case sizes and amount of powder to push a 30 at 3800

[skb2706]

.204 Ruger does this with ease.
32 gr. Hornady Vmax
29.0 gr. RL-15
BR-4 primer

4100 fps .......all day

If all ya wanted was 3800 back it off a few grains.

My .221 will probably make the critieria although most .224" bullets at 30 gr. have pretty crappy BCs. Thus they tend to fly like a single bed mattress.
