Hey guys, Ive got some thing WEIRD going on here. Im loading for a .270WSM, using once fired Federal brass from my rifle. My book (Hornady 7th edition) says case length max is 2.100. Out of 260 cases only 28 of them passed the go-no-go guage set to 2.100. after being thru my F/L sizing-de-capping die (Redding) The rest averaged 2.112-2.119, so I culled them untill I get a case trimmer. Next using 3 of my 28 good cases I partially set a Hornady SST, 150gr bullet and pushed it up to the lands/rotate and repete 3 times each with same bullets. My c.o.l. was 2.094-2.905!!! So I backed it off .015 and set my seating die to 2.890. all fit in the mag. But the book says 2.785 MAX. Well, I loaded 25 rounds(all of wich fit in the mag) but the bolt closed a bit too hard on about 10 of them, so naturally I backed them all off another .005 now all 25 are set to 2.885. Guess what, still TIGHT. I measured each and every one of them both times and Im not varying by more than .003 ttl. Is this a safety issue? Im heading out to test loads tomorrow so Ill post results and WATCH FOR PRESSURE SIGNS! But Im confused as to why only some are closing tight. Go easy on me, Im still relitavely new to handloading, but I want to know what Im doing wrong here.
