I would look into the lines of both aguila, and cci. Aguila makes a high velocity round, in both hollow and solid, that are damn accurate. Aguila is made by/with eley products, so you know they are good. I would avoid hypervelocity, such as stingers or velocitors, if velocitors are based on the stinger case. these are notorious for battering semi auto actions to bits; so personally I would avoid them. Also a very good round, that is cheap and surprisingly accurate , is american eagles, red box, made by federal.
lemme show you these three;
golden eagle is an american made eley product as well...
these were all done, by a mod 60 with a 24x scope, at 100 yds,
sandbag rests only.
the 60 grain aguilas, if they work in your action, and they may not, can be
exceptionally accurate, or keyhole about 20 yards after leaving your bbl; you will
just have to see.
