In the past, Sierra 50 gr. Blitz and/or 52 gr. HPBT Match (and 55 Hornady SP's) were my go-to's for .222, .223,, R2 Lovell, and .22 Maximum Lovell - all in the low 3000's fps. I'm currently enamored of another one - the Berger 40gr.flat base varmint/target. That little bugger sizzles out of the barrel of my 26" .223 Browning Low Wall at nearly 3600 fps and prints boringly repeatable sub-1/2MOA groups at 100 and 200 yards. I can't attest to how well it carries out beyond that as our suburban Maryland range doesn't extend past 200, nor have I shot any creatures big or small with it, but I should imagine it would be effective on small ones given the bullet's construction and velocity.
