I have a 260, a 6.5 creed, and a 7-08. They all kill whitetail deer efficiently. I cant tell the difference between them from the stand point of dropping a deer. They all have threaded barrels. And with a muzzle brake on either one of them it cuts the recoil almost in half. I have 4 grandkids. They range from 4 to 9 years old. My grand daughter will be the first up to go deer hunting next season. so far she has been doing really well with her .22. But when she steps up to a hi powered rifle it will have a muzzle brake on it. Once she is comfortable with it and shooting it well we will try it without the brake. I think they are less likely to develop a flinch this way. I do not reload any more so this is another way of taming down the recoil.
