I think I've gone crazy.

So the first time I tried loading 60gr partitions for my 22-250 they tumbled at 30 yards. No that surprising since I'm shooting a remington. I have about 10 left though so I'd thought I'd try it one more time just for kicks. Today, at 50 yards all six gave perfect entry holes (and from what I could see on the backside of the tree, perfect exits) Same case, primer, powder...same procedure. The differences are the 95+ degree weather and due to that I took my load down to 32 and 33gr of IMR4320. (I was running right around 34-36gr if I remember correctly, cant be sure 'cause I threw all the notes away after giving up.)

Would pushing them slower help stabilize? My logic says the opposite...but my logic has been known to suck.

vey possibly.

if they're being pushed too fast for the twist rate, yeah, they'll tumble and keyhole and do all kinds of rude and disgusting things.

I agree with your logic-moving faster should increase stability, IF a slow twist is causing your problem! (I never could get the .22/250 I had to shoot well with those Nosler 60-grain bullets. Mine had a 1/14" twist. But it never occurred to me to try REDUCING the velocity. Maybe you've stumbled onto something here!)

BUT, based on what you have learned, you do need to load up some more of those 60-grain bullets with the powder chargethat shot well, and continue testing!

If it turns out that the lighter load shoots better, use it!

I just hate it when I can't explain something...but now I definately have to go buy another box of the NPs. (Hopefully they'll have some barnes as well.) But how I HATE spending upwards of 2 quarters for a single .224 bullet!

If you are pushing them fast enough that the copper is being ripped off in the barrel, it would cause them to do what you are describing.
