Anybody load the Rem 223 with Win 748 powder as an acquaintance I met at the range the other day reckons that 25.5 grains with a 52 or 53 grain bullet with this powder is the Bees knees for this calibre.
Bought a can to try and looking up the recommended loads in seven different reloading books I found at the lower end of the scale for a 52 grain bullet a load of 22.5 grains to start and a max of 26.5 grains and at the other end of the scale in another book to start at 27 grains and a max of 29 grains for a 52 grain bullet.
