I have not hunted with a 223.
But my brother has killed more deer in the last 3 years with 55 grain z max that I loaded.

Per Sierra. Their 60gr hp (designed for 220 swift, 22-250 velocities) has worked well on deer out of 223 with velocities kept between 2800-3000fps. I’m going to give those a try because my rifle has a 12” twist. If it had a faster twist, I would use the 65gr Sierra gameking.

Could be wrong,but I would be surprised if the 12 twist would shoot the 60gr bullets accurately.
Are those bullets a flat base ?? What rifle do you have that has a 12 twist bbl ?? --- SAWMAN
Amazing . . great to hear. The longer barrel guns ??
Gotta give them a try in my 11",1:12 twist XM177E2. Been looking for a "just in case" hunting load.
It will not shoot the M855 green tips. Not enough lead I suspect,+ the length,being a boat tail. --- SAWMAN
Didn’t specify barrel length, just 2800-3000fps. I guess if you can attain 2800 (or close) from an 11” barrel, you should be good to go. I have never tried them, so all of this info is from Sierra, but I do have a partial box on hand that I am at least going to try to work up a load.

I was watching a video on you tube. This guy was shooting the 55gr hornady sp w/ cannelure into 10% ballistic gel. First picture shows 3000fps impact velocity. Second picture is 2750fps impact velocity. Very interesting results. https://uploads.tapatalk-cdn.com/201...5947839277.jpghttps://uploads.tapatalk-cdn.com/201...f200359a0f.jpg

That’s interesting on the difference in penetration and weight retention.
