I have two Glocks in 40 S&W and I am in the process of buying a Delta elite in 10mm. I generally use 155 and 165 grain bullets in the 40's but I am wondering which bullet I should buy for the 10MM, that will give me optimal energy and precision, that will also work in the 40. My Glocks are not target guns or "game getters", they are strictly for self defense. The Delta, on the other hand, should be pretty accurate and able to pack enough wallop to take down a good sized hog or deer. I am thinking that bigger is better for the 10MM but maybe the 165 would be just fine. By the way, while I will probably find a FMJ for practice I am wanting a Hollow point for most purposes, so what weight bullets should I be looking at.
