Hello can anyone tell me the best bullet wieght for a 223 with a 1&10 twist barrel
Thanks

Whatever brand of 55gr. bullet that turns you on. The one in 10 will stablize heavier bullets but the 55s give you a wide choice and will do the job. roger

Now that Roger has provided a technical answer I'll take a stab at a philosophical one....

What are you doing with your 1:10" 223Rem rifle?

Some guys doing serious target work swear by the heavier low drag bullets.
Others (who work for the Army) THINK that longer heavier bullets can turn the 223Rem ito an anti-personel round that it has never been and will never be.

Still others want to emulate the army ballisticians.

That being said for varmint work heavier bullets aren't going to turn the 223Rem into a "long range cartridge"
or any other such rot.

For varmint work inside of 300, 325 or mabey 350yards the only thing better than light bullets driven as fast as possible are lighter bullets driven even faster.

My personal choice is if I want to toss a 70gr bullet I'll use a 6mmRem to throw it., yeah a low drag 69gr .224 bullet has a great ballistic coefficient but in what alternate universe is it equal to the near identical ballistic Coefficient of a 70gr 6mm bullet launched >700fps faster?

A .223 is a .223 all the time.....whether the twist is 1-14" or 1-9".......
Your 1-10" will handle 35 grains to 60 grains with ease.

My .223 rifles have 1-14" and 1-12" and the bullets that make them sing are the 40 and 50 grain bullets. While one might shoot the heavier bullets IMO the .223 is made for the 40-50 grainers and if you want to shoot more than 55 gtains you probably want a .22-250 or a Swift!

Since for some weird-assed reason, I have and shoot .222's, 223's and 22-250's (as I recall, it sounded reasonable at the time) I kinda compromised and shoot 52's and 53's.
In the FWIW dept. If you're just shooting Pdogs, plinking, or casual target shooting, buy the cheapest bulk bullets you can find. (no fmj's) You'll be shooting up a lot of them and the difference in accuracy between them and the high dollar ones is sometimes hard to measure.

Hello My mini 14 has a 1 to 10 twist , I tried a 60 grain vmax with 23 grains of h335 and it was all over the target at 100 yards so then i tried the 60grain vmax with 24.5 grains of h335 and it was alot better.
But its 1/2 a grain more than max .

By the way I let my buddy shoot some of the 60gr vmax with 23 gr of h335 in his AR 15 and it was great groups but it didnt work with im
