You need full length sizing in an auto if you are going to reuse the brass to any degree or use warm loads. You may get away with neck sizing in a 5.56 chamber, but a fail to feed will crush you in a match.

Semi-autos required full length resizing. Anything else and you will have feeding problems.
The head never gets resized. That's the end the primer goes into. Neck sizing is fine for a bolt action that you use same brass in exclusively.

Standard Lee dies. 50 gr Nosler BT, WW cases, Fed Match primers, 26.0 Varget. I was laying prone in 6" of wet snow in jeans, shooting off a bi-pod. Just loaded the mag, ran off 3, adjusted the scope and ran off more

AFhack, Congrats on the High Power.
For sizing, I'm afraid it's going to be full length. I use a match Hornaday bushing die with a Forster match seating die. Use plenty of case lube as well.
Be sure to uniform the primer pockets.
For 69 gr. SMK's I use 24.0 to 24.8 grs. of R-15 in a Lake City case with a Rem 7 1/2 primer to get things started. OAL is 2.25"
For across the course I use 77 and 80 Gr. SMK's I use 23.5 TO 24.4 grs. of R-15 in a Lake City case with a Rem 7 1/2 primer to get things started. The 77's are loaded mag length and the 80's are .015 off the lands.
These loads are safe in my rifle, 6 1/2 to 1 Nor Pac Wylde chamber barrel, and I have gotten at least 10 reloads out of brass using this data.
R-15 also burns clean if that means anything to you. Normally, I don't give a rip about how clean a powder is if it shoots well. It's sorta nice not to have to clean real hard for once.
