Those velocities are realistic with my 115 gr FN with gas check, but cases will stretch exactly the amount of headspace when running high pressure loads. That can mean extremely short case life. Three shots with my marlin before I tightened the headspace to a light touch on the ctg rim, then I could load one case hot for 50 rounds with no change in the case.
If your bore is cloudy or pitted don't even look at plainbase bullets. and plan on lapping it with the LBT lap kit. For just small game use, with velocities to 1600 fps or maybe a bit higher, plainbase will work fine and make shooting a lot cheaper, if the barrel is real smooth.
