[QUOTE="lynn, post: 85783, member: 1479"] Cowboy In working the ladder test i use the 1% rule on the powder increments.In your case i would use 0.4 grain increments instead of the 0.2 you used and this will keep your target from getting so cluttered up.It sounds like you had around a dozen shots in a cluster and at 0.2 grains that would be roughly 2.5 grains wide.That is about 0.5 grains more than my first guess would have been but it looks pretty good to me.If you had a working chronograph you could now go near the top end of your load and shoot 3-5 shot clusters while watching the extreme spreads.Lower is better in my opinion but if they start to drop then go back up again without ever getting low enough use te powder charge at te lowest point and try different primers.
