You can easily push gas checked boolits north of 2000 fps without leading issues. I currently load a 130 grain .285 bullet in my 7mm-08 at about 2150 and no leading issues and it will shoot 1.5MOA. I have a 206 grain gas checked that I shoot out of a CVA 35 remington right at 2050 and it shoots great also. Been shooting a factory gas checked 185 grain .358 out of my Marlin 1894CP at about 1600 for years and no leading there.
However, I do believe non-gas checked boolits forces you to stay a few hundred feet slower, but I couldn't give you exact numbers. I am sure it depends on the alloy and the caliber as well. Powder coating lets you go a bit faster than lubing also.
