RE: 30.06 USERs
Make sure you check your regulations as full metal jacket bullets are illegal in most states.
I prefer the Remington Core-Lock in 165 grain bullets. That is what my rifle really liked and produced the best results with.
I suggest that you buy a box of 4-6 different brands and grain bullets to see what shoots out of your rifle the best. Some rifles are very particular and will only shoot a good grouping with 165 grains (this was the case with my old deer rifle). Some rifles will shoot good groupings with all bullets, it is just a test to see which one your particular rifle likes.
If you post the brand and model rifle that you will be using there is bound to be someone here that shoots the same and they will usually give you a bullet recommendation for it.
Good luck!
