Great advice in a nutshell right there!It’s not a matter of bullet weight. What you need to look for is any bullets minimum expansion velocity. Then with the bullets bc and muzzle velocity you can use a ballistics calculator to find at what range it drops below that minimum velocity.
Hornday has a free ballistic calculator on-line as do a number of others. The bullet mfgs publish their bc's. Note that there are G1 and G7 bc's. Either will work but make sure you have the calculator set for the one you use. The heavier for caliber bullets are longer and have higher bc's in any bullet design. You should see a positive effect of the higher bc at about 400 yds. Hornady bullets are not my favorite, but they are are good and seem to be the most available right now.
