mind, i picked up some polymer-tipped rounds to try, reasoning that the tips would be more resilient during feeding, and therefore potentially more accurate. I loaded a dummy round and fed it through the action several times, and found no damage to the bullet tip.
So, ultimately i worked up a load with Hornady 165 SST's at 2500fps that gives me 1-1.5moa groups on average, while being an expanding hunting bullet that costs slightly less than 168 SMKs.
