They make all these claims on the fact that berger makes a 180gr .284 bullet with superman BC's.
1. Is there a trade off point with the 300Win Mag where heavier bullet( Higher BC) starts to loose out to loss in initial velocity? I.E. 180gr traveling at 3100fps vs. 210gr at 2850fps.
2. Using the above logic couldn't all cartridges be compared on their "absolute best" combination of Highest BC bullet and velocity combo for longest range performance?
Possibly set a score system to find the distance at which terminal energy drops below 1000 ft-lbs as a universal end point?
Does this make any sense?
Most of the realy long range guys are turrent twisters and look for maximum down range
energy and accuracy.
Velocity and trajactory does play a part but in the end they chose energy at POI, wind bucking
ability and accuracy at longest yardages to be hunted.
I don't have the skills or the equiptment to ''HUNT'' much past 1500yrds so I use the ''Taylor
Knock Out Value '' system for the best results.==1000 ft/lbs for deer size game and 1500ft/lbs
for elk size game. with these numbers you can add or subtract based on the game to be
hunted (IE, Moose would require 2000 ft/lbs)for clean one shot kills.
You can kill all game with less energy but the results will vary more from shot to shot.
Armed with this information use ballistic charts that will go past your intended distance and
look at max distance to reach energy levels required for the game to be hunted and which
caliber and bullet combo is the best.
In other words if I go elk hunting and have a choice of rifles that will take an elk down hard
I would chose any 338 my next choice would be one of the big 30s and next would be a
You can never have to much rifle only to little.
This process will separate the groupies from the rock stars.
Just the way I approach this decision.
