Good morning to all..... I finally got to a point where I have aquired all equipt. and components to start reloading for my Rem. 700 .243 Win. I have 2 books with calculations and "recipes" for loading., Lyman and Loadbook USA. ) My first load components are: Winchester .243 casing, CCI lg. rifle primer, 36gr. of Varget,, I'm hoping for 3000fps.) and a Sierra 85gr HPBT. What looks funny is the O.A.L.. The book calls for 2.615. I took a casing and cut it length ways to just below the shoulder with a Dremel tool. This allowed a bullet to slide in and out of the casing with some drag and not with ease. I chambered the round in this casing, and found out where my "lands" contact was and measured. The measurement was 2.688 O.A.L. I seated for .003 off the lands at 2.685. It looks too long. Is this OK, am I seeing things or concerned over nothing ?? Lett'er rip and let the paper be the proof ??
