If any of you have ready my replies to PD bullets you have likely noticed that I am a proponent of the 40 gr bullets for PD shooting - here is the reason I favor the 40 gr over the 50/53 gr bullets.
Below are the JBM ballistic charts comparing them - it is obvious that the 40 gr does not give up anything significant to the 53 and in most instances the 40 gr bests the 53
3700 fps out of the 223 with 40 gr is obtainable with numerous powders.
3000 fps out of the 223 with 50/53 gr bullets is the top velocity with most powders only attaining 2850 - 2900 fps.
These are not "pie in the sky" figures - the 3700 and 3000 fps are from load data from reloading manuals. These calculations are top velocity with both bullets.
The 40 gr Nosler has less drop, drift figures are essentially comparble, energy figures favor the 40 gr out to 300 yds and then slightly shifts in favor of the 53 gr but so little as to be insignificant.
Recoil differences between the 40 and 53 is negligible but is slightly in favor of the 40 which may make a difference on a high volume day.

53 gr Hornady V-Max @ 3000 fps - 10 mph wind
