I did a little research.....
The 22-250 w/ a 50gr V-Max at 3300fps (conservative load) drifts 19.1" at 400yds.
The .204 w/ a 40gr V-Max at 3200fps (conservative load) drifts 17.1" at 400yds.
Max rifle velocities for the 22-250 are in the 3750-3900fps range for this bullet. My load is at 3300fps...I based the loss of 450-600fps against the .204 for its velocity. Hodgdons website shows max velocities of 3600-3700fps...so I used 3200fps as a conservative figure. I was surpised to see that little 40gr .204 cal V-Max sports a BC of .275.
Thanks Dan. I had read some articles that were giving the .204 around 4200 fps with 40 gr V-Max's. I was thinking that with that kind of speed, air time would be minimized. You folks have the experience though so I am more apt to trust what you are telling me (plus you back up what you say with the "bible").
Decisions, decisions, what to do, what to do..... hummm
