55s will work find in your 1:7 twist. In fact I have a report where the Army was checking the accuracy of Lake City's Mann device (Mann accuracy device is used to test ammo).

They used Sierra 52 grn Match Kings (with 25 Grns of 3031 in remington Brass and fed primers). They ended up with groups from .19 to .31 Mean Radius.

You can also go to 80-90 grn pills for long range shooting.

Hornady 52/53 grn match bullets are normally found for good prices. I use them for 100 yard reduced practice. I use 77 & 80 SMKs for 200, 300, 600 & 1000 in my 1:7 White Oak Service rifle.

If you're just plinking then you can find 55 grns bulk bullets that work pretty good. I shoot them out of my Colt SP1. (1:12 twist.
