Load Development Poll

[SSC]

Seeing how there is 2-3 main theories that are popular right now I thought it would be interesting to see what everyone does.

Apparently I need to clarify myself.

With a number of options out there on how to come up with the best load for any given rifle which is your preferred method at the following distances. Some say the OCW doesn't work farther out and some say the Ladder method doesn't work well up close.

For clarity's sake here are link to the different methods
OCW
Ladder

incremental step-ups: is simply starting at the book minimum (or where ever) and taking small step-ups in charge weight until you find the accuracy you are looking for.

Re: Load Development Poll

80 some odd views and only 17 votes??? I thought more would vote.

Whats OCW?

Here's the info for OCW or Optimal Charge Weight testing.

Re: Load Development Poll

How about another one: OBT.

Re: Load Development Poll

i like the obt but i dont think enough people have QL or some other way of developing data for an obt load.

Re: Load Development Poll

I went to the OCL site and there was a picture of an ice cream cone and some copy that read like a woman's magazine.

What is meant by "Audette Ladder" in this poll?
A Google search leads others asking the same question and sites with zillions of pop ups.

What is meant by "Incremental step ups"?
A Google search leads back to this poll.

Is this a snipe hunt?.. where the joke is on us?
Is this just a poorly defined task?

Creighton Audette was a gunmaker in Vermont back in the post WWII period.

Ladder Test Defined
What is a ladder test? A ladder test is, fundamentally, a method of testing a load combination using continuous increments while looking for a cluster of consecutive shots showing similar points of impact (POI). Usually the powder charge is adjusted incrementally while noting/tracking the point of impact variations in the vertical plane, and looking for plateaus on the target. The idea being that your best load will appear where several sequential, incremental charges impact in nearly the same place on the target. Basically you are trying to visualize a "sweet-spot" in the barrel harmonics by using the bullets impact on a target.

If someone posted a poll asking whether you enjoy differential equations, finite mathematics or finite element analysis more, the joke would be on he who was unfamiliar with those subjects.

Re: Load Development Poll

Here is an important scene from the Jacobs Ladder movie. Something like that helps me build up a load before I shoot it.

Re: Load Development Poll

I built a Jacob's ladder, with a model A Ford spark coil and an electric train transformer, when I was 10 years old. I can still smell the Ozone.

What make the arc move upwards is hot air.

Re: Load Development Poll


I think they are voting on which test they've heard of.

The query might be:

Of those of you who have used all three methods, which one worked better?

OCW is the "it", but its not for everyone. Get a load that shoots 1 MOA. Then, shoot 1 moa targets and have fun shooting rather than frustration trying to get a 1moa gun, a 1moa shooter, a 1moa bullet, a 1moa case, and 1moa loading techniques to shoot .2moa.

A sow's ear will never become a silk purse.

Re: Load Development Poll

I tried the OCW method for first time this morning on a rifle that I just put together, a Model 7 in 300 Blackout.... I'm happy with the results...next I'll try it with a heavy barreled 308.

Re: Load Development Poll

OWC is my choice. It's easy to interpret, fast and best of all it works.

Re: Load Development Poll

updated for clarification

Re: Load Development Poll

OWC all the way. Works very well and is easy to interpret.

Re: Load Development Poll

OBT is probably the best thing since sliced bread if you have QL. It has allowed QL to pay for itself a dozen times over.
