highest BC bullet for 1/9 R15

[mr.big]

thinking about putting the 4.5-14 I got from ewc on my R15 and loading the slipperiest bullets that a 9 twist will take.

I dont care if I have to single load or not,,just want to fool around and see what the 223 is capable of at say 500 yards.

is the 75 amax top dog,,77 SMK,70-80 berger,,what is the highest BC bullet that will work with a 9 twist 18 inch bbl??

I want to get used to spinning the knobs on this scope is really what I am after before I move it to something that costs a fortune to shoot.

a .435 or so BC or better would be nice and maybe 26-2700 fps,at 4-500 yards should get a crash course in knob spinning.

I am shooting the 70gr Bergers out of my SPS Tactical. I am able to average .5" MOA regularly at 200 yds. I need to find me somewhere too stretch it out farther.

There is a good stability calculator on JBM Ballistics website that should help you decide what will work.

The 70gr bergers can be loaded to fit the magazine. My gun has an 1/8 twist but I know 3 or 4 others who have tried them in 1/9 barrels and they shot well.
