I load a lot of light weight varmit bullets for my 270's and 7mm RM mag.s and have always been amazed at the incredible accuracy these light fast flyers are. The other day I took several boxes of 100 gr. Sierra'a and 110 Gr. Speer TNT's to the range. These puppies were loaded with RL22 just a bit over mid rane data. The Sierra 100 grainer's were doing aorund 3400 fps and some change and grouped from .620" - the .700' ish on the wider end at 200 yds. The 110 gr. Speer TNT was in the upper 3300 fps range and was printing just around .500" - .665" range.
One thing I've noticed over the years of loading light weight varmit bullets for the .270 and 7mm RM is when I drop my load down to below mid range the groups open up and produce serious flyer's @ 200 yds., some even 3" - 4" outside the primary group. I also think that shooting lighter bullets has an effect on how well I'm shooting, I think this is due much to the reduced recoil in comparison to the heavier 140-145 gr. bullets.
The 90 gr. Sierra's for the .270 are in the 3700 fps range, and still hold tight .500"-.650" groups. All the years I've been loading hot light bullets I keep hearing how poor my accuracy must be at those velocities, but even I've been surprised in this way.
