Just out of curiosity I looked on YouTube today for 223 bullet reviews there is a guy on there that puts the mentioned bullets through the gell stuff.I found it very informatble. Mite want to check it out.

FurFlyn I hope my son and a lot more young uns change history next weekend. Lol!!!!!!!

doesnt the twist have something to do with performance and bullet weight. Heavier rounds need the faster twist like 1:7. Any info would be appreciated and would probably benefit other folks as well.

Well, I believe you are right. Heavier bullets generally need a faster twist to stabilize. My rifle has a 1:9. I shoot 55gr bullets, and they group about 1.5".

Idk at what range a slow twist barrel is going to let a heavier (over 70grn) bullet loose stability. Somebody with more knowledge than me can weigh in on that, but at 223 ranges for deer, I doubt its going to make as much difference.

I'd like to keep 223 shots well within 100 yards.

Twist is very important for stability. A 70 gr Barnes X is longer than a 80 gr Seirra Match King. A 62 gr Barnes X will stabilize in a 1-8 BUT not a 1-9 . OR Its might I would say 95 % of your Ars with 1-9 Twist will stabilize a 62 gr Barnes X . THats a good deer bullets for a youth

Does the 1:7 limit me on the lighter 55graim ammo

No. I have seen where - on my Noveske that a 1-7 twist would fire 77 smks in to 1/2 MOA at 300 yards. When i shots some 55 gr FMJs sighted in same dead on at 50 yards . They when right. I mean the hole group zero wind still 1/2 MOA or so at 300 yards BUT went right. Brian Litz gives a technical reason about Over Stabilization at Longrange. but with 1-7 and 55s you want notice it till 300 yards. At 500 it was only about 3 inchs left with 40 gr V-maxs. So you can shoot 40gr bullets BUT grouping my very from gun to gun with 1-7 twist

Cool, after reading into twist vs bullet weight I read that when 223 was first used by military they were using like a 1:12 or 1:14 and that's what caused the bullet to tumble on impact, but now most folks believe that all 223's still tumble, but said military changed its theory and wanted more penetration in order to possible cause multiple casualties per round due to pass throughs

I know a guy that absolutely believes that every 223 bullet tumbles in flight. I even took a cardboard target to show him and he still didn't believe they didn't tumble. Some folks just flat out refuse not to be ignorant.

No matter the caliber, always behind the shoulder.

I think it's mainly the 55gr bullets AFTER they hit a fluid medium.

Shooters, have you ever seen a heavy bullet from a 1:9 barrel destabilize inside 100 yards?

Yes. A friend of ours in Ms that we hog hunt with has a SBR. It started its life as a pistol. 1-9 twist 8 inch 223 with 77 SMK shot about 4 -5 inch groups at 50 yards. IF you looked close enough you could see the NOT so round hole the bullets left. I bet at 100 it would tumble. So he ended up shooting 62 gr bullets. Same would be true I guess with a 1-9 and a reduced OR subsonic load and a short barrel. So lots of time its speed = Or lack of speed that could make 1 gun stabilize = and one not. Like I said before a 70 Barnes X is longer than a 80 SMK. So its possible

We killed hundreds in the past. There were several of us who used .223's back several years ago. My wife and both kids killed their first deer with .223's. We prob killed more with 55 gr psp than anything. All were behind the shoulder shots, most didn't make it 75 yard. We usually fond the bullet in the off-side shoulder in the hide. Shot placement is the key. It is a very good caliber for new hunters, no recoil and it doesn't scare kids. Keep the shoots to close range and behind the shoulder and everything should be fine. I do like the Barnes X bullets. I shot a few be bucks through both front shoulders. They didn't go far and the bullet went all the way through with the Barnes X. That was when I was doing a lot of reloading. Good luck.
