I am not agruing anything but most hunters don't need this fast twist long bullet stuff.If you are shooting ultra long range, ok, but most hunters don't need this for their hunting. Range finders, turrets, excellent. But how many folks in the field use them or even need them. They are great, but to the point is most game is taken at less than 500 yards. So fast twist is unimportant. Up to 500 I can do all I want with what I have. I have turrets, range finders I enjoy them. If all works out, the range finders are a great aid in determining exactly the range once I know that I am set. Anymore I don't shoot most game over 400 for a number of reasons. If this fast twist makes you happy fine, I tried it. But for hunting an most shooting it is not that important.
if you use Hammer bullets and some other brand bullets you better know the twist of your rifle barrel if you plan on using these types of bullets some Hammer bullets and others need a fast twist some not so much. but if you don`t shoot or reload much you probably will not ever know the difference. as has been posted already your keyboard or reloading ballistics in a reloading book won`t steer the bullet for you.
