your favorite/fastest way to find your sweet spot

[[email protected]]

Hello everyone,

I've always used a ladder test at 300 yards to try to find my sweet spot, do you guys have any better ideas? what about just shooting 5-3 shot groups with different powder charges near the velocities your looking for?

I always do a ladder test, pick the two spots I think grouped the best (which i could have been the reason why they grouped like that, so possibly never really finding the true node), than load five of those two groupings so I end up at around 20 bullets anyways, would i be better off just to shoot three shot groups maybe at 200 or stick to 300 yards?

Thanks!

I do the same ladder test 10-15 different charges then re ladder test the fastest nodes with 1/10th grain increments in those nodes but 2nd ladder test is at 400y,then group test the best 2-3 that node up. Takes more rounds but has worked well for me. I figure accuracy is no accident. worth the trouble imo

I'm stuck at 100yds mostly, so ladder tests are pretty much not happening for me.

I'll load up a box of 50 rounds, maybe with 3, or 4, charge weights, seat the bullets at known depth and go out and shoot. For .308, I'll probably make the spread .5gr and see what I see. The next box might be two weights 25/25.

It's part of the fun and it's practice.

A lot of members use Dan Newberry's OCW technique. I've used ladder and OCW techniques and prefer OCW.

For a new rifle I just take the max and starting charge from all the sources I can find and use the average as the start charge. Say I find three sources for my desired powder. I add the start charge and max then divide by 6 and that is my start with projectiles seated to max book coal. I add a tenth of a grain until I reach my desired velocity three rounds at a time. For the next range trip I tweak the seating depth and the charge a little more

OCW has worked very well for me. Be sure to follow Dan's instructions for reading your results.

I,m a OBT/OCW/quickload guy

pert much how i do it

Thou i do find max and work backwards, no point given up FPS for lack of effort
So the first thing i do regardless of how they shoot is load until primer wipe, i dont mean a lil smidge but a good print and stiff bolt lift. Back it it off .3 and that max for that rig/bullet/powder combo.
