I always get concerned when a manufacture drops an old line of bullets because I have invested time and components in load development of safe loads in my rifles. I am fortunate in the case of Speer that I have a fair supply of the bullets I use which focuses around the 7MM Remington Magnum. The center of my 7MM world is the Speer 160-grain Spitzer. It is an accurate, long range bullet in my rifle.
A trade with my brother sent some 150-grain WW bullets to him for his 7MM-08 and in turn I got some sealed boxes of 160 and 145 grain Speer bullets from him. The 145-grain bullet will be my choice if I make a speed goat hunt. A good bullet for light framed, adrenaline charge game. Did a little trading with Gunner Runner last week and it filled out a box of 145 grain Speer bullets.
If change keeps them in business I am for it.
