300-221 (Whisper) reloading data needed

[kurtz]

I have used 2230, but it is pretty slow for the amount of powder, even out of a 20" barrel....
Standard disclaimer: wildcat reloading data use at own risk
A comparison load:

125 TNT 22gr 2230 = 2,250fps (bullet set out in neck and compressed load)
125 TNT 18gr H110 = 2,375fps (magnum pistol powder)

Hope this helps....


If this is screwed up it was sent from a Blackberry "Bold"
