once you've determined max, back it down & load in .3gr increments working backwards until you hit a decent accuracy node.
work around this area in .1gr increments until you hit that sweet spot.
By working backwards you achieve two things. You max out velocity and hit accuracy at the same time. Dig?
Load to max mag length and adjust charge weight to meet your goals. This way you accomplish all three things at the same time..
1. max velicity
2. achieve accuracy node
3. still able to load from mag
155 Amax will jump or jam... They have shot great for me either way.
When using a stock remmy rifle I've found that a 2.82 - 2.83 OAL to be just about where the max mag length is.
good luck! </div></div>
Wil, you kinda touched on this in the box the other night.
How do YOU know from the ladder (or a round robin OCW for that matter) that you are the max charge?
Your method skins multiple felines at once it sounds like, so I'd like to give it a go.
Thanks Brother!

Start with a clean barrel, load about 15 rounds in .2gr. increments (go about .4-.6 gr. above max published load and work your way backwards .2 gr at a time) and load 5 rounds of a safe load with the same powder (to foul the bore).
As your are doing your ladder test, start from the lowest powder charge and work your way up through your ladder checking for pressure sings, whenever you see pressure signs, that's you max load. Never go down below the minimum published load.
When you complete your ladder test, you will find that some consecutive powder charges are going to group, that's where your accuracy node is, you can use the load in the center of the group (if shot 4,5,6 group, use the load for shot 5). Try this load and see how it groups, if it shoots lights out, keep it, if not, you can fine tune from there.
