a 250 SST will retain better ballistics than a 300 XTP [with inferior BC]. Not all heavier projectiles have better BCs. That XTP bleeds fast.
An example would be say a 30-06 165 BT vs a 30-06 180 RN.......the 165 is going to shoot flatter and retain more Ftlbs. So not all heavier projectiles are better.

sure, but if you compare the same bullets, the heavier one wins..

a 300 grain sst will perform better downrange than a 250 grain, generally speaking.

is either more ft lbs....or flatter trajectory! take your pick. Unless you consider a Barnes copper, which one can shoot lighter weight but drive faster and still get the penetration. The best of both worlds.

i'm not worried about ft lbs or trajectory.

if the bullet is designed well - 250 or 300 grains is going to get the job done in the energy department.

and again, imo, trajectory is very predictable. if you know your distances ahead of time (with a rangefinder and landmarks) then trajectory is a non-issue.

And, Im only using a piddly .45 cal Optima with 200 gr SSTs. As we all know, deer are very easy to kill.
