Are there any 175gr rounds designed for 1:12 twist?

I shot some 168 gr MK out of my 1:12 Remy and got 0.5 MOA. Firing some M118 ( 175gr ) got me 3 MOA. I've heard of people shooting under 1 MOA with 175gr.. but before I start experimenting with loads.... do you have any idea what bullets might be designed towards a 1:12 twist at standard velocity?
