7 gr Unique and 9 gr 2400 for some slower loads in a bolt.
Runfivesrun method is quick and easy, just make sure the barrel is clean and the patch tight. Remington started off with 12" twists in it's M700s but for a few years used 9" twists but then went back to 12" twists. Best way to know is to measure as per runfiverun's instructions.

If you have a 1:9" then 69 gr SEI will get you to 5-600 yards. If you have a 1:12" you'll be stuck with 53 gr match bullet to get to 500 yard but past that you'll be running to slow and with that lite of bullet wind drift will be terrible. The New CFE powder gets real good velocities with both bullet weights. If your want to go past 600 yards you need atleast a 1:8" or better yet 1:7" so you can shoot 75 gr Amax or 77 gr VLDs! So it sounds like a rebarrel job for you!
My dad past away allmost 30 days ago and gave me the rem 223 and a rem 308. the 223 had been shot mabe 20 times and the 308 has never been shot.so if its got the wrong twist to go that far i will us the 308.I will check the twist like that here in a little bit.thanks for all the grate info so far
My condolances. You have good memories with those rifles of your dad..........

Very difficult to find fault with WW-748 in either 223 or 308 caliber. It has become my go-to fuel for the 223/5.56, and was when I loaded the 308.
I concur in the advice concerning the 69 grain Sierra Matchkings for longer-range work in 223. These shoot very well in all of my 223s, all 3 of which use 1-9" twists. The "down" side of the MKs is their cost, compared to the more common 55 grain weight-class for the .224" barrels. The 1-12" twist can run the cheaper 55 grain j-words quite well, and they are effective to at least 300 yards on rats. 90%+ of my varminting gets done inside that range spec. 1-12" twists might be a bit more lead-friendly than the 1-9" "default" setting and 1-7" to 1-8" "javelin-hurlers", too.
I had my 22-250 re-barrelled with 1-12" to exploit the lighter-bullet and cast boolit possibilities with (hopefully) more effectiveness. The OEM barrel was 1-14", and drove tacks with 60 Sierra HPs......so heavy-for-caliber to some degree is possible.

i have a rem 700 26" sps varmint profile .223 1-12 in a hogue stock, my son used when he was 15 and starting out in comps till he graduated to a 308. now my wife uses it.
use 55g or 60g vmax bullet, use the 55g to 300, 60g past 300.the 60g has 3 out of 3 cold bore shots on the last comps at 600 on a 9" plate. this is a target i shot during load workup. yes those are 1/4" blocks.even after 832 rounds thru it, it still shoots sub 1/2" groups regularly at 100 . this load is boring. it hits a 6" steel plate at 600 every time as long as your aiming it at the target
55 or 60g vmax
rem brass
cci primer
24.5g benchmark powder
2.29 oal, feeds everytime out of the factory magwell
55g runs 3100
60g runs 3075
eta: bullet speeds and oal

i have 2# of 785but not 748.I like the shots with the benchmark powder i will call the gun shop in the morning and see if thay have any of it left
is yours the 26" or the 20" "tactical"?. i cheated when i got that load, i shot hornadys and they shot real good, so i pulled one and compared the powder, benchmark is the closest and i adjusted the 24.2 from the factory to 24.5, and loaded it longer to get it closer to the rifling. the 24.5 in rem cases just clicked with my rifle, a 1/10 grain either way and the groups open up to a nickel size
no i dont think its a Tactical.i think its 23 1/4 thats to the beginning of the action.its not cheeting if it works good lol
oh , so its a sporter profile barrel not a varmint heavy barrel
Attachment 60554 The 223 is the one with the wood stock and the other is a 308 rem 700
My Remington 700 likes 25 grs. of H4895 behind Sierra 52 gr HPBT match boolits.
The boolit is the biggest contributing factor, then how concentic it is loaded in case and rifle, then powder. I have shot my best groups using Nosler 55 grain ballistic tips, 26 grains of 748, Rem 7 1/2 primers, Remington brass neck turned and zero case runout. Lots of powders will work behind a verygood boolit. Rifle is a factory Remington 700 BDL Varmit Synthetic 20" rem contour bull barrel:)
I have always used 26.5 grains of BL-C(2) with a small rifle primer under a 50 or 55 grain bullet seated to 2.260 inches.
