Someone referenced a ladder test here recently and that inspired me to try one. Hadn't done one before. I was also trying out my chronograph that interfaced with my laptop to see how that worked. I loaded 10 rounds for my 6 Beggs LV gun. Use LT-32 powder and Berger column bullets. May 08, 2018 · You can test more than 10 rounds. To summarize, you’re basically shooting one powder charge per shot, logging your velocity and plotting on a graph. Chronograph: This method highly relies on an accurate, functioning chronograph, though I’ve been successful so far using my Caldwell 721122 Ballistic Precision Chronograph Premium Kit. “Well that looks interesting” I thought to myself. Then I got together with my friend Carl Skerlong to perform a 10-shot load development test for his Bergara chambered in 6.5 Creedmoor. Carl had loaded the rounds based on the instructions from the 6.5 Guys, and the results were very clear when visualized in Excel: (click/tap to enlarge) The best chronograph on the market is the CED Millennium 2 Chronograph. It is extremely accurate and stable, interfaces with RSI's Shooting lab software, and can be fitted with infra-red sensors which will "see" bullets under conditions (including total darkness) that would fail on other chronographs.

Chronographs Sort by Featured Best Selling Alphabetically, A-Z Alphabetically, Z-A Price, low to high Price, high to low Date, new to old Date, old to new Grid view List view The ladder is just one step in the process. This ladder target is by all means the ugliest I've ever shot due to the swirling winds and temp swing. If you read the detailed version of the ladder test theory, you'll understand that it is a very good test to utilize. There is much method to the madness. Sep 04, 2018 · Although there are many different techniques to design and test cartridges, the 10 Shot Ladder Load Development was developed to quickly find accuracy nodes through velocity testing. 10 cartridges are loaded to 10 different powder weights and shot over a chronograph to find each velocity. These weights will typically result in a line graph that ... Caldwell Ballistic Precision Chronograph. Illustration courtesy of Caldwell Shooting Supplies. After using a chronograph for a few years, I stumbled onto a "How to" video on the Internet. Specifically, "How to use a Chronograph." I have to admit I was a little bothered by what I was seeing. May 05, 2017 · In this episode, the 6.5 Guys meet with Scott Satterlee to discuss and demonstrate a technique he calls the "10 Round Load Development Ladder Test". This is a load development approach he has ... The best chronograph on the market is the CED Millennium 2 Chronograph. It is extremely accurate and stable, interfaces with RSI's Shooting lab software, and can be fitted with infra-red sensors which will "see" bullets under conditions (including total darkness) that would fail on other chronographs. This is a test done with the same number of shots as an Audette ladder, but done in an OCW format: View attachment 1150007 The pattern of barrel movement is obvious, and groups (single rounds in this case) can be easily compared side by side on 2 axes rather than just one. The best chronograph on the market is the CED Millennium 2 Chronograph. It is extremely accurate and stable, interfaces with RSI's Shooting lab software, and can be fitted with infra-red sensors which will "see" bullets under conditions (including total darkness) that would fail on other chronographs. Since each increment gets 3 rds, I also can spot potential accuracy nodes. The point that gives the best test group of 3 is then used for a second ladder with a .1 gr. variance. Most of the time that will indicate if it is actually a node. If the velocity is satisfactory at that point, my basic job is done. Content tagged with Ladder Test. November 1st, 2017 Long Range Load Development for F-Class. This article was written in 2014 for the Sierra Bullets Blog.It describes one method of load development that is commonly used. Aug 22, 2018 · First time trying the 10 round Ladder test with my wife's 6.5 Creedmoor. I could only get out to 230 yards where I shoot and this is what I came up with. i'm thinking I should load 5 rounds of 40.0 grains and another 5 rounds of 40.6 and find the better group. After I identified a promising range of powder weights using Audetter’s ladder test, my next step was to use Dan Newberry’s Optimal Charge Weight (OCW) Method to offset the “scatter node” drawback inherently present in the ladder test. To learn more about that, read this article comparing the OCW method with the ladder test. Well I should have used a shade. I went earlier this morning and there was no direct sun light on my chronograph and the the chrony read 169fps slower on the average when I was testing loads that came from the sweet spot in my ladder test. So, I took my 7mm08 and fired my hunting load across the chronograph and it read like it always has 2802fps. Another benefit of ladder test is it allows one to identify the upper pressure limits without necessity to break down the other four rounds once that point is reached w/conventional group shooting. Once all of the above have been determined, then comes the group shooting to fine tune the load. The ladder is just one step in the process. This ladder target is by all means the ugliest I've ever shot due to the swirling winds and temp swing. If you read the detailed version of the ladder test theory, you'll understand that it is a very good test to utilize. There is much method to the madness. Charge blade build iceborneWhen we made all the above corrections, our predicted velocities were within 5-10 fps of observed chronograph data. But your results may vary if you are using different primers or if your barrel has different friction characteristics. With any cartridge, you should always adjust for ambient temperatures and actual case volume. Sep 04, 2018 · Although there are many different techniques to design and test cartridges, the 10 Shot Ladder Load Development was developed to quickly find accuracy nodes through velocity testing. 10 cartridges are loaded to 10 different powder weights and shot over a chronograph to find each velocity. These weights will typically result in a line graph that ... The existence of the scatter node is the main reason the conventional ladder (Audette) test often fails to yield useful results--see OCW vs. Ladder on this site). The OCW load would then have the optimal amount of powder to push the bullet at just the right speed to be exiting the muzzle when this shock wave is at the other end (the chamber end ... The best chronograph on the market is the CED Millennium 2 Chronograph. It is extremely accurate and stable, interfaces with RSI's Shooting lab software, and can be fitted with infra-red sensors which will "see" bullets under conditions (including total darkness) that would fail on other chronographs. Reasonably speaking, any test using incremental changes in charge weight is a "ladder test", whether you're looking for accuracy or pressure & velocity. Which was the original usage of the coined term is probably material for a typical Campfire pissing contest, which I'm not interested in, because frankly, there are far more important things to be concerned with.

