Uh, one thing I didn't see mentioned is that when working up a load, you should start at ~10% max & without changing anything else, change your powder weight .5 grains.

May be mistaken, but appears that you're missing the boat by just loading up X grs with one bullet & X grs for another. It should get quite a bit more in depth than that to really squeeze out your rifle's best performance.

Fer instance (& don't take this literally one bit) using an 87 gr bullet, start with three rounds @ ~35 grs IMR 4895, next is three rounds with 35.5 grs, then 36.0 grs, etc. to max (& quite frankly) I'll usually go as much as 2 grains over max. If I start to see pressure signs, I don't shoot the heavier charge & just pull 'em when I get home.

I'd not suggest just loading up one combo, going to the range & settling for whatcha got - the best between the two. That's the whole beauty of working up loads.
