Sighting rifle with Hornaday 165g SSTLM

[rio]

If I sight my rifle in with Hornaday 165g SSTLM and then switch to a different ammo, maybe a 150 grain bullet, will I need to adjust the scope radically or can I consider the gun already sighted in? Any opinions

You will need to re-zero. Will prob hit close so that ajustments might be small.

Or they might not be.I have seen differences of over 3" in point of impact at 100 yards.

Never take anything for granted, you may or may not have to adjust the scope but you have to take it to the range and prove it to yourself.

You may be lucky and it will be close,but chances are it will be off,up,down,left or right.Amazing the differences sometimes.Always best to check!!

All the above are right advice. Good going, guys!
