Many thanks to Abinok and the others for turning me on to the ladder test. Had to develope a load for my 257 STW using Ramshot Magnum and 110gn Accubond. Ladder tested 20 rounds at 400yds. Sure enough, two distinct sweet spots at low (3300fps) and high (3500 fps). Chose the middle load of the higher sweet spot and sure enough, shot a 1/2 moa group at 100 yds (first four in .290")at 3490fps. Load developement in less than 40 rnds! /ubbthreads/images/graemlins/grin.gif Gotta love it, especially with a barrel burner like the 257 STW.
