which cartridge has better trajectory and less wind drift at 350 yrds
I ran some numbers a while ago with pointblank to calculate wind drift of various PD loads at 400 yards. Here are the results:
Bullet Weight/Type BC Cartridge Name Velocity 400 yd 10 MPH wind Drift
39gr Sierra Blitzking 0.287 .204 Ruger 3750 11.5"
40gr Hornady Vmax 0.275 .204 Ruger 3900 11.5"
40gr Nosler BT 0.239 .204 Ruger 3750 14.3"
40gr Sierra Blitzking 0.196 .223 Rem 3700 18.6"
40gr Hornady Vmax 0.200 .223 Rem 3700 18.2"
40gr Nosler BT 0.221 .223 Rem 3700 16.0"
40gr Sierra Blitzking 0.196 .220 Swift 4250 15.6"
40gr Hornady Vmax 0.200 .220 Swift 4250 15.2"
40gr Nosler BT 0.221 .220 Swift 4250 13.5"
40gr Sierra Blitzking 0.196 .22-250 Rem 4150 16.1"
40gr Nosler BT 0.221 .22-250 Rem 4150 13.9"
40gr Hornady Vmax 0.200 .22-250 Rem 4150 15.7"
55gr Sierra Blitzking 0.237 .22-250 Rem 3680 14.8"
55gr Nosler BT 0.267 .22-250 Rem 3680 12.8"
As you can see, the .204 really shines (the 3900 fps 40 gr vmax is from the Hornady factor ammo).
