748 Hands down!
Know tons of people who swear by H 335..... but I've had a Ruger 77 223, blow twice, with a charge of 25 grains with a 55 grain SP Bullet... I don't trust it, period..
There are plenty of other options available.
On the other hand. If you ever shot a 223 with H 335, in it at night, in pitch black.... once you experience the fire ball it generates, you'll use any other powder but H 335.
you won't want to use it shooting prone on a field with very dried grass.... Can't think of any other powder that produces as large of a fireball once pulling the trigger..
