[QUOTE="Alan Griffith, post: 997221, member: 4686"] Mike, That was me who posted the ? over on Accurateshooter.com about testing for seating depth 1st before running the ladder. Tried it this morning. I had about 12 new Nosler 257 Rob +P cases that had slightly buggered necks right out of the box so I loaded them up with "starting" loads for a ladder. I shot 3-shot groups of .005", .045", .085" and .125" off the lands before starting the ladder. Good test. .005" was the worst (8") and it was a toss up between .045" (3.5") and .125" (3"). Glad I ran it. I ran the ladder with .045" off, had 10 nice shots @ 303 yds in zero wind and nodes at #'s 4/5 and 9/10 with .3 gr increments of IMR 4350 and 115 gr BT from a VERY custom 257 Roberts. This rifle i is known for being very finicky and I've now found another load for it that will be cheap to shoot (blemished Nosler's) and easy on the barrel and cases. Alan [/QUOTE]
