WHAT AMMO IS THE MOST ACCURATE IN MY RIFLE?
Not to be cheeky, but the answer is "it depends". Are you looking for a hyper-accurate round, or just something off the shelf that shoots well? People's definition of "accurate" varies quite a bit. Some people would call a 1.5" round at 100 yards accurate, while others wouldn't be happy with anything larger than 0.5" at the same distance. To obtain the absolute best in accuracy, you'll have to try it in your rifle and experiment. If you're just interested in some loads that others have been happy with, then here's some recommendations. The list is not all-inclusive by any stretch of the imagination, but should give you a starting point:
As you can see, there are a lot of different ammo types that people have good results with. To reiterate: To find the absolute best, you have to experiment to find out what works best for you. If you're a reloader, you should already know that. One additional note: While 1:9 barrels usually can shoot 75gr bullets, they're only marginally stable and you will probably find that they won't shoot very accurately out of these barrels.
Arfcom user Cody47 has done a great job shooting 5-shot groups of a bunch of different ammo and posted the results. This ought to give you some more data to ponder:
