The 65 grain SGK is, IMHO, a great deer bullet in the .223. I load them in Remington cases, with a CCI 400 primer and 27 grains of Varget. This is a real case full of powder and sometimes requires shaking the case a little to settle it. It fills the case to just above the bottom of the neck. My LOA is .010 short of whatever the max is for my AR mags. It shoots well in my 7 and 8 twist AR's and my 9 twist Remington 700.
