Which is a good twist to go with for a 16" 223 for a plinking gun using 50-62 gr bullets. 1/7 rate 1/8 rate 1/9 rate
For that range, 1x9 is fine. Usually cheaper and more available. 1x8 would let you go a little heavier if you wanted, but 1x9 will usually shoot the 69gr hollow point / match type rounds, so you're not sacrificing much unless you want to shoot the heavies.
If you are planning to shoot from magazine - 1:9 will do great.
All 3 will work for those bullet weights. The 1/8 and 1/7 will just give you more options as far as heavier bullets if you ever want to use them.
Anything 62gr and under will stabilize just fine with a 1:9 twist rate.
The higher twist rate just gives you options to go with longer heavier bullets.
If you are considering using it as a go to gun with something like the 75gr Hornady TAP rounds then get the 1:8 or 1:7 twist rate.

I believe 75gn Hornady bullet was specifically designed to work in 1-9 twist. There are mixed reports though....
Buy whatever is a good value and don't worry too much about twist. I was very picky when I built mine and refused to buy a 1:9 because I bought into the hype. I'm not willing to pay for ammo what the heavies cost so I could have saved money and gotten a 1:9 twist. In most of the weights available 1:9 is fine. You have to go looking pretty hard and be willing to spend more money than you need to to find ammo too heavy for the 1:9.
1-8 or 1-7. You can shoot all the bullets with either and give nothing up to 1-9.
