Is 110grain cartidges enough to bring down a deer, i mean do they have enough power?

Sure, what kind of rifle do you have? My grandsons use a .243 with 100 grain Hornady bullets. Shot placement is the key to harvesting your deer. IMHO it is best to stick with a good bonded bullet, I do not like a ballistic tip.

its a 30 carbine

I think we had this discussion already didn't we? With the 30 carbine I would pickthe heaviest bullet you can find, and get one made to hunt with, like a hollow point or controled expansion type bullet. Not a military surplus or full metal jacket round.

What bullet specifically are you thinking of using? Like the brand and model.

Where I hunt is pretty brushy and a 100 gr would not cut thru some of the stuff I have to shoot thru. Any reason you would not shoot a larger round?? Shot plcement is important but if you do not hit that "sweet" spot then you have just injured a deer and will never find it till the coyotes do.

I do shoot a 30-06 but found my grandpas 30 carbine and thought that if it would work for deer then i wouldn't need to buy another rifle.

And yes, we did have a discussion (quite a few if im not mistaken) about the 30 carbine. But im pretty sure that the grain was not mentioned and so i was curious if 110 grains would do the job.

From what I can see the 110 grn is about the only one available. At least it's the most common. Just get the hollow point.

If I had to choose between the carbine and the -06 it would be the -06 hands down.

Of course if you are looking for more of challenge then using the carbine at pistol or shotgun distances should work well.

I think test have shown that hunting rounds will not "cut thru" undergrowth effectively.
