[QUOTE="Andy grubb, post: 1426099, member: 105429"] For me the two main reasons for a ladder test are 1: to find max load by looking for pressure signs. 2: to find best grouping by shooting 3-5 shot groups at a certain gr charge. It looks to me like you were shooting one round at each load so your target won't tell you anything at this point. Single round load is a great way to look for pressure sign and get velocities. And don't be surprised to say load 5 rounds at 45 gr and have your velocities differ by 10-15 fps between rounds. I normally start my ladder tests with 5 rounds per charge and go up in .5 gr increments to max. Shoot groups and find accuracy. Then you can tweak by .2 or .1 grs. If you find a load where you get good accuracy don't go crazy trying to tweak it. We all want to hit a dime at 1000 but less than 0.1 % of us ever will. [/QUOTE]
