I guess it kinda depends on who you ask each person has their prefrences as do the guns. I have tried several out of my old model 94. I prefer Remington Core-lokts in 170 grain, my gun doesnt shoot very well with 150's or winchester ammo. Most 30-30 ammo is very very affordable compared to other rifle rounds. I pay like 7 or 8 dollars a box for my Remingtons. If you can find them another round you may want to try is the 30-30 starfires which are loaded with Barnes X-bullet, full copper rounds. I think some compaines even offer premium rounds in the 30, bullets like partitions. Since most 30-30 rounds are around or under 10 dollars a box the best advice i can give is get several and see which one shoots best out of your gun. I have taken several deer with mine with the 170 core-lokts, it really does the job.
