Do you think using an ar15 is good for deer hunting? .223/5.56 or 6.8?

6.8 SPC? With out question.
.223 loaded with the right projectile? Also a yes.

There are several manufacturer options out there. Federal loads 55gr SGK's, 55gr Barnes TSX's and 60gr Nosler Partitions, all of which will flat stone any Texas White tail inside 150yds.


Chupa

Give me a choice and I will take the 6.8 for hunting every time even though I dont have one.

Yup, 6.8 would be my choice.

My .308 works great.

Couldnt have said it better!!! Wise advise.

.223 is pretty dang good flat out right placed shot you can do anything with it

I just got my custom built 6.8 upper in last week and I have every intention of taking a deer with it this coming season. 110 gr Accubonds will do the trick I'm thinking or the 110 gr sierra pro hunters.

Sweet build

Thanks, it will be sweeter when I replace that rattling M4 stock!!

NICE

I hear ya, I have been lazy lately because I have not had but one chance to get to the lease, but I plan on getting a magpul ubr on mine this week. What are you getting Mike?

I have a DPMS pardus on mine, yes I know Im cheap but it doesn't rattle too horribly compared to some of my old AK-47 magazines or some of my old cheapo sling swivels

I used my AR this past deer season. I didn't take a deer, it was a crappy season up in Wisconsin, warm and wet. I saw 5 does the entire gun season.

But we did test some ammo and the Federal Vita-shock 60 grain nosler partition was very good. From my gun blind a long range shot is about 80m, and the 2 deer I have taken from it were 50m and 60m. With decent shot placement at that range I felt very comfortable trying to take a deer with a 5.56mm even after some heated discussions in the cabin.

With all that said I plan on going back to a .308 this year, just to keep the peace at the cabin.

Most likely I'll be getting a Vltor IMOD folks that have them rave about positive cheek weld that they get with them and say they lock up tight at each position.

going with a ubr myself and then I think I am done with my rifle! until I decide I need another one that is!

I don't think that they are ever actually done.

Winchester silver ballistic tips work great on texas deer never had one run more than 5 yards then pile up.

22 Hornet works too
