Found an awesome load development technique

[NinjaHunter]

Hey guys,

I've been tinkering with load development for 300 wsm once more, and while I was researching on load development methods. I found an awesome website regarding a load development method.

The load development technique is called Optimal Charge Weight Load development, or OCW. People in this forum probably heard of it, but I just wanted to share it.

Here is the website: http://www.ocwreloading.com/about.html

And attached is an excel table I made so it's just plug in the max powder charge, and reload.

Note: the attachment is an .ods file, so might have to convert to an excel format.

The OCW is a very good load development system. I've been using it for a number of years and it hasn't failed yet.
If you do decide to go with it, I would strongly suggest you send Dan the $45.00 consultation fee. An in-depth understanding of the procedure and target assessment usually follows a couple or three 'phone calls.

I've thought about the consultation, but decided to hold it off for now since I'm not very satisfied with my current rifle skills. I still need to practice my trigger squeeze and rifle handling via dry firing.

Once I'm satisfied with my rifle skills, then I'll go with the consultation.

There is nothing new or special with OCW. I recommend spending the $45.00 “consulting” fee on components and shoot a few more shots. In a nutshell, I would ... with a fixed seating depth and at a low end “safe” charge weight...charge cartridges in 0.3 gr increments (for cases typically using up to 35 grs of powder) and 0.5 gr increments for those above 35 gr. Shoot a series of 5 shot groups to the recommended maximum charge weight. Select the best group showing a minimum of vertical and recharge cases on either side with 0.2 or 0.3 grs ...shoot....select the best and start tinkering with seating depth.
My experience suggests there is no magic shortcut. Now, if anybody is exited enough to spend $45.00 on “consulting”, send cash to ....

My feelings as well. There are several ways to develop loads, but none are magic.

I agree 260. I find Dan Newberry a bit annoying in that he campaigns this load development method as if he actually developed it. This ladder test method has been around since before he was in diapers. I wouldn't send him a nickel for regurgitating something that's been around for at least 3/4's of a century and available from many sources.

I don't think Dan ever suggested he discovered the system but he has taken it up a couple of levels .. along with Chris Jones.
I have used Audette's Ladder, and still do, and found it far from perfect. I don't know how many times I've nailed a Ladder test at 100 yds and watched it fall apart at 200 and 300yds. Not so with OCW. I can't see what the issue is with some of you guys.

I don't disagree with what you are saying but I think we are looking a two different objectives .. one is a charge weight/seating depth that provides for best group and the other for an optimum overall charge weight /seating depth that will not necessarily provide the best group but does allow for more flexibility in charge weights. No magic, no shortcuts involved and it often results in the best of both worlds, especially in a hunting cartridge.

That difference is described quite well in the OCW overview.

As to the $45.00, I think the OCW method will save more than the cost of a pound of powder in the first couple of sessions ,particularly if you load for several cartridges... plus, it's an option .. not mandatory.

I do load development with the goal of achieving the best consistency (group sizes) at the distances I shoot. I can’t imagine my goal (or any other shooters goal) ever being second or third best, or in a particular range. IMO it is important to take the time to get it right and if that means more shooting ... there are other benefits as well.

Consultation fee? That is the funniest thing I’ve heard all year.

Check out Sam Millard from Panhandle Precision and his youtube videos, free no consultation fee.....and info as good as it gets

There is an old gunsmith on youtube I believe called The Old Gunsmith. He says he has built several custom rifles over the years. What he looks for is the lowest sd possible. Once he finds that he then plays a bit to fine tune. His premise is that low sd means consistency. To me the guy makes sense. I have not tried this or the ladder tests but I do find these ideas intriguing.

Would you please explain how he and you came to that conclusion?

for $20cdn I will say a prayer for your best group and point my crystals to your gps location ... 3 prayers for $45cdn

[Salavee]

The $45.00 fee is an option with OCW. Your's are a flat fee and the prayer may be waay too short to help me..

And if the crystals aren't working, I've got miracle spring water I can sell you to dip your bullets in

This may be just the cure for my ill directed projectiles! How much for said water
