I have my Marlin 30/30 model 30as sighted in for 50 yards with 150 gr bullets. Yesterday, I just picked up a box of Hornady LeverEvolution bullets that are 160 gr. What the zero be different if I used the Hornady 160 gr bullets for deer hunting? I'm going tomorrow so there's no chance to sight it in for 160gr... would my scope still be effective to make an accurate shot with the 160 grs even tho it's sighted in for 150 grs?

unfortunatley, yes it will be a different point of impact. The lever everlution ammo is straighter shooting and carries farther anyway. I would hate to see a wounded animal suffering because of a poorly placed shot. Even though the lever evolution is the better round, I would suggest that you either use the same ammo you sighted with, stop and re site the weapon, or skip the hunt. Don't let the animal suffer because of your lack of preparedness. And I don't mean that as an insult, just that you should not have waited to the last minute to change ammo, and not allowed time to re sight.

The LeverEvolution bullets have a significantly different ballistic coeffecient than the ammo that you sighted in with. I don 't know what the muzzle velocity with either round is but in addition to the different BC, a different MV will add up to a significant difference in POI at distances beyond possibly 75 yards. Out to there, your POI should stay within the kill zone for a deer. A .30-30 is usually not good for shots beyond about 150 yards but people are trying to make longer shots with the LeverEvolution ammo. If your gun is sighted in for LeverEvolution ammo, you might be able to make the longer shots but you would have to be zeroed with that ammo. If you have the discipline to keep your shots under about 75 yards, you will probably be okay with the change of ammo. Beyond about 75 yards it will most likely be a crap shoot and not a shot that a responsible and ethical hunter would be willing to try. Can you pass up a nice deer that is standing broad side to you at 100 yards? If not, you had better sight in with the LeverEvolution ammo before going hunting.

It might not be just a matter of up or down a bit. I have seen some ammo actually change the sight/hit point to the right or left. Not often but I have seen it. If you have any of the old ammo left use it or don't shoot more than maybe 50 yards. I had a .22 that with Xpediters the shots shifted over 3" to the 8 oclock position at 50 yards! Not the 12 or 6 oclock I was expecting going to a faster shell! I had to sight in again for that ammo for hunting!

When I sighted in my Marlin 30-30 with the LeverEvolution the zero was different than the other bullets I was shooting . I would wait to use the LeverEvolution after I sighted them in .

Take off the scope, use the sights, place your shot on the shoulder within 50 yards, and don't worry about a 10-grain difference in bullet weight. The deer won't know the difference. He won't go anywhere either.

at 50yd. there wont be enough difference to matter but they will probably shoot a little high at a hundred & beyond as their a little higher velocity than regular 150 gr. (2400fps)30-30s & the pointed tip gives them a better b.c.than a flat point.
any time you change ammo you need to check your zero as its pretty common to get a different point of impact with different brands.
the mossburg 30-30 I tried them in didnt like them at all & didnt group well with them(it likes 170s better) but they may do fine in yours.
anyway you need to see where they hit from your gun before you try any long shots.I wouldnt worry about it at 50 yds. though.

At 50 meters a 10 grain difference will not matter at all.... If you were sighted in at 300 meters it might make a slight difference, but dont worry about the 10 grain difference you have.

Even changing to a different batch of the same load you've been using can affect zero, and one 150 grain bullet won't shoot the same as another, so there's no way to tell where it'll shoot. It probably won't be a foot off, but you'll want to shoot the new load as soon as you can.

ya it will be fine unless you shooting more than say 70 yards but thats a long shot for a .30-30
