Re: Load Testing via the 'Ladder' method

when you fire the rifle the barrel resonates. it moves in a sort of figure of 8 shape at the muzzle. so the sweetest, sweet spot is in the middle where the line of the 8 cross. if you load your rounds faster or slower it changes where in the 8 the bullet leaves the muzzle.
When i am working up a load i start by doing the oal of the cartridge just a smidge off the rifling then i work up the powder by .5 grain increments. i go for the smallest group. then i try to stick with that load for as long as i possibly can. My shooting is really about hunting so i match my bullet to the game and situation i will be looking to kill it in. then look for a main stream non premium bullet theat meets all those parameters.
