im doing a project for one of my classes and my topic is "does increased speed lead to improved accuracy?"
my plan will be to lad a variety of loads for my .30-06 and then go park it on a bench rest with a chrono and shoot 3-3shot groups at 50 yards and then take the average size of them
ill record the size charge and speed for the load and the group.
but i need some fairly cheap projectiles since i wont be using them for meat or for long distance. id like something 160gr+ since my rifle doesnt shoot the 150's well
anyone got a lead on some?

I see several flies in the ointment here.
First, most cheap bullets are military pulls, and are not going to be accurate enough to provide any meaningful data.
Second, 160 grain+ .30 cal bullets don't really settle down and fly right until they are well past 50 yards.
Third, about all your test will prove is that every rifle has several sweet spots for a given bullet & varying powder charge.
You might get great accuracy at 2,100 FPS, go through a period where barrel harmonics throw off shots at 2,300, and then come back to another sweet spot at 2,500, bad at 2,600, and great again at 2,750.
So, does that prove anything concerning "does increased speed lead to improved accuracy?"
I think not.

These are pretty cheap. http://www.wideners.com/itemview.cfm?startrow=13&dir=278|281|727
Don't know what to expect in the way of accuracy, though.

you can try these also the 150 grain are pretty good
