the back ground is that i have been shooting 110gr Barnes TTSX fedreal factory rounds (for 7mm rem mag) and am very happy with accurcy bullet drop at distance and stoping power/meat damge. i have now been infromed that the round is no longer getting made and Barnes have removed the load from there website. i have a friend who can hand load rounds for me but i have a few questions.
The basic question is. What is the lightest 7mm bullets heads i can buy?
The second question is for any1 shooting a 7mm mag or any other high velocity round. Do i need to used bonded cores or simalir when the velocity is greater than 3500 fps at the muzzle? (tested 110gr factory at just over 3600 fps)
