    I too, use the OCW process, but I use only one primer, and I verify at 300yds.

    Handguns....

    After all the paper research I load a box of 50 bracketed around what I crowd source as the likely load in .2 gr increments. 10 rounds each charge. 5 for accuracy and 5 to chrono all the while watching for danger signs. Just easier to do it that way with an old school chronograph rather than lining everything up. With the component shortage I might go to the trouble or buy radar.

    Rifles......(still learning)

    Ten round ladder looking for accuracy nodes. Takes forever but I do take the time to get rifle, chrono, and target all lined up for accurate data. My Rem 700 has .151 of jump so I am just loading to mag length. My next rifle I also plan to do the ten round seating depth ladder aka Eric Cortina.

    All that being said, I love the science so I am always tinkering and validating.

    Being still sort of new to rifle shooting and rifle reloading I have a long way to go, been shooting and loading pistols for a long time but that's a whole different animal so I do get a bit confused at times.

    I am doing this w/o any sort of chronograph so it's all shots on paper and looking for accuracy. I have described my methodology as this; work up initial loads in .3gr increments starting about .3gr above published start load. Load 12 ea and then shoot them in 3 shot groups each load at a separate target then repeat so that there are 6 shots on target and then repeat again on another fresh target. I can then superimpose them over each other to compare for 12 shots total.. This way I am not shooting just one 10-12 shot string at one target.

    My question to you all and myself is now that I am getting better at shooting and reloading I am having a hard time discerning which poor shots are operator error and not the gun or ammo.

    I am finding at times groups look great and where I want to be and then others that just fall apart. Then there are those that will string horizontally and then the next group with the same ammo string vertically. Though I am now getting to where I can tell that I pulled or dropped one.

    Unfortunately it takes most of us thousands of rounds to become consistent every shot. Check weld position of the rifle on both bag and rest grip, shoulder pressure and more. The trigger jerk needs way more refinement than the loads.

    I thought that was a fishin expression... Jerk at one end of the line waitin on a jerk from the other end.

    Still makes me wonder how much is the operator!
    My mentor just sent target pictures of his new 6mm bench gun.. Nine 1" targets, 3 shot groups. Two were one hole, four were two holes. Makes me sick!

    I may be guilty of having more than one time killer 20200803_192708.jpg

    Sounds like you are learning fast . As you gain confidence/skill in your reloading you will have that variable under control and soon be able to concentrate on shooting alone . Once you get to that level you will soon be able to detect human error , no matter how slight . I

    My best/quickest response from any rifle is always 1) powder charge then 2) seating depth on best powder charge - very seldom is that chronology not successful.

    It takes me about 100 rounds, sometimes way more, to settle on a handgun load.
    Took almost 500 rounds to work up a really accurate load for the 357 Henry.