The Magnetospeed T1000 is a target-mounted hit indicator. Designed to “live” on the backside of a steel target, this rugged device uses proprietary light bending optics that bend light around the edge of a steel target towards the shooter. What the ladder test does at 600 yards that a chronograph will not do, is it takes into consideration the barrel vibrations with the bullet impact showing up on the target. I feel if you do the ladder test at the farthest distance that you will shoot it at like 600 yards, that the results will be valid.

I loaded 10 rounds for my 6 Beggs LV gun. Use LT-32 powder and Berger column bullets. The same can be said, a 500 yard target is all you need for a ladder test. I've done it, without using a chronograph for a single shot. I've had no clue of speeds, on several rifles, and I still found the node based on impacts. Found the velocity after the fact, working the DOPE backwards into a ballistic calculator. Jul 09, 2014 · Part IV: Performing The Ladder Test. The point of a ladder test is to fire a series of charges, each one hotter than the last. This gradual increase in the size of explosion contained in your weapon will naturally cause your bullets to rise or fall on paper due to a combination of speed and vibration of your barrel. Jun 10, 2015 · Phase 1 / Step 2: Load test rounds, 5 cartridges per charge weight (start at 15% below target accuracy load and work up in .3 grain increments to 10% over target accuracy load). Target accuracy loads can be obtained from a number of sources, the most reliable being the gunsmith who built the rifle. Phase 2: Fire and chronograph test rounds in 5 ... Not because it is unsafe, but because that charge area is going to look like a shotgun hit paper, when shooting a group. Because that area is not in an accuracy node. When you get three or four charges grouping, that's your node. Yes, they should have similar velocities, but an effective ladder test can be shot with no chronograph involved. 6.5 Creedmoor load development: Hornady 147 ELD with H4350 and H4831SC Hornady bullets are popular with the 6.5 Creedmoor crowd.

I was wondering if there is a standard or an average amount of rounds you fire through a chronograph, to determine the velocity with a specified load. For example do you shoot 3 rounds,5, or 10 rounds than get the average? I am trying to determine how many rounds of different loads I should reload to perform a ladder test. May 21, 2017 · 10 Round Load Development Ladder Test. Identifying a consistent and accurate load for your precision rifle while improving the overall efficiency of the load development process is a laudable goal. The 6.5 Guys met with Scott Satterlee to discuss and explore a technique he calls the “10 Round Load Development Ladder Test”. Feb 16, 2019 · When i do a ladder test, most of the time i don't have a target up. My Magnetospeed is placed in the same spot every time and I fire 3 rounds at a time, let barrel cool, do next 3 till I'm done. Close speeds i do a second and maybe a third test. If I use targets I set them at 100 yrds. Jan 03, 2017 · This is easily done with a “Ladder Test”. You may need to shoot several tests to find the load that suits you. Next, swap whatever available and appropriate primers you have through the above powder charge to establish a balanced ignition. Shoot this test in one trip to the range as you want everything to be as similar as possible. The existence of the scatter node is the main reason the conventional ladder (Audette) test often fails to yield useful results--see OCW vs. Ladder on this site).
