Ladder Test for finding powder charge

Unless you're doing 10-round+ samples size at each charge, you're kidding yourself...

Yup. You dont really have enough data to have any statistics that you should have any confidence in.

The people who are talking about their ES/Std dev with 5 shots make me laugh .

You sure don’t need 10 rounds to find out what’s NOT good. JFC. Ladder test is to get a starting point without shooting a ton of ammo, right?

If you shoot a 2 shot “group” that sucks - why waste 8 more?

I don’t disagree. It’s just seems that seldom does a little tweak in charge weight take something from lousy to good repeatably unless it’s on the extremes of high or low pressure.

The follow up to this about how they’d do load dev is a good one. Not really what i do but close enough.

I don’t necessarily disagree. It’s just seems that seldom does a little tweak in charge weight take something from lousy to good repeatably unless it’s on the extremes of high or low pressure.

So what’s the best route? New bullet, powder, primer, etc. Fastest way to get to a good place to hone in, with fewest of amount of fired rounds? In the past, I’d pick a 3-4gr spread and load up a pile of 3-5 round groups to hone in, this way seems like I can get to a better place, quicker.

Like I said - my fist try at this and hope it’s useful for intended purpose. For me accuracy is more important than velocity.

Curious GH, what’s your accuracy goal? How many rounds do you shoot to establish your cone of fire and zero?

After today I bet you will have a better idea if it works for you than just advice from others. mtmuley

I’m pretty happy with a “true” 1” or less rifle at 100m. A couple 5 shot groups all inside that are good enough evidence for me with some proof at long range.
